manufacturing issues

The center hole on 5 of the 8 I purchased had to be filed down in order to fit onto the motors. Other than that they worked great.

Good

I have nothing bad to say about these, they are a low weight wheel hub with good tolerances and a good geometry for locking in place inside the custom TPU wheels I use on my beetle weight. For best results, use a Dremel to grind a second flat on the motor shaft to give the set screws something to grab onto, and leave a lip at the end so they can't slide off the shaft, then dump a bunch of blue loctite on the set screws so they don't vibrate loose.
