No official thread for this truck yet? Maybe this will become one. Anyway I invite everyone to ask questions, share their thoughts, experiences and observations on this great offering from Losi. I got an RTR as a birthday present a couple of weeks ago, that truggy is an absolute blast.

Cool, finally someone started a thread for this RTR.
I've got 5 tanks through mine and had a few questions for you. Since you just finished the break-in, how many tanks of fuel do you have through it, what temps are you running and what are you using to test the temps? What are your needle settings? What fuel are you using and what Glow Plug?
Thanks in advance? I'll let you know where I'm at after finishing my break-in today.

That's not the stock engine. I had a spare brand new GRP .21 silver head laying around, so I put it in off the get go. Didn't even start the stock engine. The GRP is nice, such a shame they don't make them anymore.

KHUDZIK,
I thought we all had GRP motors in our Losi Trucks. What does GRP stand for. Is it a manufacturer name or just a Losi name for the model of the motor?
khudzik
10-05-2009, 08:53 AM
GRP stands for Gandini Racing Production, based in Italy, Losi is partnered with them.

Thanks for the answer. So are they no longer producing motors as you mentioned earlier or are they just not producing the .21?
khudzik
10-05-2009, 11:42 AM
Their factory in Italy burned down to the ground a few months ago. I think they're back to making tires but they are done with engines, at least for the time being.

Ok got it. So is this .28 454 is a GRP motor?
khudzik
10-06-2009, 07:18 AM
No, it's not. From what I know the 454 is made by SH for Losi and is basically a Losi version of LRP .28 Spec3. Which in turn is an excellent engine. Either way you look at it the RTR is an unbelievable package for the money.

IMO the Losi motors are garbage. I dont care who makes them. There are three of us at local track that have them the 454s. Me being one of them. One runs good but was changed over to a turbo head the day it was bought. Me and the other guy that bought them have had nothing but problems. both were broken in correctly. Hes already blown one, losi replaced it. The new one he received after being broke in wont keep a tune for doo doo . Mine has had 2 and half gallons of gas ran through it. When it runs it runs great. Thats the problem, when it runs....... It wont keep a tune neither. 6 or seven guys that race all the time with plenty of experience with all motors have not been able to tune it neither. Runs good for a tank and then back to not running again. If your gonna buy a Losi dont buy an RTR. Do yourself a favor and buy the roller and put a good motor and electrics in it. Youll be very happy then...... Had to vent.......

10-12-2009, 05:00 AM
hdcruzer, I would have to agree with you. My 454 started life well and on or about 3 gallons of fuel later the engine just started giving me a headache. I took the engine apart because others was saying i had a airleak which i thought was true because of the issues i was seeing. When i took it apart i discovered that o-rings where being pinched and cracked, front bearing was trashed and i also noticed that the piston had a grove in it from one of the ports. To say the least the engine was trashed. top that off with the poo poo servos that came with the rtr this will be the last RTR i will buy from losi. However i will pick up a RR and not have a issue with that cause i will be able to pick my engine and the servos. After the dallors i spent on the rtr and replacement parts, i could have gotten a RR and started life alot easier with the parts that will last.
hdcruzer
10-12-2009, 06:04 PM
Yea Kicker, If I had it to do over again I would have bought a roller. The only thing that really makes the rtr a good deal is the receiver and control. Ive had servo problems also. Although beleive it or not Ive had real good luck with Jr 650. Still running it, and that was even running it a whole day with servo saver tightened all up. Got to admit though the truggy itself is indistructable..........

I just got into the sport and the local hobby shop was selling this RTR 2.0 T for 600. He said its been here so long he just wants it out the store so i grabbed it and i been thru 2 servos the clutch shoes flew off and the thing runs good if u dont try and punch it off the start. It just boggs down and kills. I hope that issue stops after about 20 more tanks i been thru 15 already. If anyone has a fix for the bogging down that would be nice..Anyway i love the RC action for being so new i guess.I had a Rustler before this one and that thing runs like a clock.. I guess i just got a lil dissappointed with these issues.

Well I have had my losi 8ight T 2.0 rtr for about 3 months now. I broke it in on 8 of stand and idle. It has a little less then 2 gallons on it. It was running good till tonite. I was running in a open parken lot with a budy doing some speed runs. Then it just sudenly stoped. When it happened I knew what had happen to it. I found this when I took the black plate off I found this. Broken conecting rod. Anyone else have this problem?

It was never ran had or lean. I broke it in then raced it a few weekend, because it was late in the season I didn't push it or run hard. Yea. Im gonna call losi tomorrow and see what they say. I have a feeling they will do nothing.

Worst thing you can do to a Truggy open parking lot, speed runs. There not geared for long runs at high speed...... But Losi has pretty good custumer service they might replace it for tou....

Got all the batterys charged and tried to run it. I cant seem to get the engine to run. it will run for 10-30 secs and then cut out. not quite sure what is going on, this was on the factory settings for the carb. tried leaning it out and it ran for 1 min then cut out, not sure what to do. All ready killed 2 batteries in the start box, recharging them and will try again.

