However, even without a load on the motor, a light tap on the end of the arm was capable of stripping the gear inside the keyang. Further investigation found that the plastic gears inside these motors have very small teeth and are easily damaged.
Just a warning...

The keyang motors aren't that powerful when compared to the others in the kit.
A FP motor (or the BB RS540, which has less power) into the 256:1 42mm gearboxes from Banebots make an easy to integrate motor with lots of torque.
Or take a hint from 968/254 (60 too maybe?) and swap you FPs into the drive to free up two small CIMs to use on the arm.
