whirlwind propellers
 

Has any one used a whirlwind constant speed prop with a lycoming io-360; and if so, how does it work?

I Have a Whirlwind 151 Three bladed on the front of my I/O 360(215hp). I have been running it for about a year and a half with 125 hours. The prop performs great! No leaks or other problems, and it looks Too cool!
Any questions, give me a call.

whirlwind
 

Thanks for the reply. I am curious about the new 200rv compared to the 151. the reason I am interested in the whirlwind is the rpm limitations and performance of aluminum props.

200RV
 

There are lots of them out there. Do a search on under this heading and you'll get good information. There is also a yahoo group for the WW props.

I have 300.92 hours on my WW 200RV now. After some initial early issues, (nothing major) the prop has been trouble free. Also, mine balanced to 0.00. This is a perfect balance.

The prop is very smooth and is specifically designed for the RV aircraft. My engine is the ECI IO360. I'm running dual Pmags. I would definitely do it again.

RE:200 RV Prop
 

I bought the 200 RV prop.......it is a real work of art!!!!!!

Check out Robbie Attaway for info and comparisons at www.attawayair.com

Frank @ SGU RV7A NDY.....but getting there

Plumb-in case you don't already know There is a RV-6A builder in Bozeman with a 200RV prop. Here's a link http://www.vansairforce.com/communit...ad.php?t=15058

plumbflyer,

Although it doesn't included the newer 151, rather the older 150, here is some info you might be interested in...
http://www.romeolima.com/RV8/Prop.htm

Check the archives, there's lots of info on the history of both the company and their products, and as others have mentioned there is a YahooGroup that is worth searching also.

Short summary...
PROS: great performance (lighter, faster, quieter), no rpm restrictions.
CONS: shorter service intervals, more expensive.

400RV Whilwind Prop
 

I have installed a 3 blade Whirlwind Prop using 3 RV200 blades. I cant report performance yet but will soon. Also planning to go to OSH. The new prop with spinner etc (complete) weighs 58 lbs. 3 blade version is 73" diam. because the 3 blade hub is a larger diam.

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.

rpm limitations

The newer -7497 BA Hartzell doesn't have an RPM limitations.

I Love Mine
 

I have a 200HP IO-360 A-1-B on my 8 and am running a WW200RV and I love it. It's smooth, looks great, performs great and the company was great to deal with. To date, after over a hundred hours on it my only complaint is one of the decals had a clear layer over it and it came off. I stopped by their booth and Sun-n-Fun and they gave me a couple new ones.
The spinner looks and fits great and is already fitted to the prop.
I have nothing to complain about at all..