Did you try to drain the unburnt fuel from the pipe? I would than pre heat the head with a heat gun or hair dryer if you don't have heat gun. If you are still breaking the motor in I would turn up the idle screw and as it breaks in turn the idle down. You will have to drain the pipe while it is breaking in. You will be suprised at how much fuel stays in the pipe while it is breaking in. Also you may have to check the glow plug.

picking up 2 fresh batterys to use in the starter box as the 2 ive been using seem to go dead way to soon and are getting really hot. ill try cranking up the idle, using a new plug and see if there is any fuel left in the pipe been trying to drain it.

The pre heat helps alot also. I have burnt up one starter box wheel because it it so hard to crank when it is cold. I have also puchased an ofna adapter so you can hook the starter box right up to a car jump starter and that has never let me down yet.

YA I hear ya I have five rustlers myself but it was time to move up. To be honest with you I use the adapter with the box. I purchased the jump starter from pep boys for $60.00 bucks and the adapter for $7.00 bucks about the same for two good stick batteries and could use to start anything car, boat, snow mobil anything. just an idea.

It took me awhile to just relax and figure it out. I used to get all pissed off but that doesn't help at all. And the forum is a great place to get tips and tricks. I also live in socal so I get to see alot of racing and that helps. So like I said just take your time and it will all benifit you in the end.

well after charging the new starter batteries and using a heater to warm the engine along with a new plug and tweeking the needles a bit i managed to get it to do its idle break in. ran 5 tanks of fuel threw it on idle then took it out and did some runs up and down the street to get some actual mileage on it. it runs fine for about 1/2 a tank then it starts getting hot quick. so i think a little tuning is needed i think the bottom end is fat and the top end is lean causing the overheating.

No, I just use one of them. I leave one battery hooked up and hook the adapter to other wire from the motor. I have a 12 volt battery pack/ jump starter I carry around in my truck. I hook it up and it works great for me. I've used it to start three trucks all day long with plenty of power.

The shock ends coming off is pretty common. I lost mine on the first jump I hit.
One of the tracks I spend most of my time at (Thunder Alley RC Raceway) Is very hard packed clay and the tires work great when it is wet but when it starts to dry out I loose a lot of traction.

Come to finde out while running the first tank of fuel at idel I heard a loud tinking that should not be. there were no bearings for the cluch and was missing a shoe. I am very disapointed in the lack of quality. I brought the car to the HS that I bought it from and they fixed it for me at no cost. It is a very good HS and that is why I go there, but why should they have to FIX a brand new truggy? Has any one else experance this?

My 8t 2.0 is only a few weeks old and works like a charm, had starting issues at first but these motors are known to be tight until broken in... other than that it's been great! As for the starter box, I find the one that comes with the rtr kit is sufficient enough to start it with two 7.2v batteries.

Have you tried the Hitec 7955 ? As far as the motor being tight I had to use a heat gun for the first two gallons to pre-heat the motor. Before I started using the heat gun I did burn up a starter box wheel.
Hope this will help.

These motors are tight on run-in. Heat 'em up a bit and if they get stuck, use a flat-tip driver in a cloth to tap the flywheel loose. It will happen a lot!

hey guys I am looking at gettting this truggy to get back into the rc world. I have been doing rc for 10 years now but mainly helis and a small hop with rc cars last year. Money is tight so I was looking at the 8t 2.0 to get back into racing at our local club. I have done alot of reading on the truggy so far and seem to read the same thing. Change servos right away, turbo head, change pipe etc. Is this deal worth the money for everything I need to change??? Will the truggy work the way it is ?? I am coool with changing stuff but seems if I change everything out right away I may be better off with a roller.
Is the motor good?
what would it take to make it a roller?
what is the pipe that comes with the kit?
will the servos last for a gallon or 2?
will the start box last better the the other losi boxes?
does the truggy work as good as a roller will or close to it?
also has anyonme tried the steel flywheel with this motor? I sued it on my 8ight buggy and it worked very well
Thanks for any help and info guys! I know you get asked the same thing over and over again hehehe!

Sorry, my fault! It does not! The stock servo horn adapter fits 23t output shafts and the Hitec accepts a 22t. Only way to make Hitec works is to use the servo horns that come with the servo. The HS-7954SH include a blue alumnium steering horn. Adapt hole sizes and you are good to go.

I also would like to know the exact (ml) capacity of the stock fuel tank with the insert and without.
150 with 155 without.

WHATS UP GUYS NEW TO THE FORUM. i HAVE HAD MY TRUGGY RTR FOR ABOUT THREE WEEKS RUNNING IT WHEN i CAN. I would like to know what the running temps should be after youtune the needles. I am runnin about 210 to 230 degrees F. It runs great but I feel it could have more power but I dont want to lean it out to much. It is still putting out alot of smoke and I have almost two gallons ran threw the engine right now. One other thing I noticed is when I turn it over with my finger when it get to TDC it kind of has two little tight spot like when the crank is turning over to start pulling the piston down. It is kinda hard to explain I was just wondering (if you understand what I am talking about) is this normal or should it be smooth when the crank makes the swing to pull the piston down. It still has pinch up top of the sleeve also. Thank you for your time and any info would be really helpful.

