Yes and at one point they actually had to connect the wings to meet the requirements.

Oh wow!  This is incredible.  I am sharing this info and photo with others!  

Thanks for sending guys,

Many know I am Death on the subject of "modifications". But I just now came onto some historical information that all of you may not know.

Sept. 2020 Air and Space mag explores "Racing's Fastest Biplane" noting that in 1981 at the behest of Danny Mortensen Burt Rutan  created

the Amsoil/Racer that "could almost be considered a tandem-wing design." Not just "almost" but it looked like a Quickie on steroids.

 In  the 1982 championship race, Mortensen finished second at 209.2 mph (winner's speed was 209.4). In 1983 Mortensen didn't compete in the championship

race because he "had demolished the lovely Amsoil/Rutan racer in a prior heat when he dodged an impending mid-air with Sorceress. His raceplane

hit the ground at more than 200 mph. Because Rutan had designed the cockpit to withstand a 22-G impact, Mortensen miraculously walked

away with only minor injuries".

And now you know the rest of the story.

Hi Bruce,


You can send Mike the  attached files. They are the asci files for Javafoil input that contain the geometries for BL 15 (fuselage wall), BL50 and BL100. Both the canard and the wing in the same file for each BL. The ordinates are their relative position as installed on the fuselage of the Tri-Q2, per plans. The absolute x-coordinates are in meters relative to the firewall located at 0.0 meters (FS 14 in plans) and the y-coordinates are relative to the ground (0.0 meters) for purposes of ground-effect modeling.  The plans-correct sweep and washout are also represented by the coordinates these files (LS1 canard, and Eppler Wing).  There is no anhedral, since I have modeled a Tri-Q with flat canard.


Mike can contact me offline if he has any questions. Also, may want to make him aware of my papers on the modeling, in case he is interested. Here are the links from my website:

Hi “Q Bees”!  Say Mike Shuck sent this note to me with questions on main wing and canard.  I am forwarding this to all of you to see if we can get him the correct info.  He has agreed to do a seminar on the airfoils that we have as compared to the Epley airfoil.  He will present at Field Of Dreams and you don’t want to miss it!  Leaning in your direction a bit Jay!  

Thanks guys!

Subject: Question on Canards and Main Wings


Hi Bruce,


I'm working on the the canards and main wings re: airfoils.


I have the ordinates for them but for the Q2/Q200 and the Quickie but I need to know the chord length in inches of the canards for each of the 2 models and the chord length of the main wings of each of the 2 models. If the main wings are tapered I need the maximum chord and the minimum chord in inches and I can derive the mean aerodynamic chord from that data. This way I can calculate the Reynolds numbers for each.


I hope you can help me on this. I'm going to add a canard of my own design for the Q2/200 and airfoils for the main wings of each (for theoretical uses only) just to spice up the PowerPoint presentation.


Thank you!
