Recommended building methods and glues:
Much of the construction of this model is done by laying
the parts on a flat table. It is strongly recommended that
you put wax paper down on the surface first so any excess
glue doesn’t soak through the foam and glue the parts to
the table. For all assembly, use thin “foam safe” CA glue.
Gap filling or “medium” glue just adds weight. Always use
accelerant or “kicker” to get the glue to set. If possible,
apply the glue to one part and the kicker to the other part
and then press them together and hold until cured. Wipe
off any excess glue with tissues before it cures.
Wing Preparation:
Apply hinge tape to the top of the aileron hinge lines.
Carefully fold the aileron back onto the wing. Using
medium sandpaper and very light pressure sand the
inside of the vee so that the aileron will move freely.
On the “vee” side of the hinge, apply a 1” long piece of
hinge tape in the area of the bottom wing where the
control horn slots are (near the center of the wing).
Cut one flat carbon piece 32 1/2” long. Lightly sand the
“glue side” of the carbon strip to improve glue adhesion.
Lay the wing on a flat table (with wax paper underneath).
Carefully glue the flat carbon to the leading edge of the
wing. The easiest way is to apply glue to the flat carbon,
spray kicker on the wing leading edge and then bring the
two together (on a flat surface). Do one wing panel first,
then once it is cured, wrap the carbon past the wing
centerline and do the other half of the wing.
