    • Fit the motor and coupler to the main rotor shaft, P21

  2. Pass the 12" long, 1" threaded rods through p24 then through the tubes (not shown), through p23 and thread them through the nuts welded to the far side of P4. Attach the 4 further nuts to clamp the motor to the tubes, and the tubes against p23, in a sandwich Tighten the 2 screws in the collars of both bearings to the shaft (should be separated by 120 degrees).

    • Quality Control Checklist

    • Ensure the system rotates freely 360 degrees. If the coupler, motor and shaft are not on the same axis, it may lock up.

    • Check that when torque is applied to the motor, in either direction, there is no excessive twisting.
