Forgive me, but is that not the strangest setup you've ever seen? The pinion/spur have beeb completely removed, and the motor shaft now doubles as the input shaft with the 1st/2nd input gears attached to it.....:eek: No provision for gearing adjustments but from the video/log it seems capable of 50mph and 25 minute run times using lipo.
Looking at the motor it is no longer than a 540, but it is fatter around than a BigMaxximum- wonder what the ratings are.
