As a point of clarification, the stripped splines on one of my my KingCats occured on the JR215 heavy duty arms, NOT the mislabled standard duty arms.

My KingCats have 8611's, and I'm not really concerned with flight loads stripping the gears . I think that improper ground handling strips more gears than anything else.

That is a good reason to stay with your jets during the noon time line up, as small children and even some adults will sometimes acccidentally bump a flight control surface and ruin a gear train.
