 Posted: Wed Jan 04, 2012 8:01 pm Post subject: Update on My New Whirlwind 3 Blade Prop |
 |
|
A quick update on my experience with the new Whirlwind 3 blade all composite propeller.
I have been flying this propeller on my M-14P powered CJ6-A for over three months now. Simply put – I love it!! Their first 3 blade propeller (wood/composite – I call it Generation 1) is still a great performing prop, one that I have been flying for over 10 years but this new model (Generation 2) takes the cake!! Mind you that I am not the engineer type and didn’t perform a comprehensive, scientifically correct test – I am sharing with you my findings based on my actual hands-on experience flying it… and pardon me, if I sound a little over-excited…
Needless to say, the new design is flat out gorgeous (in my opinion of course) – the large diameter of 102” and sleek, military style looks and large spinner really makes it perfectly proportioned for the CJ6/Yak aircraft…
The first thing you’ll notice, right out of the box is the amazing quality of Whirlwind’s workmanship – that is no real surprise for anyone that is familiar with their work or flying the stock V-530 propeller that they reconditioned. The finish and attention to details is incredible.
Naturally, I expected that this propeller would impress me on the very first flight as I am used to the excellent performance of their “Generation 1” propeller. Well, I must tell you – I was not disappointed… On takeoff, the acceleration was very impressive as was initial and sustained climb. One point I noticed right away was the near perfect balance and minimal vibrations through the in –flight rpm range – no dynamic balance was done at the time. The only rpm range with higher vibrations was from 1400 to 1700 rpm, a range I don’t spend much time in…
On takeoff I had to push more left rudder than I was used to – I assume it’s the greater ‘P factor’ effect due to the wider cord of this design. In cruise, the prop was smooth and response crisp at all rpm changes and flight attitudes. It is in the vertical axis that this propeller shines! Vertical penetration is noticeably better in this design as was evident to me when performing maneuvers like hammerheads and climbing rolls. A specific example: on top of a 4 G Immelman (inverted) I ended up 8 kts faster than before (same altitude, entry speed and G pull); again, not a scientific experiment – only what I’ve experienced...
Another realm in which this propeller shines is Formation. I fly a lot of formation (when not doing acro) and really enjoy the quick acceleration when I change positions or if I get sucked a bit. Deceleration is amazingly crisp as well and very useful to me in Formation when coming in with ‘gusto’ and need to slow down fast so not to overshoot Lead – this large blade acts like an air brake when quickly pulling the throttle back…
I have taken quite a few pictures ( a couple attached) and several in-flight videos of the prop and am working on making a short video clip that will be in a format of a “Product Review” and will post it on YouTube. As soon as I have the video ready on YouTube, I’ll shoot another post to let you all know J

Very nice!
What about the pricing? Comparable to the three-bladed MT prop? (also something like 102 inches).

That prop looks very nice, but is there any chance of someone doing a PROPER scientific and back-to back test against a good [ie with decent blades] V-530, and a MTV-9-29 ?? There is a place for a subjective view, but the only REAL test is to compare rate-of climb; vertical penetration; cruise and max. speed etc., and with the same pilot, weight and corrected for temperature and pressure.
