Agusta A119 Koala - Graupner

Agusta A119 Koala
Drill two 2 mm Ø holes in each of the carbon fibre skid tubes, taking care to drill at exactly the
same angle: the rear ones should be 22 mm from the end, and the front ones spaced 135 mm
from them. Caution: do not drill right through the tubes: just drill into them!
Fit the two skid bars into the holes "dry" (no
glue), and tape the skid tubes down on a flat
surface as shown: the tubes should be 108
mm apart, perfectly "square" and parallel to
each other.
Remove the skid bars from the skid tubes
without disturbing the tubes, and slide lengths
of 3 / 2 mm Ø plastic tube onto them; the ends
of the steel bars should project by about 4
mm; roughen the exposed ends using
abrasive paper.
Now fit the skid bars into the (still fixed) skid
tubes, set them parallel to each other and tilted
to the rear slightly, then glue them securely to
the skid tubes using cyano.
Glue a 20 mm long beech dowel in the front
end of each carbon fibre tube, leaving half their
length projecting.
