    Interesting thread. My LongEZ has a simple scissor type with over-center locking bar to keep the canopy open. In the LEZ case the latch only moves 90 were in ours it needs to go 180 but it should not be too hard to modify. Simple and works well. The canopy doesn't slam down on your head as it happens on my EU once in awhile (I actually taxy with the door partially closed held open with a small foam block).

    The best and simplest solution ever for this type of hatch can be found on the rear window of the Hillman Imp produced by Rootes Group Scotland 1961-1976; had a few for 25 years and never had a failure. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=509474#509474

    Hi Group Nev's solution with passive pins and CF reinforcement works great. I made cardboard mock up and was able to get geometry spot on. Had packaging tape on fuse and used JB KWIK Weld to temporarily hold in exact position. Then once bonded in perfect position and all is working great we then drilled fuse for screws. If alignment is not spot on friction is high and it doesn't work. It's hard to get your head around the geometry, but once you do, it works great. We did install over a decade ago and all is well. The pin and striker are made out of SS. My build partner Wayne was not convinced with my cardboard mock up. He called it a muck up! It took him till after completion of pins and striker install and actual fooling with to be convinced. Ron P.
