[Alan]

Hey Guys/Girls, how many people here still racing the XX4 Buggy?

Do you run saddle or stick packs?
What custom mods have you done?
Any pics of your buggy?

[jim]

I sure wouldn't mind getting my hands on one that is in good shape.

Hi Ashley, very nicely setup XX4, what are those red plates under the esc and rx?Thats not all weights is it? Yeah notice the XX4 is still very popular over there and seems most people run with the Trinity Motor mount and other Trinity goods. How are you liking the Losi motor?

[Ashley Williams]

The losi motors are awsome. THe red under the speedo and rx is heatshrinked lead 100grams in total.

[Briguy]

Since there isn`t going to be a new 4wd buggy coming out in a few days I am gonna look for a xx-4 . Where are you finding parts ?

[Alan]

Parts are still made - www.horizonhobby.com www.losipartshouse.com www.amainhobbies or anyone that deals with Losi

[Alan]

Send this guy an email if you are interested in purchasing Briguy - scottaheath@verizon.net
XX4 Worlds Edition buggy up for sale. Just rebuilt with NEW world edition chassis, NEW front graphite shock tower, NEW rear suspension arms, all other parts also graphite but lightly used. All titanium turnbuckles, threaded shocks with gold shafts, lowered motor mount plate, revised white front bulkhead with B3 brace hinge pin modification. NEW unpainted wing also.

I miss my XX-4, I got a XXX-4, had it for three races and sold it.. I curse Losi for getting rid of it. Yes I can get parts for it, but 4wd has died here so I can't see spending the money.

[Briguy]

Ok , I know it`s been a few years since I had a XX-4 , ok many . But I do not remember using the internal shock springs back then . Anyone use these ? I may have but I`d think I`d remember something like that . http://www.losipartshouse.com/servlet/the-21447/LOSA5080-Internal-Shock-Spring/Detail

i do not run the internal springs in my xx-4.

Don't use them.. all they do is end up getting jammed up and your suspension stops working right!

The best thing you can do is run it a little heavy.. add weights to it.. the XX-4 is on rails when ran on the heavy side! The only down side... and is that when you hit something.. it tends to break easier.. which as we all know is a big problem anyways.

How many people do this trick - putting a cut in the main belt cover to make changes to spur/pinion quicker and easier?

http://i30.tinypic.com/eug2om.jpg

[HeatMiser]

Not me. Isn't the need to take half the car apart to do that, or rebuild the rear diff, part of the fun? Seriously, I've seen that done, but don't care for it. As long as I have a power screwdriver, I don't mind working on the car.

[Otto]

I cut mine in three pieces, with another cut just in front of the rear diff. The slipper/pinong i rarely do anything to, but i do rebuild the rear diff often, a good thing to have done when your diff needs a rebuild before a qualifier or main.

[Alan]

Do you stick tape or something over the cut to stop dirt getting in?

[Jr. Woodchuck]

I did this, buy I ran the stronger green belt there. The car is alittle noiser on the track though.

I didn't, but I also ran on a blue grouve track that had no dust.

[Alan]

Yeah not sure why the green belt isn't in the picture as the WE came stock with green belt there. I just got that photo off oople. I decided to do it and try it out, if I don't like it will just purchase another belt cover

you will like it, alot easer to work on. Have you tried the 86 tooth spur? a little grinding is nessassery on the chassis to get it to fit. I ran a 5.5 in mine and you can ask Dustin, Matt or Lars about how crazy fast my xx4 was. I also locked up my clicker so i had insane brakes.

[Otto]

I had abit of sho-goo when running on realy dusty tracks, the top deck is not 100% enclosed from the start so there will be little difference.

[Alon]

i cut it and work wonderful i did nut put any tape. the buggy run great.
now i moved to houston and no bady run 1/10 buggy, unfortunately i gon to sale my xx4 wite ton upgerds and unique upgerds and ton new spare parts include spere old version chassis, 2 body spare. not include electricity
the price is 400$

if you interested contact me in p.m.

This little mod in my opinion is bad... sure it makes getting to he center belt easier.. but it adds a lot of flex to the chassis.

Jerome

[Alon]

i think the xx4 chassis is very stiff and the cut no make any different

[JeromeK99]

That's what I thought too... but you can flex it in your hands!

