1.10.1 At the fuselage
a) With the aircraft fully rigged, move the wings fore and aft to determine at
which lift pin the most play exists.
b) Derig the glider.
c) Screw out the lift pin and insert a distance washer (inside diameter
16.5 mm (.65 in.)) and screw in the pin again. Tighten the lift pin.
d) Rig again and check the free play.

a) Check see above.
b) Roughen the area around the lift pin and attach a distance washer inside
diameter 10.5 mm (.41 in.) 0.25 mm (0.01 in.) thick with a suitable metal
adhesive (e.g. Stabilit Express). Note the total thickness of the washers at the
root rib with a waterproof marker pen.
c) Rig the wing tips again and check the free play.
1.10.3 Tolerances
Free play should be adjusted if you hear a rattling sound when moving the wings
backwards and forwards. The max. amount of free play can also be determined
as follows: Measure the free play at each lift pin with a feeler gauge. Sum up the
free play.
At fuselage: The free play of all 4 pins together should not exceed 0.5 mm (0.02
in.).
At the wing tip joint: The free play of the 2 pins together should not exceed
0.5 mm (0.02 in.).
