Hmm, if thatīs true than our 5.5T are different. Higher topspeed than any 1/10 scale and about the same than a good (not top) 1/8. Lap time is just 0.2 sec slower than the fastest electric lap ever done by current WC Andy Moore during last euros at the same track. 4WD is slower on straight but has some advantage in corners.
I really donīt want that high rpm as I donīt believe bearings will work very long. Even good ones. Ceramic may be better here but will be damaged in an impact.
Next thing is the so small pinions you need for that high rpm donīt run that good and may result in higher drag. I think our motors have less rpm/more torque so we can run higher gearing.