Jerome

[Alon]

i see that, but it is so small, i don't think it is got heart the stability

[Metalracer2]

I agree cutting the tunnel is not good, the buggy will not handle the same.
The buggy isn't that bad to work on if you have an electric screwdriver.

[Ashley Williams]

xx4 is easy to work on with normal allen drivers if you take the tip to tap the threads of the screws.

And i also aggree not a good idea to cut the belt tunnel.

A

[Reevsey]

if you cut the top deck you get more flex which means you will go through more belts, not to mention dirt can get in there also so i would leave alone

[Alan]

I've decided to give it ago and see how it goes - going to cut it just before the servo. If anyone knows of a Trinity Motor Clamp or Motor Mount for sale, ill be interested

[Metalracer2]

i have a trinity motor mount nip
i will try and get a pic of it later today

Congrats, any photos? It's good some god aftermarket parts on. Some people recommend to run either double shock towers or shock tower braces on really rough tracks or tracks with lots of big jumps

[Alan]

Did you buy that one on ebay? I was trying to get him to sell me the Trinity clamp and outdrives but was only an auction, was waiting for a reply back from him

[Briguy]

That is it ! I asked him if he would end the auctions early .

Yeah I just got an email from him saying he sold the aluminum parts to the buy that bought the buggy :mad: Nice buy :p Any idea what motor/esc etc. you are going to be running?

[HeatMiser]

Why is the metal motor clamp so popular? Do many guys have trouble with the stock part?

I know I'd like to find a metal bulkhead, but only if it has the right kickup. Every one I've found has been the 0deg for the Street Weapon.

[Briguy]

Some people say it is a must others don't seem to notice a difference. Some say that on tracks with lost of large jumps the motor mount can move a little on hard landings which then moves the motor and causes the spur gear to be stripped.
As for the metal bulkhead, I wasn't aware that it came out in the right kickup for the buggy, just mainly the street weapon :confused:

I guess the metal would let you sock it down more, and keep things from working loose. I guess I'll just have to keep an eye on it.

Maybe there is only one metal bulkhead. I don't know, but it would sure explain things. The problem is that the stock one isn't 0deg, so it's going to change the handling.

I`m probably gonna try the xcelorin system especially since LPH has them for $175 . Then see which I like better and decide what to put in my XXX-CR .

Anyone have any current setups for med - high bite clay tracks ? Been a long time since I drove a xx-4 and not sure where to start .

[Metalracer2]

There really is no need for a metal front bulkhead. Just put the hinge pin brace from the b3 and you should be good. I broke a front arm that bent the hinge pin and the bulkhead was still good.
A friend of mine runs the stock motor clamp with no problem, I’m not sure why everyone wants the metal motor clamp.

[Briguy]

When racing with mod motors the stock clamp tends to warp from the heat . Which eventually does not hold the motor in place that well .

[Briguy]

You guys use a B3 hinge pin brace ? Any other mods I should do ?

I've heard of this mod before, but don't know how to do it. What's the part # for that brace and where do I put it?

[Metalracer2]

I have to do some work on my xx4 so I will take some pic’s of the mod and post them.
I’m not sure what the part number is for the b3 brace but I will find out what it is

It’s pretty easy to do the mod some people shave the bulkhead but that will take away strength, I shaved the front bumper instead.
I will try and get some pics up tonight

[Metalracer2]

the b3 brace part number is ASC9120 thats the part number from Horizon hobbys wedsite
http://www.horizonhobby.com/Products/Default.aspx?ProdID=ASC9120

the pic of the bumper is after i shaved it to fit the b3 brace

[HeatMiser]

Thx for that, but those pics are too small to really see. I was poking around elsewhere and found this shot, which seems to cover the basic idea. It's not hard to see how that can help, so I''ll probably give it a shot.

[Alan]

Been looking into it and Trinity made 3 different aluminum kickups in 0, 5 & 10. (xx4 is 10). The 0 and 5 degree ones were really made for Street Weapons and they change the geometry by moving the hinge pins up about 1/8". You really don't want that on a XX4 since the front roll center is pretty high already and that just makes it worse,plus they need more kickup-not less. Either way they really aren't the hot setup for a buggy because the bulkhead was specifically designed to break before the chassis, and the aluminum bulkheads are known chassis breakers. It's not so much of an issue on sedans as they're not jumping and running on rough ground.

