Perform these steps only if you are installing
retracts.
CUT OUT THE WHEEL WELLS
Start by cutting and removing just
enough sheeting to mount the landing gear to the
rails.
2. Retract the gear to the wing and draw a
rough outline of the wheel onto the sheeting. Cut
the sheeting within the outline. Retract the wheel
again and draw a more accurate outline. Cut the
sheeting until the wheel fully retracts into the
wheel well, leaving at least clearance
between the wheel and the sheeting (in case you
tweak your landing gear on one of those
bumpy landings).
BUILD THE WING TIPS
Cut the molded clear plastic right wing tip
lens along the cutlines. If you are installing the
optional lighting kit, drill holes in the die-cut
balsa tip lens rib
for the lighting wires to
pass through.
2. Align with so the edges of the
lens are flush with the wing sheeting. Glue to
W14 in this position.

3. Glue the die-cu t 1/8 balsa aft lens rib
WT1 to the aft edge of WT14 Position the 1 1/2" x
2 1 / 8 x 6" balsa wing tip block on the wing tip and
trace the outline of the wing onto the block.

4. Read the note below and roughly carve the
wing tip block to fit the wing tip. Glue it to the wing
tip and sand it to the final shape. When you near
the final shape
of the tip block, tape the tip lens to
the wing tip and shape the tip block to match the
lens. To avoid scratching the lens with your
sandpaper, cover it with masking tape.

Note: The trailing edge of the tip block is the
same width as the trailing edge of the wing and
does not taper. This means that the shape
of the
tip block changes from the TE where it is flat to
where it is curved. This gives the wing tip a
concave appearance. Proceed slowly and inspect
your work frequently as you
zero-in on the
final shape.
5. Shape the leading edge of the wing as
shown on the cross section on the wing plan and
blend it to the wing tip lens.
