Hi WhirlWind,
Just installed your new 70in S.T.O.L. propeller on UL350 powered Zenith 701. I can say with confidence this is the best performing propeller we have tried, and we have tried them all! Take off and climb are impressive and everyone is crazy over the carbon fiber finish.
Thanks for a fantastic propeller !!

We flew for 4 hours with the new Whirl Wind 3 blade propeller for the UL 350IS and I must say I am impressed. 3300 RPM for takeoff and the propeller would out climb the “Brand X Propeller”, however the cruise RPM was too high. So that we added 2 degrees of pitch and could take with 3000 RPM, the rate of climb was still 1400 feet per minute. Now I cruise with 100 less RPM than the “Brand X” at 96 MPH and 2560RPM. This is the best preforming propeller we have tested. And we’ve tested all the big name brands.
Here are Pictures of our new UL 350 3 blade Whirlwind propeller during the partial solar eclipse. Fitting because this prop has eclipsed all the others we have tested so far.

“Attached is a photo of my airplane with your GA200L prop installed; purchased in Feb 2011. Engine is a Superior XP-360, yielding top cruise speed of around 160 mph. I love this prop! Compared to Sensenich aluminum fixed pitch it results in 20 lbs less weight and 5 mph faster!”
