I am trying to find a steel gear for a duratrax maximum mt... anyone know of a link??? i bought this thing for $50 for a basher... ran it once and stripped 3 gears.. i run on road and am decent at meshing the gears,,, is off road different??? i know the dpro dont make one for the two speed , or maybe they do, but i can change to a single speed if need be... just want to have fun with this truck dont need top end, just dont wanna keep stripping plastic gears... any help would be great...
