Installing the boom into the frames: Use the plastic boom holders and
four 3 x 35mm cap head bolts with four 3mm Locknuts. With the belt
straight in the boom, point the tail rotor assembly towards the sky. Slide
the belt over front pulley and make the belt snug. Rotate the boom to the
right 90 degrees. After the boom has been rotated into the proper
position, test the tension of the belt by depressing the belt approximately
¼ the width of the boom. Tighten the bolts making sure everything is
90 degrees and square. Simpily slide the horizontal fin mount over the
boom for later use.

Attaching the boom supports: The first step in mounting the
dual booms supports to your machine is to attach them and
make a dry fit. The ends that bolt to the lower main frames are
fastened with 3 X 10mm cap head bolts and 3mm lock-nuts. The
two ends that attach to the horizontal fin mount use a
3mm X 18mm cap head bolt and a 3mm lock-nut. After the
boom supports are dry-fitted, drill out aluminum support end holes
by first using a 1mm drill, then a 2mm drill and finally a 3mm
drill. Complete the installation by applying a thin layer of CA
glue on the outside of the carbon rod, slipping the alum. ends
over rod and finally installing the 2.6mm X 10mm cap
head bolts.
