1.6 Installing the swashplate
(bag J2-1)
Unscrew the lateral retaining screws in the dome bearing plate and slide the plate up the main
rotor shaft as far as it will go, so that the swashplate guide 4618.113A can be installed using two
M3 x 16 socket-head cap screws, as shown in the illustration.
Locate the linkage ball on the swashplate 1234 which features a projecting pin, and press one
of the pushrods "C" onto it. Grease the guide pin and slip the brass sleeve on it, then fit the
swashplate on the main rotor shaft, engaging the guide pin and sleeve in the swashplate guide;
pushrod "C" must run down through the opening in the dome bearing plate. Now slide
everything (swashplate, dome bearing plate and swashplate guide) down until the dome bearing
plate can be re-installed in its original position. Connect the bottom end of pushrod "C" to the
rear pitch-axis / collective pitch servo.
1.7 Installing the remaining pushrods
Connect the output arms on the left and right roll servos to the appropriate bellcranks using the
two pushrods (A).
Connect the bellcranks to the linkage balls on both sides of the swashplate using the two
pushrods (B).
Connect the front pitch-axis / collective pitch servo to the front linkage ball on the swashplate
using the remaining pushrod (C).
