rotor support, you will need to file back the edge of the GRP moulding to the point where the tail
rotor can be operated over its full range of movement without the pushrod fouling or rubbing at
any point.
For the following stages we recommend that you temporarily remove all or part of the tail rotor
control system to provide better access to the inside of the tail boom.
1.7 Stabiliser panels
Sand the two 4 mm Ø CFRP rods with fine abrasive paper and remove rough edges from the
ends. Round off the ends slightly. Drill 4.2 mm Ø holes for the carbon fibre horizontal stabiliser
joiner rods in the tail end of the fuselage.
Here again the fuselage moulding features markings which can be used as a starting point, but
remember to correct the position of the holes if necessary: the carbon fibre rods must run
through the tail boom exactly horizontal and parallel to each other when viewed from the tail,
and must be at right-angles to the boom centreline when viewed from above.
With the carbon fibre rods correctly positioned, and projecting an equal distance out of the tail
boom on each side, glue them to the fuselage by applying epoxy adhesive on the inside of the
tail boom. This is best done in two stages, right then left, leaving the fuselage resting on the
appropriate side until the epoxy has cured.
