Hardware for this
assembly
Assembly Tips
• The use of “243 blue” thread lock
such as MA3200-20 (loctite blue #243)
is recommended on MA0078 Socket
Bolts.
• Do not overtighten MA0065 Socket
Bolts on the Rear Boom Support
Mounts.
•
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.”
Apply a small amount of
medium thread lock when
threading into metal parts
Assembly Tips
• Pour some light oil such as Tri-Flow
into tail boom to ease installation of
torque tube assembly.
• Install the torque tube with the open
ends of the bearing cups towards the
back of the tail boom assembly. This
will ensure the bearing stays seated
in the bearing cup.
• Install MA128-144 T/R Control Rod
Guides with the dimples towards
front of tail assembly. Use a small
amount of cyanoacrylate
glue to ensure each
guide stays in
position.
