Tricopter yaw motor mount for 10mm or 15mm boom

A rear motor mount for a tricopter. Concept based on the RCExplorer tricopter motor mount using Hobbyking steerable landing gear mounts, but with better attachment and motor mount options.

Can be bolted onto 10mm or 15mm wide booms (tested with aluminum, should be fine on wood or carbon as well), and has standard 16-19mm motor mount holes for any motor size. For use with a 3mm axle, carbon rod works perfectly.
