Also, I have had luck using eyeglass repair screws (from the little eyeglass repair kits sold at drug stores). i used two course thread screws, cut down by about 1/16 inch. If you go this route, rather than use the Like90 screws, make sure you turn the motor by hand after you intall it. If the screws are too long they will hit the armature inside the motor housing and lock it up. I don't think this would be good for it if you put power to it! Good luck!

as far as I can tell, they do that so they don't have to run the motor backwards. I find it works just as well to have it on the same side. My local hobby shop helicopter guy said make sure the prop is put on with the shiny side of the prop facing away from the motor.

The reason for mounting it backwards is to get airflow over the motor to keep it cool.