I picked up the truggy 2 weeks ago. I swapped the servos, turbo button, and RE11 in at the time of purchase. Idled 1 tank, putted around with 3 others and threw it on the track for the first qualifier. Leaned out a bit more on the second qual and then again for the main. Truck was slightly rich on top and bottom but made good power. Took the TQ and win (combined electric/nitro of all skill levels present).
Setup was 100% box stock (tires included). The truck is very capable.
I saw a lot of posts concerning the engine. I'm confident ALL of the issues were tuning related. If your engine has a bog, it is too rich because this engine has plenty of power. Temp wise, I've been anywhere from 230-275! The more tanks that go through it the cooler it runs. It has about a half gallon on it now and will get a full on race tune this weekend. I expect temps to be around 245.
The only issue I had was with a shock stand off. I pulled it out of the car and set it on the bench at the track and it broke. Not dropped, not hit, just set down and it broke. Must have been assembled way to tight. No big deal, replaced the part and raced the crap out of it.
The triple pictured isnt small, the 454 cleared it with ease (vehicles are about 12' off the ground at the z-pex).

Bought my RTR from RC Planet for 800 bucks with a few extras. At the time they where including a quart of 30% O'Donnell nitro, glow starter, charger comparable to a Prophet sport, and two 3300 batteries for the starter box. Not bad. I needed DSM anyway. When I recieved it one of the solder points on the starter motor had come undone. No biggie. Broke out the soldering gun and had it fixed in no time. When I finally got to break it in it was tight...real tight. So tight that I burned up my starter wheel pretty good and got stuck at top dead center. It was about 70F out and I did't warm it up with a heat gun first so thats kinda my fault. Was way too rich for my area so I had to lean it in alot. If I was a complete newbie that part might have made things a lil difficult. Then she fires up and I run a few tanks through it on the box(slightly rich). Then I throw it on the ground for a tank of gas of 1/2 throttle laps. Let it cool and go to start it and the flywheel is spinning freely. Went to G Force my LHS and grabbed a flywheel and collet since the old one got burned up. All I needed was the collet but ended up buying the flywheel too cuz Losi doesn't sell them seperately. Got back to the track fixed the collet. Broke it in. FINALLY I get to run the track with it. This is when I FELL IN LOVE!!! OMG this car basically drives itself. Handles turns like a dream. Always seems to keep you straight and "find" the line. Leaps huge doubles in a single bound. A VERY forgiving car. Fast too OMG is this thing quick. After weeks of running and tuning I ran it a lil hard and busted a shock standoff. When I went to make sure the other one was tight it just fell apart. So I picked some up. Fixed it and have been back out to enjoy it some more. The point is. These cars are certainly not "maintainance free" and working on them is a labor of love. You have to enjoy wrenching on them as much as driving them. or at least close to it;) I love this hobby and I certainly love the Losi 8ight T 2.0. Cheers!!!

Alright so I called Horizon Hobby in regards to my rims wearing as they rub the front suspension arms (trailing side) which they had not heard of this issue. So they gave me Losi's number direct, got an answering machine and left a message. My local hobby shop told me this is a known issue with this truggy and that there is a revised version of the rim, so I wa hoping Losi could do something for me. Either way, the truggy's been great and so has HH's support as I recently got a replacement belt for the bump box at no charge. Question is, has anyone else seen this problem with the rims? Here's a couple pictures of my truggy to show the problem. I had adjusted the throw and everything is good, but this rubbing only occurs on rough terrain where the wheels have play.

That's exactly it, the steering radius is severely reduced when you tone down the steering travel, so it's a losing battle. I'll pickup the wider wheel hexes tomorrow and post an update.

Alright, I played around with the radio and fine tuned the servo's travel... i've got it nearly perfect. Aside from the slight slop, the wheels work really well now. I did order the 2mm hexes to alleviate the situation though. I also confirmed at my local hobby shop that the AKA rims have no interference whatsoever; the Losi and Proline rims both had interference touching the arms with the inevitable wheel slop, so I know which set i'll be running this upcoming season. Just giving a heads up to anyone who's been following my situation or who has similar questions.

We love this thing, but is it safe to start leaning it out for speed after about 1Kcc of nitrotane 20% sport?

