approximately 3/8" [10mm] of the dowels protrude from the
leading edge.
4. After the epoxy has hardened, place the wing on the
fuselage. Stick a T-pin into the center of the rear of the
bottom of the fuselage. Tie a loop in one end of a 40" [1m]
piece of non-elastic string such as monofilament or Kevlar
line (K+SR4575). Slip the loop in the string over the T-pin.
5. Fold a piece of masking tape over the string near the
other end and draw a sharp arrow on it. Slide the tape along
the string and align the arrow with one end of the wing as
shown in the photo. Swing the string over to the same
position on the other end of the wing. Pivot the wing and
slide the tape along the string until the arrow aligns with
both ends of the wing. Now the wing will be centered.
6. Bevel the front and both ends of one side of the bolt
plate (BP) as shown in the photo. Glue the bolt plate to the
bottom of the wing centered on the fuselage.
7. Recheck the wing alignment. Using the holes in the bolt
plate as a guide, drill #7 (.201" [5mm]) (or 13/64") holes
through the wing and wing bolt plate in the fuselage. Be certain
to hold the drill perpendicular to the bottom of the wing.
8. Remove the wing from the fuselage. Thread the holes
in the wing bolt plate with a 1/4-20 tap. Add a few drops of
thin CA to the threads in the holes and allow to fully harden.
Run the tap back through, then repeat the procedure one
more time.
9. Enlarge the bolt holes in the wing with a 17/64"
[6.4mm] or 1/4" [6.8mm] drill. Mount the wing to the fuselage
with two 1/4-20 nylon bolts to see how it all fits (the bolts
may be cut down to 1-1/4" [30mm]).
Install the Guide Tubes, Fuel Tank,
1. Cut both 3/16" [4.8mm] gray plastic pushrod guide
tubes to a length of 18-1/2" [470mm]. Use coarse
sandpaper to sand the guide tubes so glue will adhere.
Insert the tubes through the holes in the fuselage formers as
shown on the plan. Note that the tubes cross between
formers F4 and F5.
