Build the stab build the tail surfaces – Great Planes Giles G-202 46 Kit - GPMA0238 User Manual
Page 7

You may remove the stabilizer and elevator drawing from
the wing plan by cutting along the dashed line. Don’t forget
to cover the plan with Great Planes Plan Protector so the
glue won’t stick to the plan.
While the placement of the outer framing of any stick-built
part is important, the exact placement of the internal ribs
is not so critical. It is more important to have the ribs fit
properly between the framework and have strong, secure
glue joints than to have them placed in an exact location.
If you need to slide an internal rib up or down as much as
1/8" within the Giles’ tail framework to gain a snug fit and
a strong glue joint, feel free to do so.
Note: Be sure to save all of the leftover pieces from
building the stabilizer. These pieces will be utilized in
constructing the fin. Construction photos are shown off
the plans for clarity.

1. Pin the die-cut 3/16" balsa stab LE brace in position
over the plan. Fit and glue the die-cut 3/16" balsa stab center.
❏
2. Position the 3/16" x 3/16" x 10" basswood stab spar
over the plans. Sand the ends to the taper shown. Glue the
stab spar to the rear of the stab center.
❏
3. Using two 3/16" x 1/2" x 24" balsa sticks, fit and glue
the stab leading edges and stab trailing edge. From a
3/16" x 1/4" x 24" balsa stick, fit and glue the stab ribs. (Be
sure to save the leftover pieces for building the fin.) Note:
Hold a non-slip straightedge behind the stab trailing edge
while fitting and gluing the stab ribs to help ensure a
straight trailing edge.
Hint: Single-edge razor blades work very well for making
clean vertical cuts in sticks such as those used for the tail
framework on this model.
❏
4. Unpin the stab from the plans. Inspect all glue joints
and re-glue with CA as necessary. Use a bar sander and
220-grit sandpaper to sand the entire top and bottom
surface of the stab framework until it is flat and even. Be
careful while sanding so that you do not over-thin any one
particular area of the stab or gouge the stab ribs by
snagging the sandpaper on them.
❏ ❏
5. Position the stab on a 1/16" x 4" x 30" balsa stab
sheeting, aligning the sheeting with the TE and one end of
the stab. Using medium CA, glue the stab framework to the
stab sheeting.
Note: Give the CA ample time to cure before lifting the
assembly off the building board. It is essential to get a very
secure and uniform bond between the stab sheets and the
stab core, especially in the center.
❏ ❏
6. Place the sheeted side of the stab on the building
board and trim the sheeting around the outer edges of the
framework. Save the remaining pieces.
Note: Refrain from using excessive accelerator. Even
hours after it’s sprayed on, residual accelerator can
prematurely and unexpectedly cure the CA you use later
on nearby glue joints. Unless you must handle or remove
the part from the building board right away, we
recommend using no accelerator at all.
