    Very sort video how it handles on track... only 450 degree setting and ~60% force:



    Wheel has max resistance of about 6kg, measured from rim. If max power is used, power supply is a bit too small, i burned 15 amp fuse while testing. Also it motor gets hot.

    On normal rallying, force is about 40-60% of max. It kicks quite enough...

    Still doing some tuning and evaluating weather this is better or worse than my 1st wheel :)
