Before rigging, insert draining plugs into root ribs - grease with Vaseline if necessary – and remove
valve opener.
2.
Before extending landing gear check for adequate ground clearance.
3.
Clean and grease all pins and matching bushes including main pins and automatic control system

lever(s) rearward).
Warning: When ailerons are deflected upward during rigging, then the automatic aileron
connector lever strikes against the fuselage deflector and thus prevents rigging.
Do not use brute force !
Warning: When cockpit water ballast levers are not in "closed" position, wings can not be
rigged.

Rig wings in 15 m (49 ft) version and always without winglets;
for winglet installation see page 4-3.
6.
Insert right spar end into fuselage, aileron must be about neutral and watch for angle of dihedral.
7.
Insert left spar end into fuselage, aileron must be about neutral and watch for angle of dihedral.
8.
Insert main pins completely when
bushings
are lined up correctly.
9.
Secure main pins by placing handles behind spring loaded pegs.
