Most everything I have seen is for a Corvair with the blower on top, i.e. there is a large air intake opening on the top. I am trying to design a cowling for a William Wynn conversion but don't like the boxy designs I have seen so far.

More drag, too, of course.

From: "kb2qqm" I have been searching the archives on the 3/4" versus the 1 " spar. I purchased the plans, from DP about a month ago. I got all the plans. I also got the rib template-full size with the 1" spars. I see some people are building the wing with the 3/4" spars.. (Why other than weight ?) I mounted the full size rib template, but then read on the list of the rib template differing. The new version with the 3/4" spar. Is building from the Full size rib template not a good idea? Is it accurate? I am thinking that building with the 1" spars I will have to route them. The 3/4 spars I wont ? Are the differences just a weight issue? I guess I am kind of confused between the 2 different sizes, and how it relates to the 3 piece wing I am planning to build. Comments, accusations, suggestions..welcome.

There is a coast to coast tour of "Antique and Vintage" aircraft that will fly from Comox, British Columbia to Baddeck, Nova Scotia (the home of the first flight in Canada)through the summer of 2009. The tour is stopping at every museum that is a member of the "Canadian Aeronautical Preservation Association"(including our museum. I've decided I would like to take part in the full tour with my daughter, seems to me it's one of those "life" moments and I would like to take advantage of it. The problem....what to build to fly in it? -The engine I have, built it for an aircraft I was partners in, partner had an accident, 1.6L 100hp and it's a known quantity. Swings a 70" 3 blade prop to 2750rpm no sweat. Reliable with a little over 100hrs on it. -Airframe? 2 full size adult seating(I'm 6"2", 220lbs) with dual controls Small amount of baggage (couple overnight bags) 100mph cruise Handle off field landings well 3-400 mile range plus 1hr reserve Easy to build Vintage look Top of my list, that I have done a pile of resarch on: - Heavily cleaned up Pietenpol (raised turtle deck, fairings every where, tight cowl, wheel pants) Thinking of the Riblett airfoil - 2 seat version of the Fly Baby (Plans now availabile) (cleaned up raised deck, wheel pants etc) I have access to full metal and wood working tools and a few experienced types to help out. Thoughts, suggestions?

Weight is one issue. Cost is another. Ease of fabrication is the last. They will all work. One inch spars routed out save about 16 pounds total span, as I recall reading, compared to the full 1-inch spars. That's a lot on a Piet. The 3/4 inch spars and the routed 1-inch spars are both strong enough for the Piet and its applications-- no rolls, loops, or spins. Thus the one inch spar is just extra weight. The 3/4 inch spars are cheaper than the 1-inch, and easier to fabricate and assemble than the 1-inch routed spars. The 1-inch routed spars are likely stronger than the 3/4 inch solid spars, but you are paying a premium in cost and time to achieve them. I think those are the considerations. More knowledgable people should pile on.

Good for you for stepping up to a transcontinental challenge-- 5 time zones, even. I don't have good answers, but some more questions and considerations: Have many people built the 2-place Flybaby? The Piet has a rich history, in contrast. You will find both tight with your size, but not impossible in a Piet. How about the 2-pace Flybaby... they look tiny? Re the Piet, are you thinking of putting the light bags in an enlarged turtledeck? That's the wrong place to move weight in a Piet, for CG reasons, but... you are not that heavy, and your engine weight sounds like it's more than usual for aircraft? Others will have to tell you if you can get 100 mph cruising speed in a Piet, with your engine, with Riblett foils and mucho fairings, pants, etc. Others have reported doing 85 or more in Piets, but getting tossed around a lot at those speeds. [I'd like to hear discussion on this.] With more than usual power and streamlining, and a cleaner wing, that's an interesting proposition. At 5 gallons an hour, you are talking as much as 22 gallons for your requirements. That likely means 2 tanks in the Piet-- both fuze and wing. Some may have bigger fuze tanks that allow 22 gallons. (My project allows full passenger knee room, but is maxed out at 18 gallons.) A few inches might help. If not, there goes your upper baggage space in the wing.
