I also posted this thread in the Electric Pattern forum.



This is my 2nd 6330 Pro. The first one I front mounted in a pattern plane using the conversion kit. This one is rear mounted on a motor box in a Yak 54.

It seems like it should be obvious, but without using the front mount conversion kit, the standard prop shaft is only long enough for an APC electric prop to fit without a spinner backplate. If anyone has rear-mounted this motor, how did you attach the spinner?
