I owned a Mosquito back in the late 80s and I don't remember any springs
associated with the canopy.Â* As I recall, you simply lift the canopy up
and rotate it forward and it slides on tracks with mushroom shaped
buttons running inside the tracks.

Sorry I can't be more descriptive...

I’m building a 1-pc canopy for my HP-16 and I like the 303 Mosquito hinge method of unequal length arms. I’ve seen photos of the canopy but don’t understand what prevents the fwd hinge links from sliding fwd in the slot prematurely and striking the fuselage. Do the springs that assist in opening the canopy also pull aft and keep the fwd links at the aft end of the slot? Or, do the canopy stops that limit fwd travel wedge against something like a cam and push the links aft in the slot while the canopy is in motion?
Thanks, Brian
