Using first medium grit, and then fine, sandpa-

per, sand the both wing tips to a rounded and

tapered final shape.

49. Finish sand the entire wing surface, top and bot-

tom.

50. WORKING IN A WELL-VENTILATED AREA

and with plastic wrap or a plastic bag cover-

ing your finger, completely wrap the center

joint of the wing (top and bottom) with 2-1/2 “

nylon tape, smoothing a liberal amount of glue

into the fabric, as you go.

Cut a hole for the dowel and, when the wing is

fully wrapped, trim off any excess tape.

AILERON

1. Referring to the plan, determine the aileron cut

lines and transfer onto the bottom sheeting of

the wing trailing edge.

Then, carefully cut through the sheeting, as

shown.

2. Using a straight-edge, remove a strip of sheet-

ing between the two aft spars, as shown.

3. Using a razor saw, cut through the ribs and the

T.E., between the two aft spars, to separate

the ailerons from the wing.

Mark “top right” and “top left” on the root end

of each aileron, so that you will know which

piece fits into the left wing half and right right

wing half.

4. Trim the sheeting back flush with the aft spars

on both the aileron and the wing.

Flat sand along the entire length of the spar.
