Top Flite TOPA0220 - Manual (Page 30)

❏ ❏ 46. Glue the top 1/16" x 1-7/16" x 24" [1.6 x 36.5
x 610mm] balsa trailing edge sheet into place with
medium CA or aliphatic resin glue. Trim the sheet
even with W1 and W10.
❏ ❏ 47. Cut, fit and glue cap strips for the top of
ribs W4 thru W10 from 1/16" x 1/4" x 30" [1.6 x 6.4 x
762mm] balsa sticks.
❏ 48. Cut the left wing plan along the dashed line
and tape it to your building board. Cover the plan with
Plan Protector or wax paper. Build the left wing panel
starting with step 10.
That completes the construction of the wing panels.
You can rough sand them now or wait until they are
joined and the center sheeting is installed.
BUILD THE WING TIPS
It is easiest to build the wing tip as a separate
assembly and then glue it to the wing. All of the tip
ribs are slightly oversize in length to allow them to
be blended and rounded at the tip. T5 and T6 are
slightly tall as well.
❏ ❏ 1. Locate a die-cut 1/16" [1.6mm] balsa wing
tip core and two each of tip ribs T1 thru T6. Place
the tip core over the plan and mark the location of all
the tip ribs.
Use the following photo for the next four steps.
❏ ❏ 2. Use thin CA to glue the parts together. Work
on one side of the tip at a time. Start by gluing T4 in
position, making sure that it is perpendicular to the
wing tip core.
❏ ❏ 3. Next, glue T2 in position, making sure T4 is
perpendicular. Refer to the plan to see how angles
are sanded onto T2 where it joins T4.
❏ ❏ 4. Glue T1 and T3 into position.
❏ ❏
5. Glue T5 and T6 into position.
❏ ❏ 6. Turn the tip over and glue a second set of tip
ribs into position.
❏ 7. Return to step 1 and build a second wing tip.
The wing tips will be glued into place during
final assembly.
BUILD THE AILERONS
❏ 1. Place the right aileron plan on your building board.
Cover the plan with Plan Protector or wax paper.
Note: All aileron parts are cut from 1/8" x 1/4" x 30"
[3.2 x 6.4 x 762mm] balsa sticks.
❏ ❏
2. Cut the aileron TE and LE from a 1/8" x 1/4"
x 30" [3.2 x 6.4 x 762mm] balsa stick and pin them in
position over the plan.
❏ ❏ 3. Cut the aileron ends from the remainder of the
stick and pin them in position. DO NOT glue until later.
