HI Guys, I have a rtr 2.0 Truggy. 3 weeks old. I cant win get one thing fixed and another thing goes. My throttle servo took a dump today. Ive only ran about a gallon of gas through it. Finally I can start having some fun and then this happens. Im hoping Losi will replace it. I have e-mailed customer service just waiting to here from them. If losi will not do anything which Im sure they will, Ive heard there customer service is great. What do you guys reccomend as a good replacement that wont cost me an arm and a leg. Mine does have the better JR Racing Z650 M for steering but it had the cheap Z270 for the throttle. Ive had no problems with steering servo,but want to know if they are prone to failing also. Thanks Rick

get use to the servo thing as they havn't fix that problem i my mind. i have blown 4 of them so far this year..yes yes i did the epa correct and thought that the servo might be to close to the chassis so i added a 1/8 spacer under the throttle servo to help out.. well it did but after 4 weeks guess what happend tonight..yep blown another servo. and because of this ,cost me 1 place in the sesson point.. thanks losi for making find product..??

Same here. Fried the original, Fried a hitec hs-645mg then a spare traxxas servo 2075. Endpoints all set. Bought the truggy in july. :/ I know the original and the traxxas should be scoffed at but the hs-645mg is a workhorse.
What is the EPA correct? Thanks Rick
EPA end point adjustment. It makes sure your servo is not over extending itself and is a setting on your radio.

epa is your end point on your servo so it does not bind or make the motor over work. i have spent good money on servos for this. ko pro po. futaba, and airitronics. wont use cheap stuff in my truggies but i desided to just go brushless next year and do away with the throttle servo issue

The Servo in there right now is a JR Z270. I really dont have a lot of money to spend at this time. Im not into racing yet still learnig. But will be trying in the next couple of months. If losi wont do anything, would the JR 590m be an exceptable upgrade for now? Im using the Z650M for steering right now and it is working great with no problems yet. Thanks Rick

i have been running an ACE DS 1015 for 2 years on both my losi 8ight buggys 1 year in the 8ight and now in the 8ight 2.0 i have never had a problem, i suggest u buy decent servos like ACE DS 1015 i fried everything i put in there up until i put an ACE in

Someone at my local track suggested the aluminum rear chassis brace to keep down the flex in that area. Not sure though.
As far as cheap servos go I have 10 nitros and never put a throttle servo in over 40 bucks and never had issues till now. Just saying.

Neither the 270 or the 650 will withstand the abuses of 1/8th scale racing. Invest in good servo's and avoid frustrating yourself.

I don't know why I have seen people post that both of these servo's have held up for them!! I understand driving on the street in striaght lines, but for any off-road racing, or even bashing these servo's are really just junk, and could not see anyone completing a minimum 2 10min quals and a 20+ min Main on a off road track.
For example I had a 270 in a RTR (non Losi) that I bought as my first Nitro. Failsafe kicked in one day while I was tuning it in a soccer field. By the time I had gotten to the car to cut power off and inspect what was going on the 270 had blown from being at 50% brake for no less then a minute.

I ran the 270 and 590 in my last 1/8 for about 2 months before I upgraded. The throttle servo has very little stress on it when adjusted properly and will go for ages. The 590 will last a long time if adjusted properly and your servo saver is setup properly.
That being said, good servos were the best investment I ever made.

To each there own, but I have seen these fail (properly set up) over and over espescially on a track with a 35+ ft triple and a couple mean doubles.
Set up properly you can still have a bad wreck or some mean chassis flex easily take one out.
But durability aside the speed/torque on both of these servo's is laughable to use for full time racing. They are extremly slow and weak.

RTR servo's are sub par...they might get you by for a couple race's but comparing them to Hitec's and Futaba's your Kidding yourself if you think they will suffice.....spend the 200$ on Quality servo's NOW or you'll end up spending significantly more in the end....we've all been there and Done that.....there's no point in arguing how good RTR servo's are...there JUNK. :D

Hi Guys
I am about to invest in a Losi Race roller, i am currently racing a HYPER ST, so i have 2 FUTABA servos
the BLS351 and and S9157 on throttle and steering respectively.
My thinking is to just move them over to the Losi, will they be fine in this car?