It's not ready until most of the pinch is gone, otherwise your can snap the conrod very easily.
Best way to check is to take the glow plug out and turn the engine over with your hand, if it sticks very hard at TDC it needs more time to break in. If it stick just a little it will be fine to start leaning out.

that sounds like just the pro-tip I was looking for. :)
I can get it to turn over by using an additional finger on the top of the flywheel, but i would think it is still considered too pinchy for good speed. I'll run a few more tanks through & check again

04-01-2010, 10:27 PM
You don't need to buy a failsafe because it's already built into the 2.4 Spektrum reciever. After turning on your controller turn your truck on (motor off). Then turn the controller off and see which way the throttle servo goes. Whether it applies the brakes or gives it throttle. If it opens the throttle follow the instructions in the manual to rebind with the correct settings. This feature will kick in if the voltage drops too low or if the reciever loses signal from the controller. As far as 12v in the starter box I'm not sure and don't want to give you bad info. But curious myself...lol. Hope it helps.:D

ya normally you only want to charge a pack at 1c meaning 1000mah would be 1 amp and so on. Sub C can handle alot more but as you said it will shorten there life span. These small cells in the hump packs can handle more but there is no need to stress them so I only use 1amp and keep a few extra packs on hand.

I charge nihm rx packs at no more than 800mA often as low as 600mA. No need to stress the cells for peak voltage what you want is capacity, and you get that with a lower setting. And longer life from the pack as well.

Well the breakin is pretty much done now. I burned almost half a gallon now doing the heat cycle method. The truggy never missed a beat and the start box worked perfect even with 2 old 7.4 volt 1500mah packs. Going to switch it over to a gel cell 12volt though later this week. I did preheat the motor to atleast 190f everytime and will keep doing so for the life of the motor.
The 454 has a ton of punch even when it is still really rich and still tight, hoping it will drop its nuts buy the end of this gallon then we will see how it really does out on the track. Also hope my pipe and turbo head is here this week. Even running as good as it did it never got over 230f on a temp gun. Oh ya anyone having trouble getting a good reading out of there installed temp sensor I found if you spin it so the small sensor is to the back of the head it will give a more accurate reading. Mine was never off more then 10deg this way. Never perfect but gives you a good idea on where your temps are.

Losi/Joey

Losi/Joey
04-04-2010, 07:27 PM
well heres the thing. As for factory settings are good to start with sometimes you have to do a little tweeking to get it right. Not every engine is exactly the same so sometimes you have to mess with the needles slightly. Im not saying to start going at it like a mad man, just maybe an hour counter clockwise on the low end. you should be getting fuel to come out but not a puddle after a short idle.
seattlelife22
04-04-2010, 07:37 PM
Do you mean clock wise on the high speed needle. counter richens it. i could be wrong.
Losi/Joey
04-04-2010, 07:48 PM
Im sorry, yes clockwise, not counter. wasnt thinking straight. you can do it on either the high side or low side but if you do it on the high side it also leans out the low side simutaniously. start with the high side and see what temps you get. usually an hour on the clock raises temps about 10 to 20 degrees.

you can install it before after, it will not effect the breakin and you will not have to break it in again after installing it. If you got one go ahaead and drop it in with the shims that it comes with and go tune for the turbo head. Make sure get the old shims out before installing the new ones.
seattlelife22 160 is way to low, with the temps that low all you are doing is slamming the piston into the tapper iin the sleave. You need to get the motor to at least 200 to 230f. If you havve to lean the low alittle to get it done then lean it out some amounts at a time. Also make sure you are warming the motor before you even put it on the start box. I use a heat gun to get the motor up to 190 to 200 before I even try and start the motor. You motor will love you for it and it will make life alot easier on you as well.

It will give you more power, more rpm, lower temps and improved fuel consuption. It is well worth the $20.00. Also upgrade the pipe, the stocker is not very good. I just got the re11 but havee been hearing good and bad about the pipe so I am also going to try a jp3 which seeems to work good on alot of motors.

Just that it robs the motor of top end speed, I have only read that and do not know for sure tell I try it my self. The jp3 works good with any motor but is a fuel hog and with thhe 454 already being a fuel hog it may be thhe wrong choice as well. I just it all depends on what you are looking for.

Well I burned a few tanks on the 454 today with the turbo head and re11. Had to retune huge but after getting the motor tuned but still a little fat the motor was rocking. It had a ton of power and never went above 209f. It was cold out today so I am sure that had alot to do with the low temps but it was pulling huge. So far I am really liking this combo but will have to see how it does at the track next week.

I'm still undecided between the re10 or re11, I want more bottom end grunt... top end doesn't matter to me really. And if the turbo head really makes that much of a difference in temp and runtime i'll throw one on as well.

04-11-2010, 08:37 AM
ya if you are looking for stump pulling low end I would go with the re10. The re11 still has good low end with the 454 but I did notice I lost a little low end even though it is still rich.

