Hammbone, I went flying today with my "piped" BME110, spinning a Mejzlik 28-12 on my 40% FC330sx. It was turning in excess of 7000 rpm, and I just bolted the prop on yesterday after doing a little work to the plane. 4 flights. . ZERO slippage, and I didn't use any anti-rotation mechanisms except to put holes in the spinner backing plate, then tighten the nut on the front of the prop VERY tightly.

I'm sure you will have similar success if you just pay attention to making sure that the spinner backplate is not spinning on the hub (holes for the anti-rotation pins) and properly tighten the prop nut.

Best of luck ! ! !
