car veers to the right help plz
 

I bought a used HPI Sprint 2 and I've had to adjust a bunch of things to get it to go this far :D. Now I'm almost done but my car veers off to the right when I give it gas. I got the servo arm(not sure if thats what its called) centered as best as I could with the steering on the car, then used the setting on the Tx to fine tune it. It looks straight but the right wheel looks as if has more "toe out" than the left side but the setting are exactly the same on both sides. I spent 2 hours measuring and adjusting to make sure they are the same as the left on all the connection but I'm stumped :confused:. I'm not very knowledgable about rc cars so now its time I'm calling for some help. Also when I turn left, the right wheel rubs on the shock causing it to turn really wide....

I would post pictures but it wont let me because I don't have enough posts yet.

Send some pics to my email and ill see if i can assist you. I think i can help, just would like to see what your talking about befor i lie to you!

do you have any idea? or need more pictures?

Is there a spacer between the left wheel and the hub? If so there may need to be one on the right side

nope, no spacer on either side.

I think i can help with the veering right but im kinda stumped with the rubbing, as for as the veering goes
unscrew your servo arm, set you steering trim on you Tx to zero, turn your Tx on then your ESC, the servo will center itself, then straighten your tires up to the best your eyes can see, then install the servo arm again, then you can fine ajust it with the trim on th Tx, i hope this helps, if you get this straight it may help with the rubbing.

thanks for the suggestion. but I've already done this part, lol. I can fine tune it with the Tx and get it to not rub anymore, but then the tires aren't straight anymore...any suggestions?

heres a comparison after I adjusted it so it wont rub.

what should I adjust next?

before the adjustment(with rubbing):

after adjusting the steering on the Tx(no rubbing)

and obviously from the picture as you can imagine the veering is worse after the adjustment.

I think i should pull the right wheels toe in.. does this sound correct?

if you toe it in it will rub sooner, how about centering it up and giving each wheel about 1* toe out, you will suffer a LITTLE it in steering(it wont dive as hard) but you will get better straight line stability, try that as see if it still rubs

okay I will give that a try. Thanks for helping. Sorry but how much is "1*"? is that 1 full turn?

that should be close, mabey 2, just use good judgement if you dont have a gauge

I will give that a try, and also do you think moving the suspension in away from the wheels will have a bad effect(harder suspension) on the drive-ability of the car? It's for drifting, and in real cars you want a hard suspension for drifting. If I move the shocks away from the wheels that would eliminate the rubbing all together. I readjusted the steering again so now its almost perfect, I can go about 40 feet before it starts to veer and the tires are all straight.

You did everything right. Have you checked the EPA: End point adjustment for the left and right steering.

You've centered the servo, Centered the steering. Now you need to adjust the end point so it turns the same left and right.

The pulling might be caused by something binding on one of the output shatfts or a loose or over tight differential.