[Alan]

There are 3 braces you can use on the front of the XX4 - Associated B2, B3 and Losi XXX. All 3 require small tripping/cutting of the white bulkhead to get the brace to sit flush so you can put the e-clips on the hinge pin.

Picture below shows the XXXCR Brace mounted but is using XXX-CR shock shafts as hinge pins.
http://i27.tinypic.com/243gfom.jpg

[Alan]

The XXXT CR won't work only the buggy. The XXX CR brace should be easier to find than the B2/B3 and is also thicker so will probably require longer hinge pins or in this case XXX CR shock shafts. With this mod apparantly it makes the bulkhead much stronger but makes the arms a little more of a soft spot. A guy on RCTech makes front arms braces which are shown below http://www.rctech.net/forum/members/f-n-cuda.html

Front shock shafts or rears ?

[Metalracer2]

i use rear shock shaft and cut them to the right length

[Alan]

Here is some more pics and info.
This guy is using the shorter arm braces and the b3 brace for the bulkhead. He went with a XXX rear hinge pin and shortened it about a quarter inch. It clears the B3 hinge pin brace and F N cuda braces fine and is captured by the front bumper, and its long enough to almost but not quite hit the chassis.

You can do it that way, but my WE came with the Hi-Perf Blue belt (LOSA3207) up front, and the standard Green one (LOSA3206) in the middle.

[Briguy]

Mine came with the two green belts and they need to be changed .

[Y2KGTP]

are blue better than the green? Just curious on what to get.

[Metalracer2]

i run mine with the blue belt up front. if you look at the blue belt it has no strings in it so it can flex a little more

[Y2KGTP]

I think I got a plain xx-4. What is different between this, and the worlds edition?

Don't you just love impulse buys? :D

I do like the fact it does not have the NiMH cutouts.....

and a few other this where a little different

Most people run green for the front as they are stronger and can handle brushless motors better. No idea about the white belts, maybe they aren't Losi and something else that the previous owner had lying around.

I see JRX-S belts were white......prob what they were.....

[Y2KGTP]

Just curious.....does anyone think the Xfactory X5 conversion they had for the xx4 is no longer a "valid" conversion, as the efficiency of the drivetrain is not as important these days due to LiPo and Brushless motors?

aka we have more power than can be put down available with plenty of runtime....

[Ashley Williams]

X5 :( xx4 :) Long live xx4!!!!!

[xxxdad]

To me the xx-4 with the original un slotted chasi is the way to go! Long live XX-4!:cool:

[B4Maz]

Hey Guys

Alan noticed you are from Aus

ALot of people over here in the UK run the xx4 what surface are you running on i personally run stick packs down the one side of the chassis.....

Setup wise i was recomended this setup by the uk team drivers and im most situations find tit awsome on grass and astro.....

Front

Nice Ride! Did you double up your rear shock tower? Is that a brace? Where can you get one? I break shock towers all the time.

[Ashley Williams]

Hey

Cheers that version is the Xfactory E speed part

Avaliable here....

[Metalracer2]

I run the penguin braces but they are kinda thin.
I think I might try the E Speed

[Alan]

There is also the Fibre Lyte ones - http://www.fibre-lyte.co.uk/fl/cars/losi/losixx4.html

[Y2KGTP]

Is there a list of favorite modifications for the xx4 to beef it up, besides the front brace piece
between the pins? I know of several for the xxx4, but not the xx4.

[Y2KGTP]

Arugh.....I get ready to put my xx4 together tonight, and notice that it has a A & B rear bearing blocks.....installed at the same time.

More parts to order to get this thing running. :(

I'm about to go E 1/8th really soon .....

[Alan]

Yeah I have done that a few times, thought I was all good to get the thing going and then realise there is more parts I require.

[Y2KGTP]

Ok....picked up some bearing blocks so I could get this buggy together. All new belts and a few replacement pulleys along the way.

I have the cover on, just not tightened down yet. I seem to have a TON of drag trying to move the drivetrain. Will this loosen up? All the bearings are fine....I was cleaning and re-lubing them as I put this back together.

