XRAY - Model racing cars

Hi, my car is now pulling to the right when i accelerate it is awful cant make it go 1m without it going 3m sideways

Either your tires are completely wrong or the car isn't mechanically correct

Make sure all your chassis plate screws holding the bulkheads are tight. Do your wheels independently rotate freely? Do your two wheels on both axles counter-rotate smoothly? Start looking for something loose/broken

Actually given case of 1m forward and 3 sideway it is probably an awol drive shaft coupling pin if wheels/tyres are OK

Check you tweak....... Had the same problem (in little smaller scale then 1m foward and 3 sideways) and my car was really tweaked.
Do you experience this especially at starts ?

Check your chassis tweak, downstops, camber, shocks, anti-roll bars in that order! But only after you have carefully checked your tires and also tried a different tire set!
