Assemble the tail rotor input
shaft by sliding two Ball Bearings
on to the shaft followed by the
large Bevel Gear (B). Align the holes
on the gear with the hole in the
shaft and press in one M2x12
pin and secure with one
M3x4 Set Screw (Tip 1)
using threadlock.
Notice that the tail rotor output drive
shaft has 2 holes, one through the
shaft and one drilled partially into the
shaft. Slide the small bevel gear (A)
with the teeth facing the shaft from
the end with the through hole and
position the gear aligning the holes.
Press the M2x12 steel pin through
and secure with one M3x4 Set
Screw (Tip 1) inserted from the end
of the shaft using threadlock. Slide
the Spacer Tube onto the shaft and
position against the gear.
