does any of u who have the same car have the same problem ????

Doonagoowin

Can't say I have, have you tried adjusting the steering trim?

That's a sweet looking car though... How much was it?

aler_ka

lol yes i did .. i got adjustable tie rod also a aligment kit and it still ran side way@!!! ..
anyone of you think changing the chassis might help..
cause it been though alot of accident ... i just hammer it back together !!

Cypriot Boy

well the only thing i can say to you is to adjust your trim if it still inseased then check for any broken parts...

aler_ka

so what could be wrong .. i even got new metal servo.. lol !!

aler_ka

i bought that for 200, cheap if you ask me !!

Cypriot Boy

well i dont know, check your front differential, dogbones, caps.... check if everything is in its right place.

Spetz

Make sure everything moves freely
ie, all the suspension, wheels, differentials
Alignment, steering trim, belts/shafts

If everything is ok then I guess the last thing is that maybe the chassis is still bent

replace the front section.

and what pipe/header is that?

thanks nice car

aler_ka

lol i have no idea !! agian thank for the info !! i try and see what i can do ...
one more question .. does any one have rear mount exhaust on they rs4 ???

CBM Racing

Also check rear suspension arms. If one is upside down it will pull one way or the other. Another simple check, see if maybe wheel nuts are to tight holding plastic hubs against bearing to tightly causing it to bind. Also check front c-hub/axle carriers for parts on wrong side of car or upside down. I'm sure you will figure it out soon whatever it is. Good luck!

Explain how it actually goes to a side. If it seems like it's just slowly drifting out to a side, then your trim is off.
If it cuts hard, then I'm guessing one wheel isn't going at the same rate as the other.

aler_ka

its kinda hard to explain,,, seem like servo having hard time getting the wheel back into position .. no matter how i adjust it, after turning alway go side way !

aler_ka

also does anyone run a rear mount exhaust setup on they rs4 3.. i really think it would be cool to have smoke coming out from the rear not the side!!!

and i did search and found something like this "[link]http://www.tsais.com/products/exhaust/E1020R.html[/link]"

Car-Tune

Take off the springs and make sure they are all the same hight or size or damaged (if one is damaged...thats the problem)

Make sure all shocks sit on the same settings.

Make sure shock have the same amount of spacers.

Set your car on something so wheels spin freely, grab rear wheels and spin forward, look at the front wheels and see if one is not turning the same as the others, then do the same with the rear

Set your car on something so wheels spin freely, take off dogbones to each wheel, and spin each wheel and see if one doesnt spin very good.

Take off wheels, place car on flat surface, puch down on each corner, if it wobbles, then your chassis is damaged.

If none of these tips we (RC members) recomended solve your problem, Im gonna start thinking its your radio or receiver.
Borrow a friends radio and receiver, place them on your car, drive it and see what happens.

aler_ka

thankl i try that when i have time

Also check servo saver. If it has to much slop in it replace the clips or the whole thing. Also make sure you have the correct servo horn/adapter for your servo. Each brand of servo has it's own specific size and number of splines on the output shaft, so if your using say...hitec servo and the horn/servo saver is for futaba, it will not sit correctly and under stresses of driving will cause the horn/saver to slip on output shaft causing the symptoms you describe.

yo kno what it could be. it could be the steering system flexing. or something is brokien. like linkage.

aler_ka

i have stock radio (hpi tx-2) and towerpro mg995 metal gear servo

and whats ""linkage"", ""servo saver"",

aler_ka

ok !! i dont have a servo saver !!!

aler_ka

while seatting and looking at my rs4 .. i just got another stupid thought.......mounting the header down side up.. and put the exhaust to the back the car ,, and use the air filer tube... lol @!! the problem is .. putting the header up side down .. might cause the oil that cant burn going back to the engine cause damage to the engine !!

Car-Tune

Just might work, but you will have to keep your car on a high rpm so the oil wont drain back in the engine, but then you just may not even have to do that either.

aler_ka

so if the oil drain back to the engine .. will this damage the engine ???

Car-Tune

no....just shuts off

Doonagoowin

It will basically act like an overly rich engine.. Too much oil then it will bog down.
