revo question
 

will this motor fit the rc-monster mount for the revo? http://hobbycity.com/hobbycity/store...hless_Inrunner

Nope.

45mm diameter vs 36mm on the normallt used motors.

Also, it has a 6mm shaft vs 5mm, and larger mounting screw spacing- 29mm vs 25mm.

Good motors, but you are better off with the KD45 1900kv XL motor, or a decent brand item from castle or tekin etc.
