Shawn,

The Mezjlik 3 blader is quite a bit heavier than the props you are running. But you might want to try a 20x12 3 blader woodie if you can find one. I have not been able to do so. The noise will drop considerably and it should work exceptionally well in a light airframe.

If Bob's electric 3 blader doesn't pan out, I have a couple 20x12 2 blade xoar electric props that can bereshaped, cut and re-assembledas 3 blader woodie, laminated in carbon braid. Should be able to remove 2 ounces off the weight of the Mezjlik prop
