Fitting the canopy is one of the areas that people seem to dislike!
Really it’s not that difficult, and the Edge canopy is quite small,
and fits in place beautifully. Fixing the canopy to the canopy frame
can be accomplished with a good quality silicone sealant. That’s
right the same stuff plumbers use!

You may opt to use an epoxy, a plastic CA, or specialized canopy
adhesive. But be careful, CA can run, as well as fog the canopy.
Be really careful with any kind of CA kicker, discolouration and
fogging can occur. Epoxy can also be used, but it can be pretty
messy, however it is pretty affective. Canopy adhesive needs a
long time to cure, and is particularly runny.
Silicon works particularly well in this area, and provides a clear
strong bond. It is also easy to clean up and if you ever need to
replace the canopy, removing the old one is pretty straight
forward.

The clear canopy needs to be trimmed first. Start by removing the
excess material, so you can fit it over the canopy frame for
marking. The canopy can be cut with sharp scissors (If you are in
a cold climate you may need to warm the canopy before you cut.
Test a waste area first). Attach the canopy frame to the fuselage
and place the canopy over it. Move the canopy into a settled
position and mark the cut lines. Leave about 10mm over lap. Take
your time here, and make sure you are happy with the positioning
and marking.

After you have trimmed the canopy you will need to prepare the
canopy frame before you start the final fit. You need to make sure
that you sand off any high spots on the canopy frame where the
canopy will sit. Occasionally during the moulding process some
excess resin can form high spots. Also there is a fibreglass band
that runs along the middle of the canopy frame. The edges of this
band need to be smoothed. This can mostly be done by hand with
some sandpaper, but if you use a Dremel be careful not to
remove too much material. Lightly sand all the area where the
canopy will sit, then wipe clean.
