I always read up on this forum to see awesome tank builds and whenever I have questions about tanks, but this time I can't find a posted solution.

Does anybody know why my right track/motor is doing all the work during neutral steering? Left track does nothing. It can't steer while moving forward and backward.
No problem moving straight though.

What I have is a Torro Taigen Kv-2 with IBU2 Pro and Turnigy 9xr tanker9x.

Any help will be greatly appreciated.
