i recently bought one and put it on my bit..
i used their 2.2 motor and their gear set..
the 2.2 motor uses a white "cam"....
and for some reason it just locks up and doesnt go after a while because of well..it just does
if i spin the wheels with my hands, i can FEEL it get stuck... how the heck do i fix that to where is constantly runs?
i already tried to replace the cam with a black one, it didnt help...
i also used it on my other motors..it didnt help either...
