I did a Glastar panel, and seeing that the landing gear
sockets would dig into my back, and the stick would be in the way in
any case, I designed the central radio stack to carry hinges on each
vertical edge, and the left and right panels were swung at this point.
Several screws along the top and bottom edges kept things closed. It
took a bit more hose and wire, and attention had to be paid to just
where you located the six flight instruments so that the outer ones
wouldn't snag the frame, but it worked like a charm and it made
finishing the airplane so easy and servicing the systems even easier.
The only visible evidence that things were different were the piano
hinges, just visible beside the radios.
