R/C Motor Mount for 12mm Tube

thingiverse

Standard Motor Mount for 12mm tube frames. Three mounts exist, all specifically designed for 12mm OD tubes: Short two-piece clamp mount ranks as weakest of the trio, Long one-piece clamp mount holds a middle ground, while Long set-screw mount stands out as the strongest. My experience has shown that the set-screw mount provides reliability sufficient for larger (8" prop) quadcopter applications; however, this may vary from user to user.
