Did some more testing on the weekend, I have to say I really like the feature, however as far as I see it, I have to change the Torque control settings based on the surface I run, i.e. if I have set the TC to a high value for high traction surface it will have too much torque/tirespin on a low traction surface.

Would it be possible to implement Traction control based on the speed the motor RPM changes? Basically that would mean to make a full acceleration run on highest traction surface (with little tirespin), then determine the maximum engine RPM change per time unit. Now let's assume on a high traction surface the motor takes 3 seconds to spool from 0 zo 30.000rpm, that would be a max. increase of 1000rpm per 0.1 seconds.

Now when driving on a low traction surface, the ESC could monitor motor RPM every 0.1 seconds and decrease throttle as soon as it detects a change in RPM greater than 1000.

What you are talking about is traction control...

And yes, we've experimented with it. It's just much tougher to implement on an RC car because the inertia of the driveline is so low...

I'll ask my engineers about it - -I know they have been doing some testing recently with similar algorithms. But I don't know the status.

Thanx!
