hpi rs4 racer 2
 

hey i started using my on road car agen, i no my chassis is damn old
wen i apply full throttle it goes straight for 20 m then it starts either goin right or left :eek:
anyone no why???
i wanna upgrade my chassis to either kyosho rrr wc or serpent 720
will they handle alot better??


thanks in advance

my 18ss does the samething, I don't think it's the chassis, I think it's too much play in the stering linkage.
Remember its a rc car, not a real one, so you will go out of your mind trying to get perfect alighnment. I just deal and turn the opposite way to correct it
