1/2 inch boom motor mount

Made especially for 0.5inch booms is a sweet design of these motor mounts that I really love. Check out the Titan Motor Mount from Fortis Airframes: http://www.fortisairframes.com/titan-motor-mount/. This great design requires no drilling at all and will always break off in hard crashes to protect the motor. So, based on this solid plan, I made my own version specifically for 1/2 inch booms.
