• Wing connection to the fuselage
Prepare two of main wing pins. Lubricate them with an appropriate quantinty of vaseline. Pay attention
to their correct position - UPPER wing pin is WITHOUT thread, LOWER wing pin is WITH thread.
The assistant holds the wing on the wingtip and you hold it by the root (the third person can hold the
wing by the flap).
Pick the wing up and attach it close to the fuselage so that pushrods (aileron and flap) enter the fuselage
through the corresponding holes. But, keep the space between the wing and fuselage to reach enough
access to be able to connect the rest of the equipment protruding from the wing. All persons keep
holding and supporting the wing to avoid its fall. You can support the wing by your knees at the area of
wing root (or the third person can assist with) to connect the rest of the equipment:
- static and dynamic pressure hoses of Pitot tube (just on the left wing)
Note: Pay attention not to interchange the hoses of Pitot tube during assembly.
- quick couplings of fuel hoses
- cable connector of the fuel gauge
- cable connector of the strobes/position lights (if equipped with)
Attach (push) the wing towards the fuselage completely without any gap in between. Insert the main
wing pins into the hole with fittings (wing attachment) inside. Insert the upper pin (without thread) first
and then insert the bottom pin (with thread). This operation requires careful use of the hammer and
auxiliary metal rod (Ø 18mm) to beat the pin into the hole. During this operation, the assistant (holding
the wing by the wing tip) pays attention to keep the correct dihedral angle. If needed, he can slightly lift
the wing to fit the fittings exactly with the hole in correct position and so to enable pins to easily pass
through the fittings. Both pins must be inserted to their fully beaten position. Then the assistant can
leave the wing.
Secure the pin from upper side by the bolt and tighten by torque approx. 25 Nm. Install the M10 locking
nut from the bottom side, so that the wing connection is properly secured.
Cover the holes with any plastic white sticker (to avoid water intrusion).
• Flap pushrod connection inside the cockpit
Take the seats out of the cockpit to reach an access to the flap control lever situated in the central
tunnel. Connect the pushrod with the flap lever by the pin Ø 5mm and spacer + split pin (all parts
delivered with the pushrod). You can insert the pin Ø 5mm via from the bottom side (better accessibility
for the spacer and split pin installation). Install seats back.
• Aileron pushrod connection inside the cockpit
Screw the pushrod to the control stick until the connection is fully tightened. Then loosen it again by the
number of turns indicated on the pushrod. This ensures correct neutral position of the aileron. Secure
the connection by the pin Ø 5mm and spacer + split pin (all parts delivered with the pushrod).
