We thought the wheel size would take awhile to speed up. (Based on preliminary tests with softball pitching machine), but the large CIM gets to speed fairly quickly.
We took off the belt tension thing and mounted the CIM flat against the plywood.

How did you mount it?
Did you drill and tap more holes?
Did you just use the mount that the tensioner lever was attached to?

We removed the pulley and used the existing stud, as well as drilling and tapping a hole in the corner that sticks out of the face.

Yes it does take the motor longer to accelerate than with lighter wheels but that wheel seems to shoot much better than the others we tested. Also, the wheel does slow when you launch a ball, but quickly regains the lost speed and you are able to shoot a ball accurately about every 1.5 s.
