Here's another approach to
lifting the Legacy canopy. There is no external handle. Instead,
leaf springs are mounted inside the edge of the canopy on either side near the
lateral guide blocks (see first picture). When the canopy is lowered,
the leaf springs contact the fuselage keeping the canopy up about .75 inch
(picture 2). The dimensions and strength of the leaf springs are such
that when the canopy is lowered, the canopy latch can just engage. When
you lock the canopy down, the springs collapse (picture 3). When you
open the canopy latch, spring pressure pops the canopy up about .75 inch
(picture 4).
I have not installed the
pneumatic canopy seal yet so there could be some interference. I've been
flying with this spring arrangement for about 2 months now and it seems to
work well. I'd appreciate any feedback the group may have on possible
improvements or obvious drawbacks.

Subject: [LML] Lifting the Legacy
Canopy
Does anyone have any suggestions as to how to
install a handle or otherwise to facilitate the raising of the Legacy
canopy? It is very difficult to get it to come up the first inch or so
because there is no place to get a hold on it.
Pictures would be nice!
