HHINGING THE CANOPY
The canopy is hinged on the right hand side with two 6” hinges. The installation drawing gives all of the necessary details.
Remember that you previously had put in some plywood stiffeners(4) into the right side stiffener. The bolts holding the hinge to the canopy should go through these inserts. The 7” and 30” distances on the installation drawing are approximate; as you can see, the important item is for the plywood inserts to be used.
Note also that the right side longeron is carved out so that the hinge is even with the top of the longeron. Be careful not to overtorque the bolts.
CANOPY LATCH
The canopy latch is located on the left hand side.
Begin by making C3, and rounding up Cl, and C2.
Install Cl as shown. Next, take the C3 part, a batch of Bondo, climb into the cockpit, close the canopy, and position C3 on the left canopy stiffener to match the position of Cl, as shown. Hold the C3 in place until the Bondo hardens, then gently open the canopy and drill in C3. Depending on the location initially of Cl, it may be necessary to recess C3 somewhat into the plywood insert(the insert was put in when the stiffener was made).
Finally, after climbing back inside the aircraft with the canopy closE4 Bondo C2 in place so that the canopy is clamped down tight when the AN525 head is slipped into the hole in C2. Then drill C2 in place. The Macrame Bead is available from any variety store).
The canopy latch is very important. If closing the latch does not clamp the canopy down securely, you run the risk of possibly loosing the canopy in flight. Take your time and be careful.
Adjust the latch so that it snubs the rubber seal when engaged. The handle must be forced up and in to engage C2 (latch and handle rigged to preload toward each other). Thus, it is impossible to inadvertently open the canopy by bumping the handle. If you omit the rubber seal, the canopy can rattle and wear the engaging surface of Cl.
See the next page for Canopy Latch Details.
