The collective control is the lever that is on the floor of the cabin to the left of the pilot, it is used to move the blades of the main rotor and generate torque so that the helicopter rises or descends. This one works with Throttle

The accelerator is the turned control that is at the end of the collective control, it works with slider 1. If you look at the collective control there is a mark that indicates how far you should accelerate the engine (it must be in first person)

The cyclic is the "lever" located directly in front of the pilot's seat. Control the blades to make the helicopter move forward, backward and sideways. works with roll & pitch.

The rudder is controlled with the two pedals on the ground, to move the nose of the helicopter to the right or left, it works with Yaw.
