On take off and climb, the engine is at its highest power and the airplane is usually flying slower than in cruise. Dick Martin RV8 N233M the fast one On Mon, Jun 28, 2010 at 11:12 AM, Ralph E.

Besides, the 912 IS a light sport, whic h appeals to guys like me who want to fly in the LSA=C2- category without a 3rd class medical. By rule, we can't fly at night. By the way, are you related to Edward Chalmers Huffaker? He is from my local area (Chuckey, TN) and did quite a bit of research on flight aroun d the late 1800's to early 1900's. He was with the Wright Bros at Kitty Hawk.

I've had one fail, one not leak in the tire even though it had a split when I took it apart, and I've helped several folks get rid of them by the side of the runway when theirs split a seam at fly-ins. Mostly I use flaps on take off when I'm practicing using flaps on take off... it does bring the tail up quicker, however one blows through flap speeds so quickly it is just one more thing to remember or forget. One place it is really useful is when taking off in formation with a slower plane. My first time at that was with a Lockheed L60 (think C206 mated with a Sherman tank) at KOSH. We had a plan, however I hadn't completely thought through what it meant to me in terms of throttle and speed. It was not an issue, I just wasn't mentally ready for everything to happen so slow while taking off at 1/3 throttle. Since then I've learned that some flaps do reduce the tendency to catch up too fast but one really has to 'work' at going slow enough to let the lead get airborne first. Practicing a low to medium power take off has some value because most of us have been taught to go full power in a go around. This is not needed and can exacerbate things due to the pitching up moment that occurs in our short airplanes when the throttle is slammed full at really slow speeds. Lastly, grass runways get 10 deg of flaps mostly due to the fact that the 5" tires are really small and tend to be draggy on soft or long grass. Anything that can add lift will reduce tire into sod penetration. My guess is Van's grass strip in soggy Portland has conditioned him into always using flaps.

Dale ________________________________ Message 5 _____________________________________ Time: 03:56:14 PM PST US From: "Brian Meyette" Subject: RV-List: FS: RV-7A ~80% complete I've decided to sell my RV-7A project. It's just dragged on and on, and I've lost interest in completing it. I have more interest in just flying my Challenger II. I made 75 flights in it in 2009. Engine is Subaru WRX STi 2.5 L supercharged. All the bugs are worked out of the original Eggenfellner product. Most Eggenfellner-supplied components have been replaced; SDS ECU, custom radiators, new wiring harness, supercharger gearing. Engine runs great, and all it needs is probably some more fine-tuning of the SDS ECU. John Moody in Australia has been flying his awhile. Includes latest Gen3 rev 4 PSRU, installed. Includes MT7 electric prop, installed. Three EFIS systems installed - Blue Mountain "gold box" EFIS/One, GRT Horizon, and Dynon D10. Blue Mountain AP installed. GRT EIS installed Full Garmin stack trays installed & SL-30 included. Sandia TSOd encoder, Tipup canopy completed but not final-installed. Needs rear window installed, 1 panel each wing installed, top fuse panel behind window and fwd of canopy installed (left out for wiring access). No fiberglass work done. Includes Advanced Flight Systems AoA, wig-wag HID lights, bulletproof electrical system based on Bob Nuckolls' designs and Hyperion products, low fuel warning, low coolant warning, fuel pressure warning, electric flaps, electric trim, custom console, heater, Oregon Aero seats, Hooker harness, Show Planes Flaps Positioning System, Infinity Aerospace grips, cabin lighting, custom baggage compartment and other customizations (see my custom page http://www.meyette.us/custom.htm ). Includes finishing kit and all parts (except remaining Garmin components) to finish it. All gear mounted and brakes installed. Van's front gear leg SB installed. Panel complete, except Garmin wiring. Empennage is done & final-installed. Flaps & ailerons all done. Wings not installed. And much more - this is a list off the top of my head of some of the main components. Entire project very extensively documented at http://www.meyette.us/RV-7Ahome.htm No effort or expense spared in doing everything RIGHT. Only asking $45k for it - way less than cost and making the FWF essentially FREE. Will also trade for an RV-12 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-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/rv-list Browse Digests http://www.matronics.com/digest/rv-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.
