Default 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.

Default 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.

Default RV-10 prop

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.