I think this is the most difficult vehicle I had to work on that I can remember. I pray it never breaks at the track, as I may just never fix it again :D

There will be some drag, but not a "ton". Wouldn't bank on it loosening up.
Which blocks did you use in the rear (A or B), and which direction are they (forward or back)?
I used the loosest combination (A - forward) and it's been fine.

I plan on switching to the A - Forward after reading the review on Oople as well. I used the Tightest combo from the start. Car is sitting 1/2 apart so will only take a few minutes to get them swapped out.


EDIT:

Uggggg......one of the steering rack bearings has a plastic bushing in it *** LOL

[Briguy]

Anyone have a part number for the 2 degree pivot blocks ? I can only find the 3 degree blocks .


Anyone know what degree these are ?

http://www.losipartshouse.com/servlet/the-21122/LOSA2210-R-Pivot-fdsh-Anti-dsh-Squat-Shims-cln-4WD/Detail

[Ashley Williams]

I use the cr one

http://www.losipartshouse.com/servlet/the-21098/LOSA2113-R-Pivot-Block%2C2/Detail

Cut out the center joining pieces its half the price for 30 seconds dremmel work.

A

[Briguy]

will the CR ones work with the xx4 axles ? I noticed the CR has the hinge pin out farther then the xx4 pivots.

[Briguy]

What are you guys running for front axles . Been having nothing but problems with stock setup . Losi make cvds for the front ? I heard the LCDs aren`t that good , this true ?

[Ashley Williams]

For belt tension i run B backwards and always have. As for front drive shafts the front CVD's from the xxx-4 fit fine. Ive also LCD's for a while now and if you build them correctly they are fine. Persoanlly i dont find the xx4 difficult to work on.

As for the cr rear pivot block simply cut out the joining braces on the block and dremel a small U shape on the pivot block to make sure the out drive doesnt catch.

[Elton]

I have seen many setup recommendations listed in this thread but none of the links seem to work, I would like to try Jukka's setup if any one has the sheets for it. Or if some one can send me a valid link to a setup for a hard packed track with lots of bumps and some big jumps.

[losidriver77]

is there any problems do the cut on the cover

[losidriver77]

where do you buy the aluminum motor mount

[Briguy]

You mean the aluminum motor clamp ? Trinity stopped making them and be lucky to find one as they are rare to find these days . I got lucky as the same guy I bought my xx4 from had some aluminum upgrades for it .

[Y2KGTP]

is there any problems do the cut on the cover

Some people state that it weakens the chassis a bit with a bit more flex. You can just put some tape over the cut line to keep dirt\dust out if needed.

I cut my old car top plate as it made it much easier to get to the spur assembly.

[Elton]

Thanks Bri I will try this out tomorrow

[Elton]

I thought the only diff. between the World and non World was that the WE came with Graphite and titanium. I recently purchased a rear pin brace and it doesnt fit but its says it fits the XX-4 WE. Is this correct?

[Briguy]

Which brace did you get ?

[Elton]

Which brace did you get ?

I got the WE brace and I only have the XX4.

[Briguy]

I got the WE brace and I only have the XX4.

LLOSA9951 will fit both .

[Elton]

Ok So I have a few questions about a setup for my recently acquired xx 4

First Question.

Which is a better investment a Lipo charger and Pack, or a Brushless motor and esc

Second question.

What type of Lipo battery should I buy?

Third question.

I have a ESC that can handle either a 8T or a 12T which would your suggest that I buy.
I am currently running the Traxxas slash 12T just because thats all the LHS had in stock (lame).

I live pretty much as far North in CA as it can get and the the ground is really hard so traction is not a problem.

Thank you for all of your help!

[Briguy]

12 brushed is a good motor for 4wd in my opinion . If I had to choose between the two , brushless , but if you can afford it get both brushless and lipo . Biggest difference .

first answer best to get the brushless system then the battery pack because you have to rebuild and maintain the brushed system alot more then a regular nimh or nicd pack

second answer if you got a lipo go with a reedy 4200 2s battery pack

third answer I would go with a 8t motor like I say it is better to have the power and control it then not have the power when you really need it

I have the reedy pack I wrote above in mine and a tekin 4.5 system in mine

[Briguy]

second answer if you got a lipo go with a reedy 4200 2s battery pack


Stay away from Reedy lipos . They never stay balanced and don`t put out a true discharge rate that they are labeled .

