FLIGHT MANUAL
4.2.1 Rigging and de-rigging
Rigging
The Arcus M can be rigged by two people if a wing stand or trestle is used under
one wing tip.
Prior to rigging, all pins and their corresponding bearings on fuselage, wing panels
and tailplane should be cleaned and greased.
Inboard wing panels
Unlock the airbrake lever and set water ballast control lever to “CLOSED” -
flap position "L".
Insert the left wing panel first. It is important that the helper on the wing tip should
concentrate on lifting the trailing edge of the wing panel more than the leading
edge, so that the rear wing attachment pin does not jam into the fuselage bearing.
Check that the spar stub tip is located correctly in the cut-out on the far side of the
fuselage and that the fuel- and vent pipes are located correctly in the
corresponding cut-out in the fuselage (if necessary, tilt the fuselage or move the
wing gently up and down to help it home).
Check that the angular levers on the wing root rib are properly inserted into their
corresponding funnels on the fuselage.
Push the main wing pin in approx. 3 cm (1.2 in.) so that the wing panel is
prevented from sliding out by the cut-out in the vertical rim of the GFRP-panel
covering the front wing locating tube.
The wing tip can now be placed on a wing stand.
Next insert the right wing panel – the procedure is the same as for the left wing. As
soon as the pin on the right wing spar stub has engaged in its corresponding
bearing on the opposing wing panel (recognized by a sudden extension of the
unlocked airbrakes), the right wing panel can be pushed fully home under some
pressure.
If it is difficult / impossible to push fully home, remove the main wing pin and draw
the panels together with the aid of the rigging lever (use flat side only).
Finally push the main wing pin fully home and secure its handle (depress locking
pin and let it engage in the metal fitting on the fuselage inner skin).
