Tricopter Motor Tilt

thingiverse

This is my version of a tricopter tilt mechanism, built around a Turnigy TGY-210DMH servo that will fit any servo of the same size. The servo is elevated 5mm above ground, so you won't need to cut out parts of it. You'll need four small zip-ties to secure the bottom part to the arm and one bigger zip-tie for the servo. The strong small bottom part can hold the motor, while the servo holder only counteracts the steering torque. I've updated the servo holder with holes for smaller zip-ties. There's just one universal motor holder that fits all variants, which requires a M3-30mm axle and a 30mm screw that perfectly matches the updated design. Be sure to leave some extra space between the motor and servo by making it slightly asymmetrical. Keep the servo in middle position and tighten the screw to secure it in place, but avoid over-tightening. This tilt mechanism was inspired by David Windestal's from rcexplorer.se, but since I didn't have a M3-40mm axle, I created my own version. The updated design now works with 10 mm, 12.5 mm, or 14 mm arms. Update September 2016: There's a new motor holder that requires a servo arm, which needs a single-side arm with two holes on 10mm and 15mm. Two small screws (10mm long) come with your servo to fix the servo arm in place. I also created another version with a splined servo mount, but my printer isn't able to print it in a usable way, so you can use the 'servohorn' version if the universal tilt motor without splines doesn't work for you.