[losidriver77]

what do you mean I have been using mine for little over a year now and never had any problems with balancing or them staying balanced in fact I know lots of people using them and they have not had any balancing issues

[Briguy]

I have two and right from the get go both of them were way out of balance when I got them and have to balance then after 1-2 runs . My Trinity 28C , Zippy 30C , Orion 30C lipos never need balanced and are more powerful . I have heard from many others on RC Tech and at the track having similar problems .

[bshack]

Anyone have an idea on how to gear a XX-4 WE with a 7.5 motor? I have an 86 spur (purple). The motor is a Novak Ballistic 7.5. I'm gonna start at 23/86 unless anyone chimes in. Is Losi still making parts or are we SOL for factory support? I just blew the dust off of mine.. The last time I drove it was in 04'. It's the first time I've installed a brushless in it.

[Oliv996]

I've taken back from beyond my old XX4 and given it a LiPo/Brushless update: Link is here (http://forum.losi.com/showthread.php?t=1429)

I ran a 18t pinion with a 6.5, the purple spur is 84t, and red is 86t i believe. so i would think you should start with a 18 or 19t.

Ok so I have broken a few of the stock plastic bulkhead and I have seen a few of the trinity aluminum ones for sale.

Heres my Question - is it worth to spend the 30 some dollars to keep the front bulkhead from breaking? Will stronger bulkhead cause other parts to break? What do you guys run?

I would like the blue motor heat sink as well. Any one have a part # for it?

[Briguy]

The Trinity aluminum parts for the xx4 haven`t been available in a long time , they are a few and far between . I was lucky to found the motor clamp .

The aluminum bulkheads are know for breaking the chassis . You might find the parts on ebay once and a while or there is a mod floating in this thread you can do for front bulkhead .

[radar2819]

There are a bunch of parts for the xx-4 on ebay. There are also a couple of new and almost new kits to. Item number 220534438543 for a new in box one. Or item number 180453836928 that was put together and missing shocks but other than that its new and 40 dollars

[Ashley Williams]

The aluminium bulkhead is known to break the chassis. If you do insist on getting one make sure you get the 10 degree as the 0 degree is for the street weapon.

I bought my losi xx4 new back in 1997 and at the time i added all the trinity hop ups when i built the buggy.those parts are still on it and the whole xx4 is still to this day is in very good shape and very much so race wearthy. the losi xx4 is as strong now as it was way back then,it handles the track like a champ and is still very stable, and with the exciliron 6.5 brushless system its just plain wicked fast as far as that goes the 6.5 motor is just to much motor so i am considering going to the exciliron 10.5 motor which still should be plenty fast,in my opinion the losi xx4 is the best buggy losi ever made,and a race winner. so not having the lastest and greatest is not a bad thing. as for me i will stay with my old and proven winner the losi xx4 buggy.

Hey, does anyone know what company makes machined aluminum castor blocks for the XX4 buggy? I hear rumours someone does and i'm thinking this would make my front end bullet proof.

[Briguy]

Hey, does anyone know what company makes machined aluminum castor blocks for the XX4 buggy? I hear rumours someone does and i'm thinking this would make my front end bullet proof.

At the moment nobody does . Losi used to make them and Chedda Bob on RC Tech made them for a while a few years ago .

[El Scorcho]

Has anyone experienced rear belts snapping? Is there are cure? I've been running the XX4 for a couple of months now and i've snapped 2 rear belts.

I run a 6.5T motor and the car is extremely fast...but i can't afford to keep snapping belts. I have had suggestions not to run any slip in the slipper?

[Briguy]

Sounds like you need to put some slack on the rear belt . No slip in the slipper will do just the opposite , will give more shock to the belt on take off .

[El Scorcho]

Sounds like you need to put some slack on the rear belt . No slip in the slipper will do just the opposite , will give more shock to the belt on take off . i think i am running the belt too tight...local guys all run the B-bearing holder and arrows forward. to clarify what i meant is the local guys say not to run any slip in the slipper...do you disagree?

[Briguy]

Yes , I disagree . You want some slip in the slipper . The whole reason the slipper is there is to take some stress off the drivetrain .

No slippage will put even more shock to the belt you are snapping , the slipper is not the problem , the belt tension is .

