I cant find it now, but I believe I saw 30Amps for over a minute. Keep in mind that the RS775 stall current is rated at 18V as 130A. If we design for enough torque to slip wheels when pushing against a wall, the spreadsheet predicts 45A and moderate motor RPM (internal fan running). I dont think we will violate any non-smoking laws, but thats why we are trying this off season.

Any thoughts on back driving the "generator" if the ESC is in coast mode?
