Always break the same direction prop?

I've been flying multi-rotors for a few years now, and for some unknown reason, if I break a prop it always seems to be a CCW one.. I would estimate 12 out of 14 broken props have been CCW - the most common cause being landing on a slope and the multi tipping. Has anyone else experienced similar or does anyone have any kind of explanation for this??Barny

Clockwise rotating props tend to loosen the prop nut so that a cw prop striking an object tends to slip on the prop adapter.
Counter-clockwise rotating props tend to tighten the prop nuts such that a ccw rotating prop has no opportunity to slip before breakage.

Laws of Physics rule!!!
