A. Select two #122-03 Flybar Control Arms, two #0063 M3 x 10 Socket Head Bolts, two #122-18 Threaded s/s

Spacers, two #0572-7 Aluminum Standoffs, and two #0109 M3 x 8 threaded balls. Assemble each flybar

control arm per the drawing. Tighten securely using Blue Loctite.

B. Note: Each Flybar Control Arm #122-03 contains three optional positions. Generally the center hole will be

used, but if increased paddle control is desired, the inside hole may be used or if less control is desired, use

the outer most hole.

C. Study the drawing for the orientation of each flybar control arm assembly. Select the Flybar #0566-1 and

insert it into the flybar support tube assembly bearings on the rotor head block. Visually center the flybar.

Select one #0840-7 4mm Washer and one flybar arm assembly. Slide the washer followed by the arm onto the

flybar, up to the bearing. Repeat this process on the opposite side. Apply Blue Locktite to two #0051 M3 x 3

Socket Set Screws and install one into each control arm. Carefully measure the assembly until the lengths are

equal and no freeplay exits in and out of the head block. Align each flybar control arm until they are level

with each other, then securely tighten each set screw.
