Great Planes Motor Mount PBY Catalina

This is a motor mount to allow using Turnigy D2830 motor in place of the much more expensive Great Planes Rimfire motor. This allows the motor to be mounted from the rear instead of the odd 3 hole front mount design used by Rimfire Motors. I suspect this can be used on other Rimfire based air frames, but it tucks nicely into the Catalina nacelles.
I have flown with these engine mounts and they did well.
