Hardware for
this assembly
• The use of thread lock MA3200-20
(loctite #243) is recommended on
MA0078 Socket Bolts.
• Do not overtighten MA0065 Socket
Bolts on the Rear Boom Support
Mounts.
IMPORTANT:
•
Aluminum boom support ends have
a dimple on one side. The dimple
indicates a slight angle built in to this
part. On the Boom support assembly
side that attaches to the main frame,
the dimple will be facing “in.”

IMPORTANT:
•
This screw must not be
longer than M3 x 6 mm. If
you use a longer screw the
bearings for the bevel gear
will be damaged.
• Please use some grease or vaseline
or tallow to grease the tail boom from
the inner side and the o-rings of the
torque tube. So the tube will slide
in smooth. If it stops before it is at
the correct position so remove the
torque tube again and apply some
more grease.
• Install orque tube from the tail side
into the boom. It is normally that the
tube goes in strong into the boom.
• The torque tube is at the correct
position inside the boom if at the tail
side the end of the boom ‘cuts’ the
head of the m2 socketbolt in half (top
view at the socket bolt) .
