Main Rotor Head Assembly - THUNDER TIGER Raptor 30 V2 Assembly & Maintenance Manual

11 Main Rotor Head Assembly

Assembly Hint: Start from the bottom of the main Rotor Hub and work your way up to the flybar assembly. When
screwing on the flybar paddles to the flybar, stop when you can see the rod in the window of the paddle. Then, lay
the assembly on a flat surface and align the paddles so they are exactly parallel. Insert and tighten the set screws.
Attach the flybar control rod to the flybar control arm and use the Double Link to connect the mixing lever (short
side) to the Main rotor Pitch Housing.
