driven by necessity, I had to find a solution to lock the canopy.
I didn't like the solution of putting a padlock on the rail so I installed a small security lock to prevent the wheel of the canopy from going past a position that allows you to put your hands inside but let in a little air when it's desired.
A small hole in the fuselage is what you see, closed by a waterproof cap.
Inside there is a glued flange and a guide tube for the key.
A cam rises and falls from a slot in the canopy rail.
If you want to give a look the link it is :