Well my RTR's 454 will not tune... i'm hitting 300 degrees F, I have changed the plug, had the lhs tune it, two guys at the track tune it, and no matter what it's still hitting 300F! I'm calling Horizon Hobby this week to ask what can be done, it's only used under two gallons and I have yet to get a smooth run from it. I am planning on running the re-11 or re-10 pipe, and have considered the turbo head, but this is ridiculous. If I do have an air leak, will Horizon Hobby warranty the motor perhaps?
sluggo
04-11-2010, 06:19 PM
is the motor hitting 300 on a temp gun or your radio? Sounds like to me you have a air leak. It is simple to seal the motor up (I did mine before I even put fuel in it) Get some high temp silcone. Put a small bead around the backplate, carb neck, and needle stem. There is a vid on youtube that shows you how.
Also to hit 300 you would have to be lean on your needles, mine is running no more then 225 today but still alittle rich. Both my needles are just under flush but not sure on how many turns out that is. I have read many times that changing to the turbo head and pipe that will also bring the temps down.
What fuel are you using and how much nitro does it have??

I am going to say this. this weekend was the first time i have had fun and laughed at the track in long time. i had a revo and everytime i went out there i broke something. it was such a good time. temps were awesome. i was running alittle rich but who cares when it still had power like it was no ones business. airleaks are a breeze to seal. imo. thanks for everything.

I was running rich, lol. And i'm running Sidewinder 20% (20/12) The temps i'm giving are from the telemetry on the radio... I have yet to pick up a temp gun to get a more accurate reading.

yeah dont go by what the temp says on the controller, because its far from being correct. Invest in a good temp gun and use that to verify your temps. your most likely below 300 degrees its just mis reading like they all do.

Exactly what i'm hoping... I guess i'll have to get a temp gun on my list on things to get before taking it into the racing season. Anyone know a good writeup/pictorial for rebuilding diffs and overall maintenance on the 8t? Someone posted a decent writeup on these forums for the diff rebuild but had a reply saying it was incomplete and missing steps... i'd like a sure footed guide to maintaining my truck before really driving it into the ground.

Alright so I called Horizon Hobby in regards to my rims wearing as they rub the front suspension arms (trailing side) which they had not heard of this issue. So they gave me Losi's number direct, got an answering machine and left a message. My local hobby shop told me this is a known issue with this truggy and that there is a revised version of the rim, so I wa hoping Losi could do something for me. Either way, the truggy's been great and so has HH's support as I recently got a replacement belt for the bump box at no charge. Question is, has anyone else seen this problem with the rims? Here's a couple pictures of my truggy to show the problem. I had adjusted the throw and everything is good, but this rubbing only occurs on rough terrain where the wheels have play.

And an update regarding the stock rims rubbing... well I installed the 2mm wider hexes (LOSA3532) and problem gone. :)
As for my 454 overheating, picked up a temp gun and discovered the onboard temp sensor appears to be giving inaccurate readings... so a replacement sensor is on the way.

Anyone having problems with there shocks leaking?? I have 2 that are so far, I can't see the seals needing to be replaced already. The motor is running awesome with the turbo head and re11 pipe. I have a gallon on it already and it is really starting to scream. It still has a ton of pinch so it can only get better with the next gallon. Nevver temps over 230 to 240 even with thhe tight pinch, so I am hoping with the next gallon the tempps will come down even more and I can lean it out some more.
I mmust say this is a very very tuff truggy, My rx battery came unpluged well full throttle and I had a ver bad run away. After hitting 1 tree 2 houses and 2 fences before I cought it. Not 1 bent or broken part :)
I picked up the truggy 2 weeks ago. I swapped the servos, turbo button, and RE11 in at the time of purchase. Idled 1 tank, putted around with 3 others and threw it on the track for the first qualifier. Leaned out a bit more on the second qual and then again for the main. Truck was slightly rich on top and bottom but made good power. Took the TQ and win (combined electric/nitro of all skill levels present).
Setup was 100% box stock (tires included). The truck is very capable.
I saw a lot of posts concerning the engine. I'm confident ALL of the issues were tuning related. If your engine has a bog, it is too rich because this engine has plenty of power. Temp wise, I've been anywhere from 230-275! The more tanks that go through it the cooler it runs. It has about a half gallon on it now and will get a full on race tune this weekend. I expect temps to be around 245.
The only issue I had was with a shock stand off. I pulled it out of the car and set it on the bench at the track and it broke. Not dropped, not hit, just set down and it broke. Must have been assembled way to tight. No big deal, replaced the part and raced the crap out of it.
The triple pictured isnt small, the 454 cleared it with ease (vehicles are about 12' off the ground at the z-pex).

I thought I had mine almost broken in, but yesterday after running for about 10 minutes, the car just stopped. I brought it back to the starter box which took me about a minute since I was about 100 yards away to find the flywheel locked as if the engine was brand new. Tried to push it back with a screwdriver and it wouldn't budge. I brought it back to the house to use a heat gun and finally got it moving again and able to start. What could have caused this and is this normal for a newer engine? (I've only run about 12-15 tanks so far).
Also, I noticed yesterday at full throttle the car seems to accelerate but then dies after a second or so. Could this be a throttle servo adjustment? Maybe it's pulling too much?

