Wheels Keep Falling Off

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?



It’s good to hear you figured out a solution. With the stock units stripping, are you talking about the threads, or are you talking about the socket for the allen wrench?

One thing you could do is look at where the set screws hit the motor shaft and add some little holes there. Also, did you try threadlock on the screws?
