Flybar Control Arm
Begin by attaching six No.17 Link Balls to the No.9 Flybar Control Arms and No.12 Mixing levers using No.1 Screws. Slide No.4
BRG, No.11 Fly Arm Bushing and No.9 Flybar Control Arm onto the No.12 Flybar Rod. From the other end of the Flybar Rod,
slide on the No.10 Seesaw Hub and the other No.4, 9, 11. Make sure the Flybar has equal protruding from each side of the Seesaw
Hub, then install and tighten the No.6 HME4-5B set screws. Add the paddles. Make sure the two paddles and the two flybar control
arms are all parallel. Lock the paddles with No.5 set screws.
Assemble and install the No.12 Mixing Levers and No.7 Bearings according to the drawing using No.8 Collar so it will stay with
the inside surface of the ball bearing. Be careful do not let the Loctite seep into the bearings.
Note: Before installing the Mixing Lever (No.12), please add a small drop of Loctite along the entire length of the M3x18 socket
screw (No.2) and on the outside of the collar d3xD4x13 (No.8). There are two choices of the hole positions on the aluminum
seesaw for attaching the mixing lever arm. Please use the outside hole position, this gives higher Bell-Hiller mixing ratio and
more stability. For very aggressive 3D flying, attach the Bell-Hiller mixing arms to the inner hole on fly seesaw, but the optional
metal flybar control arms (No.PV0294) must be used, otherwise the mixing arm can touch the plastic flybar control arm.