Check out the "Nitro Off-Road" thread on rctech.net
It has a very informative section called the "Break in Bible".
It's very helpful and will help you understand fuel mixture/settings more than anyone can explain it.
To help answer your question though......I will always idle a tank or two through a motor and then you need to start driving it.
Very slow circles or passes and trying to keep the motor around the 200F mark.

I was doing a quick run today and the steering servo went out in a big way. The truck started to become a little twitchy and didn't make turns well. I brought it in and changed the hump pack since the voltage dropped to around 5v (didn't think it was a big deal) and then restarted it and went out again. Luckily I went to the fenced area of my yard. The truck spontaneously went full throttle and into my patio set.
When the steering servo is plugged in the throttle goes wide open and the steering twitches. This is with two different receivers.
I am debating on getting a hv hitec for it but would likely not run it with a lipo right away and use a hump pack for a little while.

I believe i've come to the conclusion the cause to this is low voltage. It happened to me twice, with the stock servos and once after I swapped out the stockers for hitec servos. Both times it happened when I ignored the low battery warning on the radio. Lipo will greatly improve runtime, so will a higher mah nimh battery. I've also read that the spektrum rx's are known for malfunctioning on very low voltage. Other than this quirk, the radio system (tx and rx) works great.

05-30-2010, 09:56 PM
I figured it out. The receivers were transferred from another truck and I reversed the throttle direction and the failsafe position was for the other trucks setup. It 'fixed' itself when I rebinded the receiver during the checkover with losi support. A dumb mistake on my part.
Low voltage happened, though, I ran the truck too long without charging it because I am just doing the break in and have been driving it easy and for a tank at a time.
I love this truck, though. My goodies should come for it this week.

ya that sounds lean, bring the hsn back to flush with the brass and tune from there. That should bring you close to where you need to be. Also on the lsn you should be just a little in from flush. Every motor will tune different but that should get you close enough that you can tune a hour here and there.

I am brand new to the forum (and RC cars for that matter) and am asking u experts for some help. I recently had a problem with my 2.0T where the flywheel stopped communicating with the piston. I took off the engine and found that the flywheel dug into the collett. I ordered a new flywheel which comes with the collett and replaced the collett and it works great now. The problem is, when the engine is off and i'm rolling the car the piston moves up and down. When the engine is on and I stop the car the engine dies. It was tuned perfectly before I took off the engine. It's almost as if without gear movement the piston won't move. Any thoughts? I'm wondering if I screwed on something too tightly where the flywheel mechanism is fixed to the gears. Any help would be appreciated. Thanks a million!

Hey guys just a note if you are looking for a good pipe for the 454 I tried the orion 2013 today. After getting the motor tuned the thing was pulling like mad! It also had great topend with a little over rev. The real nice thing about this pipe is the sound. So if you are looking for a great pipe give it a try. I am hoping to also get a 2057 which will rob a little low end but will increase run time and topend.
I never use a temp guage. The DX3S system temp is not accurate at all. I use water to tune my engines to temp. It is reliable and easy.
How do I do this ?? leaned mine out a little but still need to tune it
I have put a gollon of fuel through it so far.
7 tanks to start with, then slight adjustment on the mixtures and anther 7 tanks before first race.
Second round (1st race neet) I managed to bend a shock arm.
I was able to bend it straight again. In the third race the brake/accelerator servo went and that was me for the day.
I have now ordered titanium shock arms and will replace all of them. Also heard the plastic tops on the shocks break so replacing them with aluminum ones.
I have moved the steering servo to the brake/accelerator position and got a bigger steering servo. Also replaced the steering horn for a aluminum one
For the starter box I have installed a 12v 7Ah battery, been told it should last all day for a race meet without being charged ;)
I have ordered some new rims and grass tires ready for next race, cant wait.
Hope nothing breaks next race hehe.

After getting the motor warmed up put a couple drops of water on the cooling head and if it takes more than 6 seconds to evaporate the motor is running too cool (too rich) and if it takes less than a couple seconds it's running too hot (too lean), the ideal evaporation time is 5 seconds. this is all based on the boiling point of water. Some people use their saliva in a pinch to get an idea if they're running too lean at the track if their temp guns aren't handy.
cool thans for that ill give it a try :D

WOW.... Do I need to say more?
Me and my brother got us each a 8IGHT-T 2.0 RTR and this is some serious machines.
That 454 is a monster! I only have a Traxxas Revo with a Picco .26 to compare it to but listen to this.
We have built a home made track (http://www.youtube.com/user/Klimpen717#p/u/3/DW-TO7-So0o) and spent hours and hours on there with the Revos.
After TWO laps with the 8IGHT I ran faster lap times then I ever did with the Revo.
The 8IGHT is still only at 60% performance and running VERY rich due to break in.
The track became way to small over night, I can tell you that! We need to expand!

Now when we are talking engines here. Can you suggest a engine for the 8IGHT-T that cost LESS then $200. I'd rather go for mileage and easy tuning. I only race on a homemade track and it's NARROW.
So a .21 would be right huh?

