Hi All,
I wanted to change my canopy lock on my RV-4 canopy frame/skirts etc from the Vans supplied method which means you "pull back to lock" shut for flight to one that is forward to lock - previous experience has always been "forward to lock" and I would like to be consistent about it. Maybe not the biggest deal but its just something that concerns me.
I have worked out how I would use a quadrant attached to the handle to change the requisite angles of the locking rods that slide through the canopy frames and lock into the fuselage structure forward and aft. The back one will work fine using the existing hole in the canopy frame. The front one is more of a problem because of the angle it is now working at -i e it runs down at about 30-40 degrees if I want to get it locking the frame near the base. If I run it straight across it will be locking the frame about 8 inches above the base and at about 30 degrees off its travel in a horizontal plane, because of the curvature of the canopy base and skirt.
I know some others have also rebuilt this mechanism to a "forward to lock" system, so I'm interested to see how you did it. Any information will be useful - ts something for me to work on while locked down from the Coronavirus.
Many thanks
Chris
