Interesting.
I have a RWD 156 (but that is a scalectrix version

on my mini racetrack)
Keep in mind that the T3 diff (the center diff) from the Q4 is expecting front wheels drive too. If no torque can be transferred there, I' d be interested how it works that out, as normally it would mean it would cut the torque to the back too (which is not what you want)
