The .stl files from originally call for a stepper motor and planetary gear setup (figure 1) in order to control the roll of the glider and to be able to steer. We had challenges getting a planetary gear setup working so a change was made to use a high toque metal servo (figure 2) that was mechanically more simple, easier to program and didn't require limit switches.

The main remaining issue is keeping the coupling from accidentally separating during pitch-motor movement.
