Hi Brenner,

Of course I'm well aware the drive uses the planetary gearset and you are right I'm not thinking about a torque induced failure but the possibility of a pure bending moment being applied to the motor shaft by striking a prop either near the tip axially as might happen if you banged the prop off something while carrying the model, or during a prop strike when there will be a combined axial load on the prop tip (caused by the aircraft's forward motion) and a torque induced bending moment caused by the rotation of the prop.

And Brian, I'm well aware that Brenner and his team have been superb at identifying and sorting problems with the existing drives and I have no doubt they will do the same with this one, was just trying to make some constructive input.
