This is the yaw mechanism for the ULTri Mini Tricopter.
Designed to be used with a Turnigy TGY-211DMH or BlueBird BMS-211DMH servo.
You'll need a M3x35mm screw and a M3 locknut to complete the assembly.
For maximal throws use button head screws to mount the mechanism and motor.
Please note: The holes are made 3.3mm which works great on my printer but might be too tight or loose on yours
Although designed specifically for the ULTri Mini Tricopter, this yaw mechanism will fit other multirotor arms with a 16/19mm hole pattern.
