❏
Install the two control sticks on P/N 701 as shown in Figure 32. See Drawing No. 126.
❏
Install P/N 718 on the two control sticks. See Drawing No. 126 and 718. Note on
Drawing No. 718 that the ends of the control stick connecting rod are not symmetrical.
One side is shown as 3mm from the outside of the tube. This is the forward end.
Landing Gear Retraction Gearbox Assembly
In the following sequence, you will assembly the landing gear retraction gearbox. The alignment
of the gears is important and you should make every effort to see to it that the gears run smoothly.
One of the difficulties that you will encounter is holding a gear in position on a shaft while you
drill the hole for the roll pin. One technique that you might want to consider is to use Loctite to
bond the gear to the shaft after it is correctly aligned. In a few hours, the Loctite will harden and
the hole can be drilled. To use Loctite, the mating metal surfaces should be clean and free from
any oil. While it is unlikely that you would ever need to, the principal disadvantage of this
method is that Loctite is so strong that it will be extremely difficult to disassemble the gearbox.
❏
If desired, P/N 520-2 gearbox may be primed with zinc chromate primer. Mask off the
bearings to prevent paint-induced friction. The bearings in the P/N 520-2 gearbox are
intentionally installed with a fit that is not tight so that the shafts will turn with a
minimum amount of friction.
❏
For easier assembly, install P/N 623 bushing in each end of each MS20271-B14 universal
joint with Loctite. See Drawing No. 102. Allow it to harden for several hours.
