To assembly the two wing halves to the fuselage, an aluminum tube with an external diameter of 3/4”
(19.05mm) x 1mm thick x 648mm long is used. The wing/fuselage assembly is factory preset and uses 2 1/4" x
3/4" allen screws and 2 washers (supplied with the kit), 1 screw with washer on each side. Insert the tube into
the fuselage until it is centered. The wing halves have 3 holes at the root, the front one to allow the passage of
the ailerons, flaps and lights servo extensions into the fuselage, the central one where the tube must be inserted
and the rear one, to allow the passage of the retractable extensions and servos. At the rear is a rigid wooden
dowel to align the wing halves at their correct angle of incidence (0 degrees). The drawing below shows the
position of the 3 holes and pin. Insert the wing halves.
Check that the wing roots are perfectly aligned with the shape of the wing on the fuselage. Insert screws with
washers through the retracts compartment at the bottom of the wing halves into the holes identified below by
the letters X and tighten them until they are tight. We recommend the use of a medium grade thread locker
(removable).
IMPORTANT: THE WING FIXING SCREWS MUST BE INSERTED FROM THE OUTSIDE OF THE FUSELAGE IN AND
NEVER FROM THE INSIDE OUT.
Elevators: 2 simple horns with height between 15mm to 20mm required. The servo arm (length between 20mm
to 25mm from center to end) should be positioned with the control arm centered on the bottom of the
stabilizer. The horn hard points are centered with the straight line formed by the rib where the servo arm is
exposed. Mini servos installed on laser cut plywood structural ribs with servo box covers.