Should've got the M3. I'm not sure if I was thinking out loud with that post or just lookin for a reason to get a new pipe. Although the RE11 might pay off. The track I run on mostly is a large fast track. And on another note I switched over to 25% for a smoother idle and a better running motor overall.

Yea, that was pretty funny, but no I did not lead the whole race. I was too nervous. I was a little relieved after I crashed and some cars passed me. After a while, I started to relax and get into a groove. Ended up finishing 2nd but I know I will do better next time.
Our track is very tight, and that is why most people run the .21 on it. I really like the torque of the .28 though. It suites my driving style well.

And what do you mean by that? Posting a quote that Losi use in their advertisement???

I ordered the turbo kit. Has anyone done a direct comparison before and after adding the head? How noticeable is it?
I have not but from all the research I did it seems like a good investment. I am going to order mine soon, I want to get the re11 pipe also.

You have to take a screw driver and turn the motor over till it loosens up. The little sprocket is called a flywheel, on the bottom side of your chassis stick the screwdriver in and slowly pry the flywheel. Once you turn it far enough it will loosen. Then you can put it back on the starter box and try to start it again. I recommend you heat the motor up with a hair drier or heat gun and that will help loosen the pinch on the top so it turns over easier. Also, loosen your glow plug 3/4 turn and once it starts tighten it back down.

i have also ordered mine, let you know what i think once its installed.
Can ppl give me more info on the main differences between the re11 and re10 pipe
Also which they prefer, i race on the grass :D

RE11 is a bottom, to mid-range pipe, RE10 is a mid to top-end pipe. Also the RE11 is a carbon copy of a O.S. 2050 pipe.

You got them mix up bro.
It is exactly the opposite.
Neobart
08-04-2010, 05:56 AM
Nope I don't. The re11 is longer and a little slimmer than the re10, long pipe=more bottom end, shorter pipe=more top.

Sein is right, I assure you. I got a noticable difference in the low end with the RE10. With the turbo head it runs cooler but now I'm getting some wheelspin. Our track is a real fast/large one so for me I think the turbo head and RE11 might be better for me. Now I'm curious about that RE11 being similar to the OS 2060. Hmmmm As for those pipes... the 2050 is the low/mid pipe and the 2060 is the top end pipe.
Neobart
08-04-2010, 10:41 AM
Well there you just contradicted yourself, the RE11 is a carbon copy of the 2050 pipe. The 2060 and re10 are supposed to be similar, but not identical.
Straight from Losi's product page:

Well how about that...:rolleyes:
Lapper
08-04-2010, 06:39 PM
In my line of thought, a longer pipe would have more internal volume and thus take more time to fill with pressure making it more of a top end pipe. A shorter pipe in turn pressurizes much faster making it a better low end pipe. Just my way of thinking. Not based on any facts just my assumption. But as far as the RE series pipes, I knew that one, not only from Losi's site but the forums also.

Think of the tuned pipe like the pipe on an organ, the longer it is the lower a frequency it resonates at.

cool thanks for that info.
And thanxs also to sein, thats the same info i found today on amains site.
I think ill orer the RE11.
Any guys played with their steering Servo Saver??
I complained to some of the guys at the races on sunday, how even with a better steering server it seemed like i was taking corners alot wider than others.
THen friend showed me the steering Servo Saver and we screwed it almost all the way in.
Next race my steering was way to sensitive. SO ill have to take it apart again and back it off a little before the next race.
How much thread from the bottom are other guys running :confused:

turn it all the way in then back it off 2 1/2 turrns. Also locktite it there or it will back off again.

thanxs bro,that should keep it where ya need it :D
To get better turn in I dremeled my hubs. It works great. My servo saver is still real loose.
If you are on a tight track try adjusting your rear hubs. You can move both spacers to the rear and it will push your hubs forward making the wheelbase shorter and give it better handling for tighter tracks. You can also use the short ackerman plate and it will also help with your turn in.
Remember, whatever you decide to do, only make one change at a time. So that way you know how it effected the vehicle.
Done a few upgrade on my losi
New braces front and rear, did the diff oils while it was apart, 7k, 7k,5k rear
also put new pipe in RE10, man it has made a massive difference, ripes the grass up when it takes off. WIll install the turbo plug next to see the difference again, caint wait.

What is the stock glow plug that came with the Losi 454 engine?
I had the stock one during break in and then another gallon or two.
Finally it gave up and I put in a O'Donnell Purple plug but I'm not sure that is a good one.
I use those in my Picco .26 (Revo) and there they are bullet proof. Not so much in the Losi 454.
So I would like to try the stock glow plug again but don't know what it is!
Perhaps another suggestion about plug for that engine?
It's the DYN2495:

Thanks mate!
I see that those are not that easy to get a hold of.
I was out on the track today and used the O'Donnell Blue glow plug and it works OK so I'll stick to it for a while.
I got another problem with the car. All of a sudden the rear diff "jumped gear" or what to call it??!
I could apply full brake with the car in the air (my bother holding it) and then I could turn both rear wheels at the same time (same direction) and I could hear the diff making a strange noise and skip over to the next teeth inside....
What to do?
No problem. With the rear diff, I don't know. A few people with 8t 2.0 have had problems with that diff.
I haven't took mine apart yet because I think I will have problems too, lol. It has been running great and I have just about two gallon on it. It is over due for a fluid change though.

