I would second this. In our shooter design, we've moved the wheel off of the motor itself in order to provide a more stable mount for both. Besides, with the wheel on the motor, isn't is awkward to replace the motor if it fails?

Side note: We actually had started with the wheel on the hub on the motor shaft and mounted the motor to a plate using the front-side mounting holes so thoughtfully provided. It got interesting about 2 hours of testing later when one of those bolts backed out because of the vibrations ... Replacing that bolt required removing the wheel ...
