Top Flite TOPA0101 - Manual (Page 12)

❏
F . Disassemble the parts and enlarge the hole
drilled in the previous step in the 1/8" plate to 1/8"
for clearance.
❏
G . Reassemble the fixed gear parts.
❏
20. Measure and drill the gear mounting holes in
the 1/4" x 5/16" x 3" plywood mounting rails .
Mount the fixed gear plates or retracts – test fit
between R-2B and R-3B while holding the 1/16"
die-cut plywood
R-3C gear reinforcement tripler in
place (if you are using retracts, make sure the
retract will clear the wing skins). Adjust the height of
R-3C if necessary. Do this for both wing panels.
❏
21. Glue the R-3C’s in position.
❏
22. Tilt the LG assemblies (fixed or retract) until
the struts protrude straight down (the left and right
struts should be parallel to each other and
perpendicular to the ground). Check the fit of the
R-2C’s, adjust their height if necessary, then glue
them in place. Glue in the mounting rails.
❏
23. Remove the LG assemblies and apply a
small fillet of 30-minute epoxy to all joints involving
plywood in the landing gear mounting areas. Apply
some epoxy to the dowel plate joints also.
❏
24. Glue all ribs to the spar. Glue both WD’s to
ribs R-1, R-2, R-3 and R-4 . Reinforce any glue
joints that appear weak.
TIP PANELS
NOTE: The tip panels are built “UPSIDE-DOWN”
on the plan (the jig tabs are attached to what is,
in the end, the TOP surface of the wing.)
❏ ❏
1. Place the tip panel plan over a flat building
board (you may wish to cut out these sections of the
plan sheet). Cover with waxed paper.
❏ ❏
2. Cut the top 1/4" x 3/8" x 20" hard balsa
spar to length. Pin it in place over the plan.
❏ ❏
3. Cut a 1/16" slot in the 3/32" balsa die-cut
ribs T-4 and T-5 between the punch marks
provided to allow the bellcrank platform to slide in
place later.
❏ ❏
4. Glue die-cut 3/32" balsa ribs T-1 through
T-7 to the spar with the jig tabs at the TE flat
against the work surface.
❏ ❏
5. Cut a V-notch in the bottom 1/4" x 3/8" x 20"
balsa spar so it can bend at T-6. Slide the bottom
spar into place. It will be glued in step 8 .
