In need of help. my car wont drive straight
Hello everyone, I recently got into the hobby and fell in love. I have an HPI Sprint 2. When I purchased the car everything was fine. A few months went by and the car would lean towards the left then when I pull on the throttle it takes me to the right as if I'm turning right. I messed around with the trim on the remote and the turnbuckels and couldn't get it. I took it to my local hobby shop and they said try replacing the rear differential. I replaced both front and back. Still doing the same thing. I replaced the c-hubs and servo and still can't get it to go straight. So I took it again to my local hobby shop and they tried to mess with
it and even they can't get it. So at this point I don't know what els to do. The car also has a new brushless motor and brushless esc. If anyone could help me that would be greatly appreciated. Thank u in advance
