How about a GSC or Powerfin? They both have better airfoils than the Warp Drive or Ivoprop, so should give results more like a custom wood prop would give. I once flew another brand of airplane using

Ron, Norm Howell built a sweet Quickie called the "Ugly Quickling" in the 80's. He set some records in it with his highly modified Onan (not fire-breathing, just intake, exhaust, and >>lotsa good cool

Ron, Save your money. Don't use that old boat anchor. It'll kill you in a Quickie and it's not even eligible for the Rotax trade-in program since it doesn't have a gearbox. You want a newer 503 with d

GJG, Have you actually been in contact with Gene Sheehan or anyone else representing QAC (or their attorneys) within the past year? David J. Gall

Diego, A Rotax 277 might have "enough" power to fly a Quickie, but you'd be challenged to fit the muffler within the cowl. The increase in horsepower over the Onan engine would be lost to increased dr

Diego, Rotax 447 or 503. Visit the files section on the yahoo group website and look for the "super Quickie conversion" .pdf. David J. Gall

Larry, Ummmm, I hope I'm misunderstanding your intent, but you don't need +3, just zero at gross weight. The +3 was a new-construction guideline to make the wheelpant attachment.... Keep up the good w

Larry, Good question! Michel Royer was the first to take my alignment advice, but he ran into difficulty getting the wheels angled within the wheel pant as much as I had suggested. He only achieved ha

Larry, Thrust is destabilizing. Camber change due to canard "bowing" under aerodynamic lift at 1 gee is approximately 40% of camber change due to canard bowing due to airplane weight fully supported b

Bob, Respectfully, I disagree. It may also be adverse yaw, but it is also something more than just adverse yaw. David J. Gall

I don't think reverse aileron steering is eliminated by setting positive camber. You still have the same flexible canard causing a difference in camber between the left and right wheels when a moment

Nicely said. You could extend this to explain "reverse aileron steering," too. David J. Gall

Doug, Jeff, Never mind asking Velocity Aircraft about these parts. Contact Scott Swing directly (through Velocity). Tri-Q parts were never part of the "Velocity business" and I'd bet that they did not

General, Your best bet is to buy Leon McAtee's redrawn CAD templates for the Q1 LS(1) canard. David J. Gall

Dan, Your second link is incorrect. The correct link is: http://www.nasg.com/afdb/show-airfoil-e.phtml?id=832 David J. Gall

LS canard: NASA LS(1)-0417MOD GU canard: Glasgow University GU25-5(11)8 Main Wing: Possibly Eppler 1230MOD, unconfirmed. IF you find airfoil performance information for any of the above, PLEASE share!

That's exactly what the Q200 is and was designed to do....

Tad, You obviously did not build your Phoenix, otherwise you would not be prefacing "I believe" in front of your pronouncements about your canard's structural material. Please take the prudent/conserv

Thanks for the update, Peter. Isn't Oz in the Conclusion Islands chain? I've jumped there so many times I think I'm starting to know the place.... Arrgh! :-) Thanks for making spars. Buy my CD and Leo

GJG- The Roncz R1145MS airfoil is not a modified LS(1)-0417 airfoil. The LS(1)-0417 airfoil is 17% thick, the Roncz R1145MS is 20.5% thick and the GU25(5)11-8 airfoil is 21% thick. Part of the beauty
