Quickie Q2 Lite Construction Manual - page 215
lamination should extend aft along the fuselage shell a minimum of
0.7", and should extend forward along the top of the canopy to match
the inside lamination that attached the aft canopy bulkhead to the
canopy. Grey tape is used to protect the Plexiglas and to provide a
trim edge.
.....
After cure, remove the grey tape, and trim the sides of the seal
as required to allow the canopy to open properly.
SAFETY LATCH
.....
Failure to properly secure the canopy latch prior to takeoff
will allow the canopy to open in flight. The flight characteristics
of the Q2 with a partially open canopy have not been explored. A
safety latch is assembled to prevent this potentially lethal
situation from developing.
.....
Make sure that you install this safety latch, even if you think
that "It won't happen to me".
.....
This safety latch catches the canopy in case the pilot forgets
to latch the main canopy latch prior to takeoff. To open the canopy,
raise the canopy 2" and push in on the safety latch, thus releasing
the latch and allowing the canopy to fully open.
.....
The illustration shows the construction procedures. This safety
latch is located forward of the main canopy latch, so as not to
interfere with normal operation of the main canopy latch.
