The rig is very smooth in the forward direction, but it as a bit of a twitch if I am not careful going in reverse. Between the ESC and radio, I am fairly sure I can program that out.
Fwiw...If you can't program it out, you may take a look and see if you need to add a shim between the driveshaft(s) and the pinion bearing. Seems to be fairly common on these axles.
