Great Planes PT-60 Kit - GPMA0119 - Manual (Page 14)

D 2. Glue the left fuse side to formers F-2 and F-3.
D 3. Insert the die-cut 1/8" ply tank floor between the fuse
sides. The tab at the rear end should fit into the notch at the
bottom of F-2 and the bottom of the tank floor should fit on
top of the lower fuse doublers. Squeeze the fuse sides to
the tank floor, then glue the tank floor in position with
medium CA.
D 4. Fit the two die-cut 1/8" balsa forward fillers between
the tank floor and top doublers. The front edge of the filler
must be flush with the front edge of the tank floor and the
back edge of the doubler notch.
D 6. Test fit the die-cut 1/8" balsa aft fuse bottom
between the fuse sides. Temporarily hold the bottom in
position with a few strips of masking tape-do not glue yet!
D 7. Install the die-cut 1/8" ply formers F-4 and F-5 in the
notches of the fuse sides and bottom. Be sure that the
antenna tube hole is toward the bottom of the fuse. Use
more masking tape to hold the formers tightly in position.
When you are satisfied that everything looks square and
true, place the fuse on a length (at least 36") of waxed
paper, then wick thin CA into the joints (from the inside)
between the fuse sides, bottom, and the formers. Press
down on the framework as you do the gluing to hold the
frame square.
D 8. Apply medium CA along all inside joints to
permanently secure the framework.
D 9. Cut one of the 36" plastic outer pushrod tubes to
32". This will be used for your antenna tube. Cut two more
pushrod tubes to 30". These will be used to contain the
elevator and rudder pushrods.
D 5. Test fit the die-cut 1/8" balsa front fuse bottom into
the notches and recess on the bottom of the fuse. When
satisfied with the fit, wick thin CA along both outside edges.
Turn the fuse over, then wick thin CA into the inside joints
between the bottom and the formers. Follow with medium
or thick CA in any open joints.
D 10. Lightly sand the outside of the pushrod tubes with
150-grit sandpaper to make them "receptive" to glue. Slide
the 32" antenna tube through the bottom hole in formers
F-3,F-4 and F-5 all the way to the tail. Slide the other two
pushrod tubes through the upper holes in the same
formers and out through the exit slots at the rear of the
fuse. These tubes should protrude about 1/2" past the
rear end of the slots.
D 11. Use medium CA to glue the pushrod tubes to each
former and the inside of the exit slots.
