Add an Aeropoxy fillet around the wooden cylinder-mounting block.
If the door wants to open too far, you can add a small scrap of wood between the cylinder
end and the bottom of the wing to prevent it from flexing upward.
Route and secure the airlines and add quick disconnects.
Repeat these steps for the other wing.
Step 13: Strut Covers
Retract the landing gear and clean the portion of the strut that the strut cover will attach to
with solvent.
Cut a piece of scrap ply approximately 10 mm wide of the appropriate depth such that it fills
the gap between the strut and the strut cover with the strut retracted and the cover in place.
Glue this piece to the strut cover with 5 minute epoxy.
Now apply Aeropoxy to the strut side of the wood piece and position the door in place. Tape
and allow the glue to dry overnight.
Extend the gear carefully and position the metal mounting bands around the strut. Drill
through the strut cover and bolt the bands in place. Use a little silicon-based glue on the
inside of the band to reinforce the attachment to the strut.

Step 14: Outer Doors
Reinforce the hinge attachment with two small button head screws. These should be
positioned at the lower part of the hinge, screwed in from the outside of the door.
You will need to attach a length of phenolic material or very thin ply to the bottom edge of
the door so it sits on top of the strut cover. This will prevent the strut cover from “catching”
on the outer door when the gear is extended.
Drill and tap the strut for a 2-56 ball link. The link is positioned in the center of the lower
strut band facing the rear of the aircraft, parallel with the outer door (photo 31).
Cut a small mounting block, approximately 5 X 5 mm, from a piece of scrap ply. Mount
another ball link. The block should be just thick enough for the link. If you make it too
thick, the outer door will not close fully.
Tack glue this assembly approximately 42 mm up from the bottom edge of the door, in line
with the ball link attached to the strut.
Make a double looped link from carbon fiber thread or thin cable. You will need to
experiment a bit, but a good starting point is a length that holds the outer door up against
the strut cover.
