I had an old (1996) wood core Whirlwind on which the blades had to be replaced. The wood core shrunk under the carbon fiber outer sheathing. This caused delamination. The old prop weighed 61 lbs complete.

BTW the prop is on a Glasair 1 RG, with a modified IO360C1D6 (angle valve engine 200 HP stock) producing about 245 HP at 2700 rpm on dyno. balanced blueprinted, flowed, ported, cam modified, elect ign, etc.

Some high power RV's may want to consider this prop arrangement. It does not yet show up on the Whirlwind website. They call it a 400RV prop.

It's like they read my mind! How much power is it good for?

200-260 HP is what they claim for the 400RV. I was able to reuse my original McCauley Hub. WW makes their own hub now I believe, not sure on that though.

Actually.....according to my paperwork...it's called the 400 Rocket Prop....not 'RV' Prop. As I understand....I have the 2nd one of the props that have been built.....the 1st one is on an IO-540 competition acro plane and is performing well (so I'm told).

The Whirlwind 400 Rocket Swept Tip prop is mounted on my newly minted F1 Rocket and will be flying in a couple weeks. I'll be sure to let folks know how it performs .

Can't say enough about Greg at Whirlwind!

I believe based on your photo and IO-540 HP (260-360 approx) range it is not the same. Your leading edge protection does not go as far down to the hub as the 200RV blades and how mine looks.

They call mine a 400RV on all the paperwork and manual and is for high powered IO-360.
The hub in your photo "looks" identical to mine though.

I believe mine is the 3rd of this type, RV-4 last year and a guy in Australia. Mine is the only one so far with the new style curved erosion protection at the tips just like yours has in the photo.

Default You will love this prop!

I have over 480 hours on my Whirlwind 200RV. It is smooth, fast and beautiful.

For the 200 hp engine without counterweights, there is still an rpm restriction on the hartzell ba.

Default rpm restriction on whirl wind 200RV prop!?!

I just received my 200RV prop from Whirl Wind. It is beautiful. A real work of art.

But one thing that surprised me was a statement in the manual for it that says "avoid continuous operation between 2600-2700 rpm and 2050-2300 rpm"!!!

Everything I found prior to ordering the prop indicated there where no rpm restrictions on the 200RV prop. On the specification sheet on the website, it says "restrictions: none".

So whats the deal?

Yup, this inconsistency troubled me as well. My understanding from WW is that the "avoid" statement is CYA type thing. It is not based on any testing specific to the WW prop - they adopted the statement based on testing Hartzell did on their props. I question whether that is really applicable at all, but Im no expert

In practice, you just dont hear much that is negative from people using the 200RV prop. I dont think you have much to worry about here. I dont spend much time in that RPM range anyway - do you?

Would like to hear what others have to say as well though

Default I called Greg

About this when I installed my WW 200RV. If I remember correctly he said it was the same manual as the 151 and not to pay any attention to it...

I've been meaning to mention this... Interesting isn't it? There ARE RPM restrictions on a 200RV prop. They need to either change the website or the manual...

Also, it says in the same manual that you should dynamically balance the prop before you fly it, has everyone seen that?
