Install the battery pack tray. Place one tabbed end in the notch
of 4B and then rotate the other end down so the tab fits in the
the notch in the bottom of the forward bulkhead.
Install 3/16" square balsa stringers in the slots of the formers. The
outer edges of top formers 3T,4T, 4C, 5T, and 6T are glued to the
stringers that run parallel to the top of the internal liteply box.
Install parts 4S and 7S on each side of the fuselage in the
locations shown. The bottom edge of each part is flush with the
top of the notches in the wing saddle area next to side formers 4

Assemble the two sets of wing saddle parts WS1 through WS3.
The wing saddles are then glued to the fuselage internal box and
the bottom of the side formers. The tabs on the wing saddles fit in
the notches of the liteply box sides. The bottom of formers 5 and 6
along with pieces 4S and 7S match the dihedral angle.
Assemble the motor mount. The mount is set up so the length can
be adjusted for the motor being used. The inner box can slide fore
and aft in the outer box. DO NOT GLUE the inner box in the outer
box until it is time to install the motor. Please note that the inner
box sets the right thrust. Make sure the top and bottom pieces
have the same orientation relative to the slanted faces.
Glue the motor mount outer box to the forward fuselage bu khead.
The tabs of the motor mount box fit in the corresponding slots in
the nose former.
