Q

Explain control flight function.

A

Collective stick changes the angle of all four blades at the same time increasing or decreasing lift

Cyclic stick changes the pitch of the swash plate which changes the angle of one blade at a time allowing the aircraft to roll left, right, pitch up or pitch down

Rudder pedals changes the angle of the tail paddles which controls heading

Q

Explain cycle stick function.

A

changes the angle of all four blades at the same time increasing or decreasing lift. It is attached to the flight control rods inside the broom closet then linked to the torque shafts that lead into the boost servo and the mixer. This moves the primary servos forward or aft which moves the pitch control rods up or down which then changes the angle of the blades allowing for increased or decreased lift
