I'm considering a 74X38. I was told by a prop maker/Pietenpol builder/flyer that the 74/38 in front of a Cont. A65 would be my best choice. It would give me much better climb but not do much to increase speed. I'm a low and slow flyer, so I'm not concerned about increasing my speed, but really wish to increase my rate of climb. Anyone using the 74X38 with a Cont. A65? Any input anyone?

How long have you been working on it? You are too productive. Cheers, Jim Jim, I more or less committed to the Tailwind W10 project, soon after I finished construction on the Piet, in early '02. I had a serious case of 'Builders Withdraw'. Time spent on it has been on & off till about a month ago, and I really started spending a lot of time on the fuselage. The Tailwind is All About SPEED !! On 150 hp, they typically cruise around 180 mph, and can easily go over 200 mph !! I'm planning on a 'Glass Panel', too. Chuck G. NX770CG --------------------------------- Talk is cheap. Use Yahoo!

Don't know if he is still selling them or how to get hold of him anymore. I loaned mine to "Smoken Chuck" to look at. I need to get over there and pick it up before it ends up on the Tailwind! Last year there was a big discussion about the high cost of gas just before Brodhead. It was only $2.15! I thought it may be my last road trip. This year i'm going at nearly $3.00 a gal! go figure. See y"all at Brodhead Leon S. ________________________________ Message 5 _____________________________________ Time: 02:23:46 PM PST US From: "jimboyer@hughes.net" Subject: Re: Pietenpol-List: Next project - Wittman Tailwind W10 Hi Chuck, I can understand the builders withdrawal sypmtoms. after you have worked on something for several years and enjoyed it; its hard not to have somehing to work on. What was your thinking on picking the Wittman tailwind versus some of the newer designs using composite construction? I know it is very fast for the power as a local friend, Art Beer, had one for a long time, but it seems to require a lot more effort than some of the newer designs. Also since Steve had a proven Olds/Buick V8 conversion why are you using a Lycoming (probably the obvious that you had it). Your workmanship from what I can see in the photos really looks good Chuck. You are an inspiration to the rest of us.

I don't think I sent the pictures, though, because I didn't complete the one I was building...Oh well...I'll git 'er done one of these days. Leon, I've still got it here, in the package it came in. Don't worry, it won't end up on the Tailwind...way too much Drag !! The Tailwind is All about EFFICIENCY...Speed is a by-product. Chuck G.

The Tailwind has been Top Secret for years now, for that very reason...but now the cat's out of the bag !! No Worry, in an effort to get the groups permission for this next project, I'm not straying from the 'Low & Slow'. And besides, the Tailwind IS a 'Scratch Built Plane'. And also besides that, Everybody needs to have Two airplanes !! Chuck G.

Also since Steve had a proven Olds/Buick V8 conversion why are you using a Lycoming (probably the obvious that you had it). I was looking for a Fast, Economical, Scratch Built Plane. It came down to a Long EZ and the Tailwind. The Wittman Tailwind W10 fit the bill this time, but the Long EZ is going to be my next project after the Tailwind. The 'Fast Glass' planes today, are almost all Kit Planes, and I'm just not a kit builder. Before I built the Pietenpol, I designed and scratch built several very unique Radio Control Airplanes. In fact, that's where I got my screen name from...R C A P R D - Radio Controlled Air Plane Research & Development. My ol' R.C. flying buddies nicknamed me 'RD'. I would keep them entertained with some of the crazy things I brought to the field for test flights !! I still have two of them hanging from the ceiling here in my house. Steve Wittman did a tremendous amount of work to get the 215 - 265 C.I.D. Aluminum Block Inverted Olds engine to a point where it was reliable, and very few people have done it since him. There is a picture in Wittman's hanger of a bunch of guys, two of which are Bernard H. Pietenpol, Steve Wittman, as well as some other very notable characters from that time period. Bernard and Steve had very similar design philosophy's - Build it Light and Simple. They just operated at different ends of the Speed Spectrum. The Lycoming O-320 is the engine of choice for many of today's Tailwinds, and RV's because of it's reliability, and dependability. It was probably the best engine that Lycoming has ever built. I just hope I can get this Tailwind flying before Jack P. sells his RV4, which has the exact same engine I have for the Tailwind. Ya see...I bet him a Beer, that I could pass him up !!! :) Chuck G. NX770CG ________________________________ Message 9 _____________________________________ Time: 11:02:29 PM PST US From: "Gordon Bowen" Subject: Re: Pietenpol-List: Next project - Wittman Tailwind W10 Chuck, LongE plans are no longer sold by RAF, but there's plenty of good partially done stuff that occasionally shows up on E-bay, virgin set of plans with serial no. sold on Ebay year or so ago for $1500. Couple years ago, I found a partial Tailwind on E-Bay, considered it strongly instead of last Osprey project, but couldn't fit.. Re composite planes with plans, the Cozy plans are still available. Builds just like the LE but bigger and can take 0-360. Nice thing about these plans modified by Puffer from the original Rutan LE plans, is anyone who's built or worked on building other planes can actually follow the plans step by step and actually build the darn thing, unlike the plans for the Osprey and some others. Terrific support for canard-pushers via newsletters from Central States Aviators group out of Cleveland and also the canardaviators group on yahoo.
