How to stop wheels spinning off their output shafts and Brushless drive

Yeah but hasn't really helped. What I might try is putting a little grease on the reverse screw head so that the washer between the wheel and the screw doesn't grip

Might sound abit basic, have you tried putting more washers on? - Defector has 6 on each side.
