One very close to your home Elmar ( no details on the list - call me). Usually always succesful as long as the gear is UP.

Coming from the Housai-6 and those Chinese metal blades, this has been major step up. Here is some of my experience. This is a big prop. 8 feet, 2.5 inches in length, but relatively light weight. Blade angle is critical. At 21.5 degrees, was only able to get 84% RPM on takeoff. At 17.5 degrees it gave 98% static RPM and 101% on takeoff. It was interesting to chart the increase in the max static RPM with each small change in the blade angle. Almost linear. At 17.5 degrees, full aft on the prop and throttle at 120 knots, it will go down to 56%. The blade angle is easy to adjust with the tool that comes from WhirlWind and a digital inclinometer, such as the Sears Craftsman Digital Torpedo Level. There is also a very clever iPhone 4 app that does the same thing called TiltMeter, which is equally accurate to within 0.1 degree and a lot less expensive. As expected, this is an amazing climb prop. In formation, I keep the prop between 72% and 78%, depending on how responsive I want the CJ to be. A few weeks ago on the way to a fly-in, did a side-by-side comparison with Munchie who has a CJ with the new M-14P Inc. V530C composite prop from Jill Gernetzke. From cruse power to everything forward, we both accelerated quickly, but Scott was able to pull away from me. The initial impression was that Scott's CJ with Jill's prop was also a little more responsive. At cruise, his power settings were also a little lower than mine for the same airspeed. If I had to do this again, I would seriously consider Jill's composite prop design, which is about 4 inches larger than the standard V-530 blades and 1/2 inch shorter than the Whirlwind V530-WT. I'll try to record some typical power settings at various airspeeds on the next long cross country flight.

Like Wayne Handley told me during my time with him last fall, "you're only as good as you last practice was recent...if you're lucky." In other words, don't expect to survive an engine failure unless you practice them. Doug Sapp offered up several hundred dollars of gas money for people that would go out and practice engine failures with an IP in the back. There were no takers....amazing. I fear we don't rehearse our EP's often enough, either by chair flying, or real flying. Spot landing a powerless airplane is a fun way to spend a few minutes of flying....and may just save your life.

All you need to do is purchase the Oregon Aero boom round mount electret mic, GA dual plug harness and a pair of gel ear seals. The stock PLA helmet speakers (they come still fitted inside the helmets) work just fine.

I live on Vancouver Island and we have nothing but big rocks, tall conifers and lots of water. Forced landings around here are a kind of Russian roulette. The other day I had the pleasure to meet a radial engine pilot with 26,000+ hours (who owns a very nice Nanchang as well). As far as I've understood him, I would not have the best of chances to survive ditching a CJ due the NACA cowling and the cockpit/canopy design, he rather would try to put it down in the trees. Those are merrymaking and backslapping prospects, eh? cheers Elmar ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message yak-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Yak-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/yak-list Browse Digests http://www.matronics.com/digest/yak-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