This goes out to RJNicholson & TrU Integra,
Fisrt of all, RTR servos(270's & 590's) are not "JUNK".........THANKS !:D
The RTR servos are not "CRAP", "JUNK" or "SUB PAR" for that matter ! I have the 270's(throttle & reverse) & 590's(steering) both in my LST2 and I bash all the time and have never had a problem with them.;)

"Z270 Standard Race Servo is for intermediate and entry-level racers looking for a servo that offers solid reliability at a great price." - Horizon hobby
"Whether you're building your first buggy kit or looking for a reliable replacement servo for your favorite ready-to-run, the affordable Z270 is a great choice. It offers a respectable 49 oz-in of torque and solid reliability thanks to its wide spaced bearing placement on the output shaft that virtually eliminates slop. And when you consider you get all this PLUS the protection of JR's unbeatable 3-year warranty, it's easy to see why the Z270 is easily one of the best values in racing."- Horizon Hobby
http://www.horizonhobby.com/Products/Default.aspx?ProdID=JRPSZ590 - 590's
"JR's Z590M High-Torque Metal Gear Race Servo has digital steering precision for the sport driver, or those on a sport driver budget." - Horizon Hobby
"No longer do you have to be a highly-competitive racer to justify the expense of a high-torque steering servo with metal gears. JR’s Z590M Sport Torque Racing Servo provides the sport crowd with an impressive 85 oz/in of torque and a virtually indestructible solid metal gear train. Now you can beef up the steering on your ready-to-run truck or give your sport sedan laser precise steering control without leaving a major hole in your wallet." - Horizon Hobby
OR
You can go with a JRZ550 servo.

"The JR Z550 Premium Race Servo is great for modelers who want higher performance than the Z250, but don't want to pay top dollar for a high-end servo." - Horizon Hobby
"Designed specifically with the R/C racer in mind, this complete line of surface servos features shorter "race-length" leads that are a perfect fit for car and truck chassis. This saves weight and clutter and decreases the chance of outside radio interference. The servos come in standard sizes that fit any racing application, from 1/12 on-road to metal-geared, high-speed Super Servos™ for 1/8 and 1/10 scale cars and trucks. The entire JR Racing servo line is equipped with universal connectors that make them compatible with JR, Futaba, Hitec, KO Propo, and Airtronics "Z" connectors. These servos feature the same renowned JR quality hobbyists have come to expect.
The Z550 Premium Race Servo is great for modelers who want higher performance than the Z250, but don't want to pay top dollar for a high-end servo. The standard sized Z550 offers plenty of power for even the most demanding 1/10 scale gas cars and trucks." - Horizon hobby
OR
You can go with a JR650 servo.
http://www.horizonhobby.com/Products/Default.aspx?ProdID=JRPSZ650 - 650
"JR's Z650M High Torque Metal Gear Servo features a whopping 142 oz-in of torque in a standard-size case. It has metal gears for durability and a longer lead length for use in larger vehicles like monster trucks." - Horizon Hobby
"JR™ has managed to pack a spectacular 142 oz-in of torque (when used with a 6V pack) into this standard-size servo. In addition to Herculean torque, the new Z650M features metal gears and a longer connector lead for use in large vehicles. This is an excellent steering servo for monster trucks and small high-performance, high-speed boats that require maximum rudder control." - Horizon Hobby

I'm taking Integra's corner on this one. 270's and 590's are sub-crap servos. 590's I can accept for steering in a basher LST.
RJNicholson
09-28-2009, 09:22 PM
I keep seeing the "it works fine in my LST2 for BASHING".. Really??!!
That's great, but bashing is far from actual "club/series" racing.
This thread was about servo problems in a Losi 2.0T not an LST2.
Both are completely different rides. Please don't post MFG quotes. If I owned Horizon I would post that the 270 is better then a 7955 just to try and sell more. Those words only have $$$$ signs all around them. I bet you won't catch a Team Losi driver rocking a 270 & 650 at any race they ever run in.
Take that 270 apart and compare it to just a 7955 from Hitech that you take apart. The W.T.F. look on your face would be priceless.
I'm just waiting on someone to take your advice and leave the servo alone, and then post a thread called.. "W.T.F... I just blew my $300 mill cause of a $20 throttle servo!!"
Like I posted before. I have blown one of these servos just having a failsafe kick in and only be on 50% brake for no more then 1min.

09-29-2009, 10:49 AM
OMG that's some kind of funny there. Hurculean torque of 142 in/oz! Whoa, what about 333 in/oz of a Hitec or the JR9xxxxT. Seriously people, there's a difference between servo's and the 3 digit JR's are not up to the standards for 1/8th scale racing. However, UPS, FedEx or USPS may promote their use since you will keep them gainfully employed by sending them in for repair.

Hdcruzer,
It is critical that the EPA is set properly. When the linkage is set up and both the radio and Truggy/Buggy are on; remove the air filer assembly. First, Make sure that there is about 1MM of play before your throttle linkage engages. Second, apply the throttle completely. Look down the carburator and adjust your EPA so that the carburator barrel is just flush with the inside of the venturi(bottom). Third, apply the brakes completely. The throttle linkage spring should have at least 5MM of unused spring left. Now your ready to run. The additional play in your linkage is very important as the chassis flexes during use. If there is no play in the linkage, the servo motor will burn out. Hope this helps....