[pugboy]

Definitely in my opinion run a little slip in the slipper, so it slips for about 2-3 feet should be enough, helps deal with stresses under acceleration and when landing off jumps if throttle is applied. Same thing happened to me when I first ran mine. Also, run the belt tension as described, b forward.

[El Scorcho]

thanks guys! i'm not ready to give up on the XX4 yet. This car is SO fast...it out jumps and out accerates anything i've driven before.

trial and error...we'll get it working!

[oneten]

Has anyone received a new, re-issued Worlds Edition kit that does not have the O-rings A-3218 that fit over the 3/4 inch bearings housed in the front diff case? I assume they are there as a gasket to keep the debris out. I ordered from LPH a replacement parts set: Bearing inserts and O-rings A-3217 and guess what?.......... no O-rings!!! :confused: I checked back with LPH and the remaining stock has the exact same omission, even though the part photo from Losi clearly shows the O-rings.http://www.losi.com/Products/Features.aspx?ProdId=LOSA3217

Is Losi omitting the O-rings because they are not needed anymore or are we looking at a parts supply problem? Any advice or insight would be helpful because I can't finish the car until I can get some appropriate advice, or resolution.

[oneten]

Question answered via Horizon. O-rings are not used any more over the bearing as they provide no advantage.

[mapplegate]

Ok, just got my xx4-we what gearing should I use with an 8.5?

Or should I try a 10.5? Track is only 19-20 sec lap times...thanks!

[oneten]

Try this site. I find it to be helpful to get a starting point for gearing. Of course track layout and operating temps will be a big factor also.

http://www.comeseethis.com/gearing/Default.aspx

[El Scorcho]

I've been running my XX4 for about 6 mths now and have worked through most of my issues. We have a large quad jump on our track and everyone who's fast is hitting this every lap. I've been doing it but not with consistency...and in some cases lots of carnage. My issue i'm having is i can't keep the nose down on the car :confused:

I've tried different throttling and braking in the air. The issue isn't getting the distance...it's landing it without slapping the front end down hard because the nose is skyward! My set ups have changed and mostly it's to reflect the large air needed to clear the quad.

My question is...does the clicker have any effect on the mid air flight? If i clampdown that clicker it'll be full time 4wd and i fear i will lose the awesome steering of the XX4.

Has anyone tried a one way diff * and clampdown the clicker?

*i have access to a XFactory one way.

[Briguy]

If you can`t bring the nose down when hitting the brake then add more brake to your ESC and/or radio . You should be able to adjust your nose high by applying the brake .


Your not going to achieve much by locking down the clicker and putting in a one way , still gonna be the same whether it is having the one way action in clicker or diff .


Another thing , have you added any weight to the front ? As little as a 1/2 oz can make a big difference .

Have you payed attention to how you are approaching the quad ? Usually if you can make it a few times and rest not is with how you are approaching the jump . Some jumps you can just keep on the gas , others you need to slow down and hammer it on the face of the jump , and etc. If you have plenty of brake I mess around with making different approaches and see how that goes .

I seem to have the problem after I make a stupid mistake and wreck that I tend to overpower the jumps thinking I`m going to catch up :D , which causes more crashes .

[El Scorcho]

I'll try adding some weight to the front somewhere. There's 2 of us running the XX4 here and both of us are kinda puzzled. It may just be the approach or jump face where we need to use a different set up.
Both of us have plenty of brake dialed in. My car tends to wheelie at will on the straights so today i've got the car pulled apart and i'm looking at servicing the slipper to make sure the power is transferring smoothly.
Thanks for your advice!

[Briguy]

figured I`d bring this thread back to life . :D

I got rid of my xx4 and bought a xxx-4 and was the biggest mistake . All the reasons why I stopped running it came back to me .

Needless to say the I bought another xx4 and the xxx-4 is going . Buying a xx4 that as some hard to find Trinity upgrades . Motor clamp w/ heat sink , shock bushings , shock collars , servo mount , and outdrive savers . Has aluminum caster blocks , crashback arms , Penguin shock braces , a bunch of parts , and thankfully two sets of front cvds .

Can`t wait to get it on the track !

One question for the people running XXX-CR rear arms and hubs , do the XX4 cvds still fit ?

