Steve,

I used a rear support on the Advance in my Nuance. I lost the bolts on a flight and there was a efinite increase in sound level and some strange noises. Replaced the bolts and was back to normal. I would definitely recommend a rear support.
For the front mount I used Chris' mount as a template for 3/32 plywood, reinforced by carbon mat and epoxy. The correct diameter is through the screw holes as you can see in the photo. For the rear mount I braced the recess in the back of the motor. There should be pictures.