If you are going to spend $80, then save yourself the headache later and spend $140 for JR9100s. Set your epa correctly and use the rubber mounts. And dont over tighten the mounts, let the rubber do its job. If its in there correct, you shouldnt have any problems out of a JR.

if you want servo's that will outlast the vehicle and almost every part of it(chassis included) get 2 Hitec 7955's and forget about servo issues all together....if you ask me Fast throttle servo's(.06-.10) are overkill as most human's can even move their finger's that fast there for they are not required so .15 is Just fine for a throttle servo....Make sure to set your Epa's as 333oz of tq will break thing's before the servo gives out. :)
Any more Q's Shoot. :)

+1 for a broken throttle servo on my first run, 8T RTR. These stock servo's are junk!
Looks like I will be getting both servos to save myself the frustration I had yesterday.
I will get the 7955 for steering. Should I do the same for my throttle, or will a HS-5625MG hold up just as well? TrU Integra ?

better too much then not enough if you ask me. ;)
And its more so for the fact the board is different from the 7965/85 to the 7955...i know this by the fact Hitec states the 5955/7955 boards are 2S capable where as the 7965/85 are not....its the point of having 2 stout servo's you can use for w/e you want down the road....imo fast throttle servo's are overrated. .10-.15 is more then ample to do the job.

Dont get me wrong i use hitec servos in my truggy. I have the 7955 for steering and a hs-5625mg in for my th/br. I have yet to have a issue with either of these servos. Yes i race, yes i bash. The point is that both of these servos have lasted all season. The major factor here is do you home work on the servos. For buggy or truggies you need metal gear servos. If your using a 7955 for th/br it really is over kill. Just trying to help some of the guys here save 40 or more dollars on a servo that really isnt needed for th/br. I would not budge on the 7955 for steering. It is a awesome servo and the best i have ran with no issues.
PS: Always set your end points.

My sediments exactly !;) Dont get me wrong . On a truggy neither one of those will work for steering. You have to go top of the line . Hitec 7955 or JR 9100t. Ask me how I know. Also stay away from the 270 for throttle. You wont even get a gallon of gas through before it craps.

99.9% of the time Nothing BUT top of the line gear will last more then a couple race's....1/8 is extremely abusive on servo's both throttle and steering.....cheeping out on servo's is something you should Never do....you WILL pay for it later on down the road.

Ok True you win. I blew the 570 out in my throttle today. Made it about 3 laps and it dumped. So I ended up biting the bullitt and put a 9100s in there. So now I have a 270 a 570 and a 650 that are all garbage and have to be returned to Horizon for replacement. The other good thing about the 9100s and t is you can run lipo without a regulator.

9100s Can take it...but the life is cut in 1/2 if not more...ive seen a couple locally and heard of many online in which let go due to unregulated lipo.....Hitec on the other hand is 100% lipo ready with the 7955 or the new HV's which are 50$ cheaper then the JRHV's.....and those have been failing quite a lot recently....im personally not a JR fan if you cant tell already. :p

he's blown up a least 1 of each....and at 20-40$ each....the value spend on JUnk RTR servo's could have gotten him a Hitec 7955 and he would have forgotten about servo issues all together...guys like you that bait them into thinking a 270 or 590 is gonna cut it.....when the harsh reality of things is that RTR gear will get you started in the hobby but wont keep you running for long...its the nature of the beast...RC's expensive there's no 2 way's to look at it....doing thing's on the "cheap" normally end up with a mad user who wants to ditch the whole hobby due to some Noobie frustrations.

I normally use 590s or 650s for throttle/brake and no issues at all . And they do "cut it " . No need to buy a 200 oz servo for throttle/brake . I did use a 9100s once since it came with the buggy , but no difference in performance at all , still opened the carb and applied brakes .

The most important things is that you need to always remember to check your end points, if the servo is pulling to hard this causes extra stress on the servo and will wear it out faster. Buying higher grade servos does help but if you have the end points wrong it will take a short fall as well. proper EPA's will allow the carb to open fully with out pulling past, as well you should have play in the end of the linkage of atleast 1/32 to allow for chassis flex. on the brake side they should never pull hard enough to flex the radio tray twords the motor. I know the thinking that the harder I make the servo pull the more brakes I will have, this is not a good thought and will eat servo's.

My point is they get the job done and last if linkage and end point are properly setup .

