Here are some pics of the operational servo driven canopy.

The first is a shot of a final test with cowl in place to test for clearance of my linkage. As you can see, I kust hooked the Zero up to another plane on the "flap" channel to test my canopy.
After studying for a few days, researching on the net and stuff, I read that the hardest part is getting enough control-throw to slide a canopy 3-5". I read about "sailing" winch servos and alot of air-operated pistons to drive linkage that far.
I just went with simple big arm on the old servo trick......the trick was finding room for said servo..


Servo and linkage for canopy installation is shown. Also of note is the wing in the background showing my flaps already cut and linkage routed for airelons.
