Default RE: 90sp Vs 120sp for multi blade props
Hi,

I run a Biela 18/12 (Standard blade shape) on SP120 during the last season. Prop is extremly stiff, perfectly balanced out of the package, you will be happy with the quality. The blades are broader and thicker than the APC blades. RPMs with APC are slightly higher, and I believe the top speed as well.
Have you been satisfied with the Master Airscrew? I found the blades too soft and the tracking of the blades differed about 6mm, the whole thing vibrated and did not perform well.


regards

Andi
