I've read many of the early Canard Pushers, a couple of hundred pages so far, and indeed they make very interesting reading! When I wrote my first posting, I was thinking specifically about the Q1 and Q2, where the original company went bankrupt, and one of the designers is deceased, so probably most of the documentation was lost. You might need to reverse-engineer the design then.
Still, I think there's still a lot of information not available publicly, that could be generated by a common effort. Just one example: the design speeds used in the design: VA, VC and VD. If you install a bigger engine, fly faster, you might exceed them. Yet I've never seen them for any homebuilt design. Same for stresses, to what stress levels is the design safe? What if you increase the mass, which happens all the time. Knowing the design work would allow a check of these questions.
