hinges, and then glue the doors into the fuselage.
Note: We glued the door to the fuselage with medium
CA before applying epoxy over the top of the hinge,
working the epoxy into the holes in the hinge. If you
have long grass that could drag against the doors,
you might wish to install a small bolt and nut through
the hinge and the fuselage.

11. Drill a 1/16" [1.6mm] hole in the landing gear
as shown. Mount the aluminum door spreader to the
landing gear with a #2 x 3/8" [10mm] screw.
❏
12. Locate the plywood parts shown and glue
them together as shown.
❏
13. Glue one of the smaller blocks to the gear door
just ahead of the rear door hinge. Be sure the tap is
pointed towards the bottom of the door. Do this for
both doors.
❏
14. Glue one of the larger blocks below the smaller
block approximately 1" [25mm] from the bottom of
the fuselage, making sure the tab is towards the top
of the fuselage. Do this on both sides of the fuselage.
❏
15. Glue four 1/2" [13mm] square plywood blocks
to the fuselage as shown. The doors will be pulled
down against these blocks, creating a door stop.
❏
16. Install a small rubber band to the blocks on both
sides of the doors. The rubber bands will pull the doors
shut when the gear is retracted and the door spreader
will hold them open when the gear is extended.
