Whirlwind RV-10 Prop
 

Hello all! I was just wondering if anyone out there was flying the Whirlwind Aviation RV-10 composite propeller? If you are do you have any feed back? I know plenty of people that are flying the other Whirlwind propellers and have nothing but good things to say. Thanks! Also could you post some pictures if you have them.

I looked at it for a few minutes, but the additional costs and the lighter weight did me in.

A friend of mine has one and it's slower..
 

...than my blended airfoil Hartzell two-blade by at least 7 knots, even tho' he's running 300 HP to my 260.

Best,

This doesn't mean it's related to the prop in any way though.

Pierre,
Are you sure that he is running the Whirlwind and not a MT. I have talked to a few guys running the 3 bladed MT. They are saying it is 7-10kts slower than the Hartzell. The Mt is also very pricey at $10K

Search MT props on this website. The 7-10 knots slower with the MT is old data. The MT prop for the RV-10 was a new design. I have used it on both RV-10's now, and there is no discernable difference when flying side-by-side with the other RV-10's running Hartzell's.

Vic, can you tell by looking if this is one of the newer designs ??

If not, any idea of when the change happened??

Thanks,

I think the only one you can get for the RV-10 is the new one. I couldn't help but notice the gear leg fairing and wheel pants are off on the one pictured here, so it will definitely be slower. :)

I took a 45 minute morning flight with Vic last November. We were loaded up with four adults (3 men and my wife). My prop decision was influenced at startup when I noticed how smooth it was. It was again influenced at climb out with a load of fuel and people. Cruise was smooth and fast.

Once we got on the ground I turned to Vic and said, "I've ridden in golf carts that run rougher" and I was serious.

At that point I knew I wasn't going to waste any more time researching. I had found exactly what I was hoping for. So my fwf will be a near-clone of Vic's. That composite MT was a dream.

Getting back to the original post, the new Whirlwind RV-10 prop is a two-blade model, and I would also be interested to know if anyone out there has installed one.
