Top Flite TOPA0155 - Manual (Page 26)

Perform steps R10 and R11 only if installing
CJM gear.
❏ ❏
R10. At this time the struts must be
permanently glued into the cams with JB Weld metal
bonding epoxy. Position two plastic landing gear door
mounts (included with the CJM Top Flite Sea Fury
scale gear) on the strut so the outer door mounting
surface of the mounts is parallel with the bottom of
the wing when the gear is retracted. Use thin CA to
glue the door mounts to the struts. If necessary, glue
strips of hard balsa to the mounts, then align with the
bottom surface of the wing by sanding flush so the
gear doors will fit the bottom of the wing when the
landing gear is retracted. As can be seen in the
photo, only the top mount on this model required
building up with balsa.
❏ ❏
R11. Use a ballpoint pen and a straightedge to
mark alignment lines on the bottom of the wing across
the gear door mounts. Position the gear door on the
bottom of the wing, then drill 1/16" holes through the
doors and mounts. Mount the gear doors to the door
mounts using #2 x 3/8" [9.5mm] screws included with
this kit. Glue a strip of leftover 1/8" [3.2mm] balsa to the
inside of the gear door to add rigidity.
❏ ❏
R12. Connect the air lines to the air cylinder on the
retract. Use a retract air pump or a can of compressed
air such as Hobbico
® Duster, ™ (HCAR5500) to retract
and extend the gear. Check the fit of the wheel cover to
the wing when the wheel is retracted and fully locked.
Make adjustments to the height and positioning of the
mounting blocks so the wheel covers fit well.
❏ ❏
R13. Optional: Cut two 2-1/4" x 5-1/2" [57 x
140mm] sheets from a 1/32" [.8mm] plywood sheet
(not included). Place one of the sheets in one-half of
the opening in the wing for the wheel and draw the
outline of the cutout onto the ply sheet. Do the same
for the other ply sheets in the other side of the wheel
opening. Cut the sheets along the line, then glue
them to the bottom sheeting inside the wing. This
greatly strengthens the wing sheeting around the
edges of the wheel opening.
❏
R14. Return to step 1 and mount the other retract
the same way.
If not building flaps, proceed to “Build the outer
wing panels.”
Mount the flap servos

1. Cut a hole in the bottom sheeting along the
inside edges of the hatch supports.
