48. Test the fit of the die-cut 1 /8" plywood R-
1 B's (1 B) against the R-1 A's. Trim the Ft-1 B's
if necessary for a good fit. The dowel may also
need to be flattened slightly with a sanding block
to allow the R-1 B's a good fit.
49. Glue in the R-1 B's with 15-minute epoxy.
50. For rubber band on wings, glue the die-cut
1/8" plywood R-1 B's to the R-1 A's, forward center
brace (F), and dihedral brace with epoxy.

52. Snap the die-cut 1/8" plywood aileron
servo tray and servo tray support in place as
in the photo. Use medium CA to glue in the
servo tray support while using the servo tray to
hold it in position. Do not glue the servo tray in
at this time.
53. Sand the root ends of the tapered and
grooved balsa trailing edge center pieces so
they will meet properly when they are held
together against the TE. Mark the parts so you
can identify the bottom of the left and right parts.
54. Hold the trailing edge center pieces over
the right wing panel plan. Mark where the
torque rods will exit the bottom of the trailing
edge. The root cross-section gives a view of the
cut-out. Cut a notch in the trailing edge center
pieces to allow the torque rod to exit.
55. Hold the trailing edge center pieces up
to the wing. Transfer the notch locations onto
