❏
26. Continue forward until you reach the LE with
narrower strips (3/4" to 1"). It will be necessary to
curve the aft edge of the strips to allow them to
conform to the structure.
❏
27. Glue a 3" wide sheet over the center section
between two R-5’s. The R-5B’s serve as a shelf to
support this sheet.
❏
28. Locate the small 1/8" die-cut R-5C sub ribs .
Cut off the small die-cut bump at the narrow end so
the part tapers to a point. Glue it in place at the
outboard end of the oil cooler as shown in the photo.
❏
29. Make a piece of skin to cover the bottom of
the oil cooler from the center of the spar forward to
the LE. Study the photos. Notice how the sheet
blends into the center of the wing. Cut out a small
piece of wing sheeting between R-3 and R-4 just
forward of the main spar. This will allow the oil
cooler sheeting to blend in smoothly.
❏
30. Glue the oil cooler skin in place.
❏
31. Continue sheeting aft in 1-1/4" to 1-1/2"
increments. Allow the flap pushrods (if any) to exit
as shown.
❏
32. Sheet the rest of the wing center section
between the R-5’s. The rectangular hole shown
allows the aileron servo to protrude into the belly-pan.
❏
33. Cut out the vacuum formed oil coolers just
below the faint cut line on the inside. Use coarse
sandpaper to sand the part exactly to the line.
❏
34. Place the oil cooler on the wing. Trace its
location onto the LE of the wing. Cut away balsa
under the oil cooler until it will blend nicely into the
wing. You will need to remove a fair amount
of wood.
❏
35. Glue the oil cooler to the wing. Shape the
surrounding area to blend into the formed oil coolers.
Lightweight filler may be used to fill any gaps.
❏
36. Use a portion of the provided 3/8" x 1/2" x 24"
stick to fair the outboard ends of the oil coolers.
The wing will be completed after the
Fuselage Construction
.
