In order to easily place the belt over the
gear it is recommended that you unscrew
the bolt and screws on the boom holder. It
is then possible to push the boom further
into frame.
In order to align the belt correctly - using a
screwdriver rotate the belt 90° anti clock-
wise.
Then slip it over the gear.

Pull the boom back through and into place.
This should result in optimum belt tension.
To test the tension apply pressure onto one
side of the belt. It should not be so tight
as to not move and should not be so loose
as to touch itself. If adjustment is required
move the boom forward or back appropri-
ately. Tighten the boom holder screws once
the boom is correctly positioned.

Insert rear aluminium rear spacer. Assemble
the boom supports and screw into place on
the spacer - on both sides. Use thread lock.
Screw the other end of the boom supports
into place on the horizontal tail fin bracket.
Cut out horizontal fin decal and stick to fin.
Affix horizontal tail fin to the bracket - use
a drop of thin CA to secure the ends of the
boom supports.
