Grease to be used inside the tail gearbox should be a teflon, light
lithium or silicon type of grease commonly found in a hobbyshop
for R/C cars. Do not use any grease on any other gears.
Step 67 Tail Gearbox Assembly
Apply a small amount of L262 Red threadlock
to the end of the tail output shaft and slide one
M5x11 ball bearing in place flush with the gear.
Slide the tail boom into the left half, ensuring
that the hole in the tailboom half engages the
boss in the gearbox. Press the left tail gear box
half to close the gearbox and insert one M3x10,
M3x15 and M3x20 socket cap screws from the
left half. Secure using three M3 locknuts.

Step 68 Tail Pitch Plate
Apply a small amount of slow cyanoacrylate glue to
the lip on the brass tube and insert into the flat side
of the pitch plate (the molded stand off is flush to the
bearing) and press firmly in place. Apply a small drop
of L262 Red threadlock at the joint of the pitch plate
and the tube and slide one M6x10 ball bearing, fol-
lowed by the pitch plate housing. Slide the second
M6x10 bearing and apply the L262 Red threadlock
with a needle to the joint between the bearing and the
brass tube. Allow the threadlock to cure. Slide the
M6x9x0.35 flat washer and the lock ring to secure the
assembly together. Using slow cyanoacrylate or JB
Weld bond the lock ring to the brass tube.
