I would expect that He would want the deep pitch version like I just switched to. But if he's finished with long trips where a high cruise speed is a big priority and is just going to be flying in the Austrian mountains, then yes this prop does have excellent take-off and climb performance. I could get off the ground in 300' (paved runway @2000'asl) and then sustain a 2400'/minute climb rate to 10000'asl. But it cruised best at a meager 120-130 mph. Top speed I ever recall seeing in level flight was 170mph. The blades are easy to cut down, and I should have done it, as It would have helped the top speed I believe, but I knew that eventually I would want to replace them with the deep pitch blades, and if they were still full length it would be easier to find a new home for them. I don't know the specs for Max's plane, but I'd suggest he do some research first as I wouldn't think they would be his best choice and he will still have to by a hub as well. And it should be the electric hub to get the most performance out of these blades. The electric CS governor is a nice addition too. If I seem like I'm trying to avoid perspective customers, I just want to be honest about it. I originally bought it used (almost new, never flown) from a former list member long ago who was being forced to sell off his project. I was still pretty naive about props back then (still am :-), but he was never dishonest, while still being pretty enthusiastic about how it would be a great prop for me. First flight was somewhat tempered with disappointment at cruise speeds, but I learned to be very happy with the climb instead. Todd - could never sell used cars!

= I=20 no longer have a need for my old prop blades. They are 76"=C3=9730-90&= quot;, left hand=20 turning. (can be cut down)=20
I'm selling without the hub as im using that with the new blades. =
=C2=A0 These are not suited for a small, fast airplane, but would be g= ood=20 for a larger slower airplane that wants a variable pitch.
=C2=A0=C2=A0=C2=A0 Unfortunately (for me)a large, slow airplane would= =20 probably also be better suited to using the RD-1C with 2.85:1 reduction whi= ch is=20 right hand turning.
=C2=A0=C2=A0 So most likely prospective buyer already has this prop an= d may=20 be interested in a few spare replacement blades.
=C2=A0=C2=A0 If someone needed these for a new install then they would= have=20 to buy the hub from IVO.
=C2=A0=C2=A0 I'm not even sure what these would be worth, so I'= ;m open to=20 offers.
