Install BK0364 and BK0362 onto BK0365 Tail Gear Drive Shaft. Then insert the
Qty.
two Pins and secure them with two M3x4 Set Screws. Add a tiny drop of Loctite
2
on the set screw thread before inserting them. Always use a very small amount
2
of Loctite liquid on the thread, otherwise it may be nearly impossible to remove
2
the set screws in the future for servicing. After installing the two M3x4 set screws
1
(No. 1), try to push on the 2x12 pins with a small Allen wrench to make sure the
1
set screws have locked the pins in place securely. Install the four ball bearings
1
and the hex shaped Frame Spacers according to the drawing. Before closing
1
the two halves of the Tail Boom Brackets, please check the gear mesh between
1
gears No. 4 and No. 5. If there exists too much freeplay, add some 5 mm i.d.
1
washers on top of gear No. 4. (The 5 mm i.d. washers are provided in BAG G).
