Engineering is not witch craft or magic where you just have to believe. Engineering is data driven evidence based and must withstand all challenges. Charlie

Well said John. +/- (also known as tolerance) stacks up! The video serves as a reminder to everyone that we have to check dimensions on everything we assemble!

Did you notice that at two points the film is discontinuous? Well, that not the answer. No video trickery is involved.
With 63 squares, each square is about 1.5% of the total surface area. This makes it easy to make tiny, almost unnoticeable fudges in the area of the individual squares, and the spaces between them, which is at the heart of this 150 year old illusion….

Re: Newbie Questions
The bad thing about the Q2 built in spar is that it ends a couple of feet before the wing tips and coincidentally is where it breaks on a hard landing...

The good thing about the GU canard is that it is strong enough to not
need the carbon fibre spar. Also I understand that the contamination
issues can be solved by using VGs.

Re: Q-200 Aerodynamics Study
Jay, Now you have let the cat out of the bag, you will not be able to be the fastest Tri Q with your neutral lifting main gear legs. Regards, Charlie

I am really amazed at the data you can extract from what seems to be meaningless information. That’s why I was a jock instead of an engineer.
Keep working on the Q. J

Thanks Jerry, The videos you made with the camera beneath your vertical fin were VERY valuable to me. When I finish part 3, you will see how much I learned from your video, but basically you allowed me to figure out what the main gear leg was doing aerodynamically to affect the cruise characteristics of the Tri-Q. Quite insightful. So stay tuned. For now, you may be most interested in flipping to the latter half of part 2, for discussion of landing and takeoff behavior in ground effect. You may need the earlier half of part 2 to understand the graphs, but maybe not...after all you are a fighter jock!

Jerry,
Listen to Paul. I have never seen nicer glass work than on Paul's airplane. He pays special attention to detail, which is what gives me a fighting chance of beating him to the finish line! Cheers, Jay Scheevel, Tri-Q, still building

Re: Not so fast.
willardwhite671@...
Sam, I can't seem to post on your site, so here goes. I think you gave up too much RPM (HP). If your torque curve is flat near 3,000 rpm, you will have given up a significant amount of hp by reducing the rpm ten per cent. Your prop maker should provide you with some dyno results from a similar engine. Best results are when the prop allows the engine to spin up to max hp rpm while the tip speed approaches M.75 at 310 fps. Wouldn't it be nice if that occurred at, say 2950 to 3000 rpm? Congrats on having one of the prettiest and most efficient airplanes in the world. Keep posting on your progress. Willard

Hi Jerry
I think that Jay has answered your questions
adequately, but here are my two cents worth as an addendum.
The Waddelow (LS1) canard was designed solely
for a tri gear and must not be used as a direct
substitute canard for a tail dragger.
It is built in much the same way as the main wing,
but with extra reinforcing in certain areas. You cannot use the main wing layup
schedules to build the Waddelow canard because the canard is subject to twice
the flight loads of the main wing. The Waddelow plans address this.
It is not, of course, subject to the same landing
loads through those wingtip wheels of the taildragger, which is why the spar is
redundant.
It is built without anhedral ( i.e.flat)
which makes it easier to build.
It can be built as a standard 200" canard, as I
have, or an extended 240" version, as built and flying by Bruce
Crain.
Good luck in your endeavours
