Graham,
Sensenich do do three blades on their composite prop (or they had it in
development a couple of years ago). Probably the combined blade area
will be too great for the 912S. And the price, given what only two
blades cost.

I think its a pity Sensenich don't do three blades. Two blades always
cause yaw vibration which can't be balanced out. (due to the different
AoA of the two blades when aircraft pitch is not the same as engine
pitch, ie hi power climb) Three blades automatically balance it out.

Fred-
I'm using a Sensenich ground adjustable. I have been working with
Flight Crafters and it is their recommendation. They have installed
several with good results. It is really a pretty slick setup. The two
blades are slaved, so you only need to adjust one, and there is a small
gauge on the hub indicating the pitch.

Jim,
Would you mind letting me (us) know what prop you'll be using, and
your rationale for your decision?
Thanks,
Fred
