Hi !

Are the neu 1521 size motors to big for a 3905 e-maxx ?

I'd like to have the most effichent bl system possible for max 6s lipos and topspeeds of 40mph ! and bed able to bash hard for 30-40min without overheating the system

A Neu 1521 will kill your complete drivetrain when you on the throttle the first time. I you like much power, then take a Neu 1515 and if you want a good controllable setup, take a Neu 1512.
