Jim,
I don’t have a lot of time on rear mounted motors but others have been successful. Some of it comes down to bearing size and quality. I’d rather replace bearings than a broken motor mount.
John,
For this size airplane motor sizes have been for the most part standardized. My mount accommodates both sizes. I had the same concern.
Brent,
Thanks for sharing. Paul’s mount has obviously been working.
I was considering a “through the mount” style on my next version. You might have noticed the two small holes just outside the nose ring with the allen driver sticking out. That is my access point for the two top motor bolts because the spinner on the SV-11 was to small to allow clearance from the front. The rear access would fix that. So would a slightly larger spinner.
