Sensenich C/S Mystery prop

I've read some posts on the web about a Sensenich lightweight electric C/S prop that is being flight tested right now. Anybody have any knowledge of this?

They may be working on a composite electric C/S prop for Rotax engines. They recently came out with a very nice looking ground adjustable composite prop for Rotax engines. The market is there and they may be jumping into it.

It seems that Eggenfellner aircraft (subaru) is working on exactly what you describe. I think one of the flying Eggenfellner powered planes is currently flying/testing one (Tom Moore?).

I'd heard that they were thinking of offering 2, 3 and 4 blade versions for engines in the 160-250hp range. Can anyone get some photos from Tom Moore of his installation and any details? Or is this still top secret? I just plunked down a big chunk for an MT.

Whatever it is, I hope it's a lot less than the MT. Quinti Avio now makes a 4-blade hub
that's good to 200hp, and Aerotek of NZ
http://homepages.ihug.co.nz/~aerotek/Prices.htm
makes a 4-blade version good to 220hp. Both come in adjustable pitch/electric CS
versions.

If Sensenich puts out something in this range, I'm set!

Sensenich has been working on a two speed prop (not CS). It was suppose to come quite a while ago but it looks like it will be quite some time before it's out, if at all. It's based on their ground adjustible prop, al hub with a composite blade.

If you have any questions about Sensenich props call Ed Z at Sensenich. He's great to deal with.

I just spoke with Sensenich (composite division) in Fl. The 3 and 4 prop electric control cs props are real. Sensenich has delivered approx. 40 of the 3 blade and 20 of the 4 blade. They ain't cheap.
$9,995 for the 4 blade.
$8,895 for the 3 blade

and $895 for the electronic controller.

Ground adjustable blades are also available.

Here's a pic of Tom with his four blade Sensenich.

The prices posted above are correct from Sensenich and Eggenfellner. Quinti hub, and the controller was designed by one of the Egg guys, I think...

This is very encouraging news, except for the price. My engine was built with a solid crank so I'd be interesting in hearing some flight reports if/when they become available. Want to unleash the full potential of my RV without putting a new engine on there.

Not a bad looking prop either!

Too bad you Lyc boys can't use the electric in-flight adjustable composite Ivo Magnum prop. It works well with most "smooth running" alternative engine, like the Subi and Rotary. http://www.ivoprop.com/inflightmagnumodel.htm

The prop is claimed to be good to 700 hp, adjustable pitch between 45"-105", and diameters between 58" and 76", weight around 25 lbs.

2 blades: $2100, 3 blades: $2340, 6 blades: $3220