Trevor - Look me up when you get the car or send it with your 2whl and I'll look it over to make sure things are correct. I have not run that car in ages though, nor have I run it with a lipo but I'm sure we can get you dialed in at Smac Trac. Let me know what I can do! =)

[Trevor Williams]

cool, I will have you overlook it at the track, I will ship my 2wd to you though.......

[sbanks]

Our club is goig to start running 1/10 4WD class again, so I drug out my good old XX4 to get it ready. I decided to replace the MIP front CVD's. To my surprise, they are no longer available, replaced by the new part number LOSA3228 front LCD. The pictures do not show the hex-nut that the wheel locks on to, and I don't see where you would order them separately. Am I missing something, or did they just not show the hex-nut?

Is everyone running the LCD now? How do they compare?

By the way, it looks like I have some parts for the XX4 and XXT that some of you would be interested. I will post them later.

Ya , raced mine last night !

[Carl Spackler]

Howdy Everyone,
I just picked up a bag full or parts...that at one time was an XX4. A few years ago, my buddy took it apart to fix, but never got it back together. This will be my winter project and my greatest triumph.
Any sagely advice from the good members of the Losi Forum?

Carl.

[GLAZIER]

build her slow and double check everything. got a lot of races out of mine,since last rebuild! the xx-4 wont let you down!!! i do have a fair amount of work in mine, but thats the fun part!! ill also warn you of xx-4 obsession, it is ridiculosly powerfull!!:D its pretty much all i care to race anymore!

[GLAZIER]

Ya , raced mine last night !

what class do you race with it?

im runnin 29/84 in 13.5 wheeler thats as much gear as i can pack in there! runs great and after 15min its about 140..perfect!

[Trevor Williams]

car is dialed....I am so happy with it on the track..it just has fragile front end...I fitted Schumacher cat sx arms as they are nearly identical....worked perfect all night and no more broken arms from barely brushing pipe on inside of sweeper.

[GLAZIER]

have you got a part # on those arms? would love to check that out!

[GLAZIER]

not to familliar with schumacher, is the sx the latest cat or an old one?

[smac]

The arms are off of the latest Schumacher 4wd...whatever it is called. I did not get to measure everything, but they did mount right on and they looked like they were pretty close.

Looks like schumacher may have copied geometry that every other company should have copied.

I hope Losi eventually does the same when they design a new 4wd. Maybe a shaft drive with a center diff that rotates the motor 90 deg and puts it in the same place as the XX4. Then beef up the parts and they will have the best 4wd on the market again!!

[GLAZIER]

those armes look identical,much beefier tho. havent tried them but i will. getting ready to race state champs with it this weekend!! nothin like flying past a 700 dollar durango in my thirteen year old xx-4. :p:DKICK ***! you can have my xx when you pry it from my cold dead fingers!!! :D:D

I have a XX4 (I think it's a WE but I can't remember) from way back that I want to ressurect. I haven't run it in years. I recently given a new Novak brushless control (GTB model) and motor by one of the guys at work, that I want to drop in. I think it's a Novak 5.5 velociti. Figured I would convert to Lipo as well as I don't even have any NiCd packs anymore..

I'll mainly run on the back yard track which was my RC track but became my 4 wheeler track, but it's still suitable for RC as I don't have many large jumps. No serious racing likely.

Can someone educate me on getting a Lipo pack into a XX4? I'm completely out of touch with the whole Lipo thing in general. I've seen images on here of saddles and "stick" Lipo packs. Opinions on which is easier? Custom fabrication is fine.

Also I've seen where weight was added on a couple XX4's with Lipo's, was that to bring it up to regulation weight or for weight balance?

Thoughts on gear ratios? I think the spur in there is what would have some with it. Can't remember if I had any additional ones. Thoughts on that working with typical pinion sizes.

Thanks for your help

Those Schumacher arms are identical in geometry. They have an extra hole for a sway bar attachment and they are much stronger.
I am now running the XX4 instead of my XXX4 and have been very happy with it. It seems alot stronger than my XXX so far.
It seemed like everytime the XXX landed upside down, it broke the shock tower and any hit from the front broke the inner suspension mount.

I'm so glad I found this thread...I have a lil problem I'm hoping somebody can help me zero in. I bought this sweet buggy from somebody on ebay about 6 years ago and just this past month have I been trying to use it.

