Interesting. I've never experienced torque steer with an RC car, since left and right drive shafts are equal.
It's common on front wheel drive cars where motor is installed horizontally. My ex-Audi A4 with cvt transmission suffered severly from toque steer.
In short, Id have to guess that you have may have:
1. Un-even suspension set up / car is not square. Disconnect dampers, sway bars and set droop making sure it's even, then connect sway bars again to see it's even, followed by dampers
2. You may have a weight issue, causing car to pull in one direction
3. Perhaps even a bearing that is binding?
If what I wrote is pedantic, my apologies.. Just adding my $0.02 and thinking out load.
