Step 5. Turn the wing into a horizontal position and push it gently towards the fuselage.
Step 6. Lifting the tip, slowly insert the wing roots into position in their channels, leading edge first. It
may be necessary to gently rock and twist the wing to engage the spar hooks on to their pins.
Step 7. Ensure that front and rear wing spars are properly engaged in their channels. Then insert the
lower end of the wing struts into the open box-section end at the top of the shock absorbers.
Step 8. Attach front wing bolt and safety pin, using the tool provided.
Step 9. Attach rear wing bolt and safety pin.
Step10. Attach the strut bolt through the box-section end and lower steel block of the wing struts ends.
Install the safety pin.
Step11. Check that all three bolts have their safety pins installed.
Step12. As a final check, lift the wing at the wing tip to ensure proper attachment of the wing strut block
to the box-section end.
Step 13. Connect the pitot tube to its fitting situated to the left of the pilot’s headrest. Pull out the pitot
tube forwards to its full extent.
Step 14. Repeat steps 1 through 12 for the other wing. Now you may remove the control lock.
Step 15. Attach right and left aileron push rods to the central bellcrank connection. Carefully ensure that
the slide mechanisms of the special link connectors are properly engaged (closed and locked).
Step 16. On the flap drive tube, take the split sleeve fitted around the sprung taper pins (and through
which they protrude), spread it a little, then rotate it over the pins. Using this sleeve as an aid,
squeeze it, thus compressing the pins. Then move the sleeve so that the drive fitting moves
freely on its tube.
Step 17. Align the flap root tube and its drive fitting on the fuselage. Slide the flap drive fitting over the
junction so that its cutaways engage snugly in the roots of the flap frame tubes and the sprung
pins are fully out. Rotate the split sleeve so that its holes align with the tips of the pins again,
permitting the pins to spring out fully. Left and right landing flap must be securely locked and
it may be necessary to wiggle the fitting a little to ensure proper engagement, particularly when
the aircraft is new.
Step 18. Position and fasten the wing centre section (cockpit roof).

Folding the wings to hangar the aircraft:
Step 1. Apply the brake. Fit the dolly wheel to the stern post.
Step 2. Push in the pitot tube on the left wing.
Step 3. Remove wing centre section.
Step 4. Disconnect the pitot tube from its fitting above the pilot’s seat back.
Step 5. Place a triangular wooden support bracket (supplied) on to the lower part of the tailplane strut
at each side, with the aluminium strip uppermost.
