David, 

Very interesting! Thank you so much for posting! It would be interesting to see the stats on how one of these prototypes faired against the other. Historically, aircraft designed with compound curves in appropriate places do "better" than geometric, angled, boxy designs... except... well, then the Thorp T-18 and Wittman Tailwinds and BD-4's began to prove themselves. It would be cool to have a full design analysis of each prototype. 

It would be cool to locate Legare's original Q2 drawings and perform a full CFD analysis on them. <Wishful thinking>.

Thanks for posting!

Mike

Garry Legare built the boxy one without QAC knowledge or assistance. Then he
showed up at the factory and they decided he had a good idea. Legare kept
worldwide design and distribution rights, QAC got domestic US design and
distribution rights. The boxy one crashed during development for the kit.
The rebuild included the re-design with molded fuselage parts. The split-up
of design rights led to some divergence between the US version and the
version for the rest of the world; ground handling problems led to Legare
designing the T-tail and QAC designing the reflexor, hence some of the
dichotomy between US Q2/200s and the rest of the world's Q2/200s.

The prototype was built up by hand by Gary Legare in Canada, as a sort of
joint venture with QAC in Mojave. Then there was the demonstrator protoype
that was built in Mojave, which I think was N81QA (yellow), then I think
this one was further modified to become the Q-200 prototype (your photo) by
beefing up the firewall and replacing the GU with the LS1 canard. Others on
this list may know more precisely, but I think that is how it went down. All
of the regional dealers build a Q2 from a kit and used them as
demonstrators. Legare had the exclusive rights to market QAC products in
Canada in exchange for his work on the project. 

Cheers,
Jay

Hi Group,

I am curious how there came to be 2 different Q2 prototypes, the boxy one
and the beautifully sculptered one with the compound curves. Who designed
each one?

Just curious from a historical perspective.
