I've got a functional canopy installed on my Yellow F-18 DF.

I used 2 Century Jet air cylinders to open and close the canopy. They are hooked up to a reduction valve to slow the opening and closing to about 5 seconds.

As for a canopy lock, I'm using a small flexible throttle cable to lock the canopy down in the front. In order to ensure its locked, I've got the cable hooked up to a searchlight and 9V battery. So if the lights on the canopy is locked! I've also got a intermediate postion to lock the canopy and not drain the battery.

Alignment of the hinges and canopy was the biggest pain in the butt.. But when it works it's way cool..

GOod luck
