16. Center the landing gear on the fuse and drill two 1/8"
holes through the landing gear rails. Mount the landing
gear in place with the #8 x 5/8" truss head screws.

in the landing gear rails with thin CA.

18. Install the four 36" plastic outer pushrod tubes
through the guide holes in the formers until they go through
former 8 as shown on the plan. Cut the tubes so that 1" of
the tubes protrude outside the slots at the aft end.

19. Glue the tubes to the slots at the aft end of the
fuselage with microballoons and epoxy. Completely fill the
slots with the microballoons and epoxy so they can be
sanded flush later. Glue the tubes to the formers with
medium CA.

150-grit sandpaper to sand the outer pushrod tubes and
epoxy filler flush with the fuselage sides.

place with medium CA.

keep the formers perpendicular to the fuse top.
❏
2. Glue the two 3/8" x 12" balsa triangle transition
stringers to the front deck formers and the fuse top. Trim
them flush with the front of former 6.