Okay, you said to ask you , "how do you know"......so, how do you know ? & "Stay away from the '270' for throttle"......what '270', you mean '570' :confused: Heres how i KNOW. The 270 and the 590 both crapped after about a gallon and a half of gas. The 650 in the steering went bonkers wouldnt center after 4 gallons of gas. All three have been sent back to Horizon for replacement to never be used again. Just so you know end points were adjusted correctly. The track I run on, there is not one truggy left running the the cheap jrs. Reason being they all crapped. 4 of us all started wiht RTRs. Mine actually lasted longer than all the rest of them. We all run JR9100 t and s or the hitec 7955s and none of us are having sevo problems now. So Taz since these are such graet servos in your mind would be willing to buy the three I have ? If so let me know and we can work out a deal......

Ok, not here to piss off any senior people. Just sharing some info.. just picked up a RTR and My buddy has had his for a bit. He said "do yourself a favor, toss both junk servos in the trash and get hitec 7955." I said come on, well about 6 tanks in the throttle servo went just like he said. So, sinced I really only have cash for one servo right now, would it be wise to swap the steering servo to the throttle side and put the 7955 for steering? Or should I find the money to do both and be done with it.

Id replace both of them. I tried a 590 for t/b and it lasted about the same as the 270 maybe alittle longer. I never tried the 650 but I know guys who have and it crapped also. So I ended up getting the JR 9100T for steering and the JR 9100S for throttle. What a difference. There on sale at amain now for the same price as hitecs. Or you can use hitec 7955s for both holes. My track is split 50/50 either servo. I went with JRs because of the warranty which I hope I never have to use now.

you can do the swap...but think of it this way......What IF the servo takes a dump and the car goes running away at WOT lands on its lid and rev's the motor till the rod let's go..then your out a motor and a throttle servo.....and ALL because you wanted to try and save a few $$ in servo's......it very well might not happen like this....but ive seen it ALL too many time's at the track.....Cheap servo's yield cheap results....that's what i always say for the electronics controlling your 1000$ car....spend big once and forget about problems.(especially with Hitec ;))

Ya, I definatly here ya, the weather is gettin pretty bad anyway. will probably just do both and for get about it.. And ya, I got luck, throttle was only half stuck open when th servo quit!!

Well, one 7955 on and one to go. Ended up putting it on the th side then when the steering one goes I'll replace that. Had 3 workers in the LHS tell me to put it on the str side and put the jr one on the th side. But, I much rather have the steering go out then another wfo episode.. man is the hitec ever nice. feels real smooth

Fisrt off, I'm NOT a NOOB.....THANKS !!!!!;) And Second of all, your the one pushing the stupid HiTech serovs on everybody, so let everbody learn for themselves as to what they want and stop 'Baiting' them, as you so say, to buy HiTech servos......let them buy whatever they so well please to buy, unless you'd like to buy them for them !!!!!:D:p

Ive seen and personally experienced Extreme servo failure's in the past....>Ace(6) JR(4) Air(2) Futaba(3) you name it and the only one to put up to the abuse and keep coming back for more is well the Hitec Ti gear line up.....Im sorry that Taz feels so offended by me recommending a High end servo that will last more then a weekend....there's a REASON Drake and Truhe Ditched the JRHV's for the Hitec's.....they dont want any Mysterious DNF's due to Sub par servo gear's or a circuit board that just plain out quits.
your right i Should be a salesman for hitec No doubt...i would have quire the sales record. :p

Everyone has their own experiences and what works for them . Over the years I`ve used dang near every brand of servos and JR is the top for me . It`s just like Losi vs AE , AE drivers claim Losi is junk and breaks all the time and vise versa . I race with about 98% AE crowd and hear it if I break something . But it`s a different story when they break . Use what works for ya and have fun , isn`t that what this is all about ?

:cool:Got an 8ight T 2.0 RTR with about 1.5/2.0 gallons through it all track time except break in and I haven't had a problem yet. I picked up a JR 8711 though for when the throttle servo goes and I'm pretty sure it will. The 650 should be fine for throttle and the 8711 more than enough for steering. I use a 650 for the steering on my Savage "racer" (If there is such a thing...lol). And just out of curiosity why do I never hear about the 8711...whats wrong with using that?:cool:

Im the original poster of this post. Not a noob anymore. 10 races under my belt. And a couple of A-main finishes. These are not just club races. 6 of the races are a series race. Well a week after I posted this I went out and bit the bullitt and bought a JR 9100T and a 9100S while my buddy went out and bought 2 Hitec 7955s. Im happy to say im still running both with numurous hits and crashes. Cant say that about my buddy hes gone through 2 7955s. And he has now switched over to JRs also. Not a problem yet. Each to there own but Ill spend a little more and stick with the JRs

Jr servos are great and only had one with a bad top case . I`ve had nothing but bad luck with your Hitecs.

Pepsi or Coke? Does it flippin matter? Enough already with the JR/HiTec Battle. IT'S BORING!!!!! I'm sure the number of people who have had problems with either brand is fairly the same. It's all a matter of PERSONAL preferance!!!!! :mad::(:o:)
