Jim=0AI 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 Guys,
I hope the Sensenich works well as I have one on order, should be
here in April.
Whirl Wind now advertise 2 and 3 blade ground adjustable props, but
the diameters appear to be more than most owners would want.

Dave and others,
I have about 100 hours on my sensenich 912-S combo. So far I can say I
love it. Easy to adjust, all bolts have never changed torque when
checked and my performance is slightly better than the warp drive that
I started with.

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'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?

FWIW, Sensenich does offer a 3 blade composite ground adjustable prop
for the 9XX designated 3BOR5R68C, weight 10 lbs., min. diameter of 64".
Alas, the shanks of the 2 blade prop they make for the Jab 3300 relies
on a different hub design and do not fit in the 3 blade-hub.

I have a pdf which apparently won't post to the list...happy to send
it to anyone who'd like to see it...the Powersweep 3 blade is indeed a
thing of beauty.
