o 18. Locate the two fuselage stringers. Very gently, so as to
not twist the fuselage, glue the stringer at a 45 degree angle
to the sides of the fuselage by applying a small amount of
glue to the beveled portion of the stringers. Once the glue
has had time to cure, reinforce the stringers by applying glue
to the seam between the stringers and the fuse halves.
o 19. At this point double check to make sure the motor
mount is in the center of the airframe, and then glue it into
position. Carefully remove the bottom pieces of the build jig
by cutting or breaking them.
INSTALL THE SERVOS
AND PUSHRODS
For your convenience, the aileron and elevator pushrods
have been pre-assembled. If you are not using Futaba
S3114 servos, or due to manufacturing tolerances, it may
be necessary to change the pushrod length. This may
be done by holding the heat shrink tubing that connects
the pushrod to the z-bend and gently rotating the z-bend
until the glue holding the z-bend in place has broken
loose. Then adjust the length by pulling or pushing the
z-bend until the appropriate length is achieved, and re-
glue the z-bend to the pushrod using some CA glue.
