Top Flite TOPA0220 - Manual (Page 18)

❏ 15. Glue the top deck to the fuselage sides
between F1 and F2 with thin CA.
❏ 16. Fit former F4 into position. Note the curve of
the sides. Then, remove F4 and sand the edges of
F4 to match the curve. Glue F4 to the top deck and
fuselage sides with thin CA. Be sure that the top
deck is flush with the top edge of the fuselage sides.
Align F4 with the marks you made earlier on the
bottom of the top deck and on the fuselage sides.
Squeeze the fuselage sides together against F4 until
the CA cures.
Note: Be certain that the forward (marked) side of
F4 is facing the front of the fuselage.
❏
17. Glue the top deck to the fuselage sides
between F3 and F4.
❏ 18. In similar fashion, glue F5 and F6 into position.
❏ 19. Glue the tail end of the fuselage sides together
where they meet. Trim the top deck slightly if needed.
❏ 20. Locate two die-cut 1/8" [3.2mm] ply 1" x 2-7/8"
[25.4 x 73mm] fuse hold down blocks. Glue these
together with medium CA to form a 1/4" [6.4mm]
thick block. Using 30-minute epoxy, glue this block to
the front of F2, between the fuselage sides. Trim the
block to fit as needed. Make sure the block fits into
the cutout in the fuselage doublers.
❏ 21. Locate two more fuse hold down blocks and
glue them together. Using 30-minute epoxy, glue this
block to the rear of F3, between the fuselage sides.
Make sure the block fits into the cutout in the
fuselage doublers.
❏ 22. Locate two 1/4" x 1/4" x 36" [6.4 x 6.4 x
914mm] triangular balsa sticks. Trim them to fit along
the bottom of the fuselage sides between F3 and the
rear end of the fuselage. Glue them into position.
❏ 23. Sand the top of the fuselage lightly to remove any
glue bumps. Sand the bottom of the fuselage flat and
level. Sand the front and rear ends flat and smooth.
INSTALL THE PUSHRODS AND SERVOS
The elevator servo is installed on the left side of the
fuselage and the pushrod for that servo exits from the
right side of the fuselage.
❏ 1. Locate the two 36" [914mm] plastic pushrod
tubes. Cut one of these tubes to a length of 16"
[406mm]. Cut the remaining tube to a length of 21"
[533mm]. Save the remainder of the tubes for use
later. Use some 150-grit sandpaper to lightly
roughen the outside of the tubes.
❏ 2. Install the 16" [406mm] tube in the proper holes in
the fuselage side and formers for the elevator pushrod,
inserting it from the rear. The tube should extend 1/8"
[3.2mm] beyond F3. Install the 21" [533mm] tube in the
proper holes for the rudder pushrod. This tube should
extend 4-1/2" [107mm] beyond F3. Glue the tubes in
position with some medium CA at each former and the
fuselage sides.
