Mike, I am almost done with my GSP Extra 300 72". I have pretty much decided just to live with having to remove the canopy every time I want to install or remove the wings. I will switch to small plastic bolts (probably 8-32) and install blind nuts on the fuselage. THis is what the author of the review article in FlyRC a few months back said he did.

I also thought about installed thin plate hinges down one side of the canopy, so I only have to remove bolts on the opposite side. Kinda like how some full size airplanes do. In any case, I think I will do away with the silly vacuum-formed "cockpit" and just install the canopy by itself.

I agree this model is designed and built very well except for the canopy attachment.
