Saw out the panel, referring to the dimensions in the photo above, then clean up the
edges and cut it exactly in half lengthways to form two doors. The motor unit is in-
stalled in the fuselage using a pair of aluminium brackets which are screwed to two
half-formers; this procedure is also described in the motor unit instructions.
The first step is to attach the two aluminium brackets and the half-formers to the mo-
tor unit inside the fuselage. Position the motor assembly accurately, and tack the two
half-formers to the fuselage. The additional support for the motor unit is screwed to
the rear retract unit former. When the motor is retracted, the two doors are closed
again by means of two torsion springs. End-stops for the doors have to be glued to
the inside of the fuselage at both ends of the motor opening, as already described for
the retractable wheel.
The wings
Work on the wing panels is limited to installing the servos and the control surface
horns. Heat-shrink sleeves should be shrunk round the servos before they are glued
in the wings. Thoroughly roughen (sand) the gluing surface of the servos and the in-
side of the wing panels to ensure that the glue adheres well. The position of the ai-
leron horns is shown in the photo: they should line up with the pushrod fairings. Mark
the position of the horn slots on the ailerons in line with the centre of the pushrod fair-
ings, and cut the slots out accurately. Note that the horn linkage point should line up
exactly with the aileron hinge pivot axis.
