NOTE

: The longevity of the shafts and gears within the tail rotor gearbox can be greatly enhanced by Amounting@

each with red or green Apermanent type@ Loctite. Each part should be cleaned with alcohol at the contact area.

Follow directions provided by Loctite. Removal will require a modeler's heat gun. We recommend that 3-D

and/or experienced pilots consider this option.

Some assembly positions will require red or green (both are permanent type) Loctite. Please do so, as this is a

critical procedure required for proper tail rotor function.

WARNING: FAILURE TO ACCURATELY FOLLOW THESE INSTRUCTIONS COULD

RESULT IN LOSS OF TAIL ROTOR CONTROL.
