Push the battery bay and receiver cookies out of the center of the wing
panels. Cut 1/8'' wafer off of the bottom of the receiver cookie using the X-acto Extra
Fine Saw Blade to make a floor for the receiver bay. Cut a 1/4” wafer off the bottom of
the battery cookie to make a floor for the battery bay. Make sure that the floors match the
contour of the wing surfaces.

Servo control arm
Fit to the wing contour
The control rods may not fit in the servo control arm. The end of the control rod can be
filed to fit in the servo control arm or the top hole in the servo control arms can be reamed
by spinning an X-acto #11 blade in the hole or drilling with a #48 drill (.076”).
The wing thickness will accommodate standard servos. Servo control arms should be
straight up facing outboard—toward wing tips. Some standard servos are bigger than
others. It may be necessary to cut or router the servo holes to a tight squeaky fit so that
no glue is necessary. Locate the servo-cut out in the wing panel. Push the cookie cut-out
out of the wing. Slice a 1/4'' wafer off the bottom of the cookie. The X-acto Extra Fine
Saw Blade does an excellent job of slicing EPP wafers. Spray a puddle of 3M Super 77
adhesive on a piece of wax paper or aluminum foil. Touch the edges of the parts to be
glued in the puddle. Glue the wafer back in the bottom of the servo bay as a servo bay
floor. Push the servo into the bay and cut the top of the cookie to fit as a servo bay lid.
Make sure the lid is flush with the top of the wing.
