I finally got my RC10B4 up and running. After trimming out the steering via radio I noticed it's still curving to the left when I throttle. When I go full throttle the car does not go straight and I constantly have to adjust.

Could this have anything to do with the differential? I feel like the left rear wheel is spinning faster than the right which could be causing it to go left constantly.

The wheel camber seems fine. I used the camber tool that came with the RC10B4 kit and made sure everything looked correct.

Am I missing something?
