Very odd to have the diff in the layshaft. The torque there is lower than at the rear axle, but the radius is equally smaller, with fewer balls to absorb the torque. I look forward to building it though. I have a 13,5T brushless that I want to use, but maybe I'll steal the 17,5T from my Ultima Pro instead. I think the recommendation of no hotter than 17,5T seems a bit conservative. My Procat has a 13,5T motor which it handles without slipping.
EDIT:
Actually, studying the build manual, the rear diff load seems to be shared by the rear axle, the spur gear AND the layshaft. There are ball bearing diffs all over the place.