Less area (volume) would mean less compression too I think!

No, the same sized piston trying to compress less volume would equal more compression

Ahh, do you all mean less volume in the COMBUSTION CHAMBER???
I thought you meant the button head had less volume (giving more volume to the combustion chamber).

I finally got my re11 pipe and the turbo head on my truggy. I have a race this Sunday so we will see how she performs. I will also get some video footage.
I'm real excited, just went through the whole truck last night. Took everything apart cleaned it and tightened it back up. I replaced things that needed to be replaced, put fresh shock oil in, and now she is just sitting looking pretty :D
I even took the engine apart and cleaned it. That 454 motor is almost on it's third gallon and it will still push the sleeve out of the case when I turn it over. This engine is a beast. I can consistently get over 8mins of run time on a tank and if I am not pushing it I can get 9mins:eek: I know some will say bs but I will record video so you can see for yourself. The way this engine runs I would never buy another motor. I saw one sell on ebay for $75 brand new!!!
Anyway, I just looking forward to the weekend of racing and I will update everyone on how it went. Wish me luck :)
It was a beautiful day this Sunday, but I had a bad race weekend. I have been using these cheap servos, and they gave me problems this weekend. So, I am getting the famous 7955 or the 7950.
BUT the motor was monstrous!!!! I could not believe the difference in performance. The track I run on is not very big most racers run 12 or 13 toothCB and 50 spur. Because I like the .28 I run a 15:50. With the stock pipe and standard button head it pulled it well but nothing like the re11 and turbo head does. As soon as you fire the engine up you can immediately tell a difference. The tune I had on the stock pipe and standard head was rich for the re11 and turbo head. After I finish adjusting the tune It was crazy how hard it pulled. I thought by running the re11 I was going to lose a little bottom but I gained a lot! It was great to say the least.
My wife was not able to get any video of me because she was wearing slippers and could not come by the track :mad: Next time for sure! I will probably make a vid of it just running around so others can see and hear it.
All in all, the motor is sick, and I will be getting another after this one dies.

For $270 You can pick up a TQ .21 which is a carbon copy of the GRP tuned .21. Just recently broke this motor in and OMG. The 454 was nice but seemed like too much for me. The GRP gives me usable power that never tachs out. VERY happy with this motor. Used to be what the Losi Team Drivers ran before the factory burned down and they made the switch to Novarossi. Just thought I would share. :D

I have noticed some slop at the rear inner hinge pin brace and the rear hinge pin. Is that normal or my bad landings? Pins look good not bent. Next my rear outer bearing keeps blowing up, my fault? Would the upgrade rear hubs help?
Lapper
10-19-2010, 11:00 AM
Yes, no, and yes. lol. The plastic bearing inserts do wear with time. The alumininum one will last. Even if your hinge pins are straight the holes in the braces oval out easily. Instead do yourself a favor and get the adjustable hinge pin braces. Not only are they adjustable but the inserts are replaceable and cheaper than buying multiple sets of braces.

Best advice I've heard in a while. The first thing I did was get the adjustable hinge pin brackets. Not only is it easy to replace the inserts so that you never have any slop, they come with tons of inserts of varying degrees. They also look very cool.

Two questions:
Anyone know where I can buy a replacement grommet that connects the pipe to the engine? Mine is all worn down and now smoke is coming out of that area when I try to start, which I think is the reason it won't start. I've looked all over but I can't find anything. Maybe I'm using the wrong search keywords.
Also, has anyone had a problem with the DX3S radio not turning off? Mine won't turn off and nothing bad happened to the radio. Just went to turn it off and it wouldn't. The button seems fine. I had to take the batteries out, but once I put them back in it turns on.
Any help is appreciated, thanks.

If your talking about the rubber exhaust gasket, any one made for .21 to .28 engines will work. The HPI ones are a lil thick though. I've been using THS and Sweep Racing gaskets.

150 dollar range, you ought to get your self a hitec high voltage man. much better. i like to use fast ones for throttle and stronger ones for steering.

Hi there I use the hitec 7995TG for my steering and cheap savox for the t/b most of the guy's at the track use the Hitec for the steering
heres the spec for the Hitec
Motor Type: Coreless
Bearing Type: Dual Ball Bearing
Speed: 0.19 / 0.15 sec @ 60 deg.
Torque: (4.8v/6v) 18 / 24 kg.cm
Size: 40.00 x 20.00 x 37.00mm
Weight: 65.00g.
when i put this in my Truggy I tightened up the servo save nut which give me better steering.
hope this helps
cheers Jazztaz
