RE: Another Skymaster Viper
Ron,
I explained myself in a wrong way. It's not the canopy FRAME that moves, but the glass that is sucked in.
I also added two more tabs to the frame, and made a fillet of epoxy/fibers in the front and rear of the canoopy to make the frame a little stiffer.
But again, it's the glass that flexes in and out depending on the throttle setting, the frame is ok