Simply put, the one way clicker is clicking even when the motor is powering the wheels....didn't think that was the purpose of the clicker. This is my 1st experience with 4wd and I've never heard any other xx4s running in real life so I dunno that mine is different (I would assume that I shouldn't hear a clicking sound)? If the clicker should be noisy then no need to read on!

On the 1st run...no clicking sound, but front wheels where not turning...opened the car up and the front belt was shredded. I replaced the front belt and noticed now there is a clicking noise from the front/spur gear area only when the car was on the ground. If I throttle while holding the car, no noise. Also, I can turn the car off and roll it around manually and there is the click. I pull the motor and the click sound stops...unless I hold the spur gear while rolling it around and then it returns. I can pull the slipper assembly and the clicker appears to be working like it should...just I worry that the click is indicative of a problem that could be causing drag and tear up other parts of the car...maybe?

Sorry for the long read and thanks in advance!

Ok solved my clicker issue!

Anybody know where to get some replacement or titanium turnbuckles for the xx4? I've found several kits for xxx or xxx-cr...maybe these will work for the xx4? Anybody?

I found @amainhobbies a similar kit description but it's described as "Lunsford "Punisher" Losi XXX-4 Titanium Turnbuckle Kit" and they list part no. LNS2056. From what I can tell you linked LNS2053 described as "XX4...". Thanks for the heads-up, Briguy!
Too bad the xx4 kit is $10 higher =[

I have a set of aluminum caster blocks for sale , if anyone wants them PM me .

I noticed the blue motor mount, who makes that? And what screws do you use for securing it? The 4x40x3/8 screws that are factory recommended, the head seems to strip out very easy from over tightening. It looks like you are using a different head screw.

Trinity used to make the mounts back when the XX-4s first came out .

[lstew]

Thanks for that. I went back and read all the posts and saw that way back.

What screws are being used to hold the motor clamp down? The factory stock 4x40x3/8 cap head screws? Or different head 4x40 screws? The cap head screws seem really easy to strip, as I did Sunday at the race track. The track I race at has some pretty big jumps, so I really need to tighten that motor clamp down, and those 3/8 strip too easy.

4-40 cap head screws and never had one strip out . Are you using good hex drivers ?

[EnzoXX4]

Hello

I come from Berlin, Germany, and now I find some Time to getting my XX 4 WE together (Some guys with children know what I mean). :) I think that this forum will help me, if I have some questions for the build-up or later for the setting-up. Some pictures will follow. Sorry for my english, with best wishes.

[lstew]

Yes, using the Losi hex driver, so assuming that is good.

Ya , not sure why you are stripping them out .

[lstew]

Probably because I am really cranking them down to keep the motor from moving on the big jumps at the track.

Has anyone else used the Losi kevlar spur gears in the XX4? That's what I'm running now, and just wondering if I should switch back to the colored spur gears.

Hi

In the instruction manual for the XX 4 on tlracing.com is a gap between part I (Ends with figure 58) an part II (begins with figure 67). Is it possible to get somewhere the missing 9 figures? I think this is the section about mounting the front turnbuckles.

Thank you for help.

Anybody ever had a heard a loud creaking sound during acceleration? Sounds like it's from the tranny, but it's hard to find because it only does it when the car is on the ground. Maybe a diff is tightened incorrectly? It seems to quit once the car reaches top speed.

[jbaskew]

And well the noise pretty much persists if any time you go wide open with the throttle..so not _only_ during acceleration but also once at top speed. I was able to replicate the sound by holding the car and hitting the throttle hard for a brief moment and feathering the brakes. While doing this I put my ear as close to the tranny w/o getting my face ripped off or going def, and it really sounds like it's coming from the slipper area of the tranny.

So I took apart the xx4, and slipper is in great shape, because the pads were replaced pretty recently. The front diff is very smooth and nice and tight. The rear diff however was crunchy and would barely move just by hand.

Here's what I'm going to do:

1. replace the belts with green belts and remove the rollers
2. replace and adjust the rear diff

If the noise returns I'll try and capture the audio.

Anybody have a xx4 for sale funds are ready ??? email me at valleyraceway@aol.com

Yea...so...rebuilt the rear diff and that crazy creaking sound is gone. Though when I hit the gas full throttle from a stop it would make a quack sound, so I tweaked the diff a bit more and it sounds pretty good. This has been quite the learning experience.
