Ehab,

we have three up here in Seattle,one of us is ahead of the game, I'll tell him to post some pictures, he has a very simple set up for the canopy
one air cylinder to open and close,and two small servos to lock it in place....
Regards

OK. I'll post up Roberto. Here is what I came up with for mine. Thanks to Bryce for encouraging me to take the time to make the canopy functional.
I used 2 micro servos for the latches. They are mounted to the back of the cockpit tub. They move 2 4-40 threaded rods that go forward and bend up and back through brass tubes in the front windscreen frame and the front of the canopy frame. They are connected to a Jetronics sequencer and a Matchbox to synch the servos. The air cylinder that raises/lowers the canopy is actuated by a Robart valve attached to the sequencer. The sequencer is set up for "doors open" (disengages latches), "gear down" (canopy opens), "doors stay open" (latches stay disengaged), "gear up" (canopy closes), "doors close" (latches engage canopy).
It seems to be a very strong latching set-up and works reliably. The photos show the different components and the latches in both open and closed position.
I still need to clean everything up and paint some of the nicks I put in the finish, etc. so excuse the mess.
