Never mind! I found some #4 screws that I used in place of the set screws. Should work alot better.

=============================================
I bought the 1107 motor with 90mm wheels and 6mm hubs. The problem is the wheels keep falling off, the set screws keep getting loose. The allen set screws are rather weak and if you try to tighten them, they start to strip. Any suggestions?
