How does a tandem helicopter steer?

There is a part on a helicopter that is called a swashplate, it converts non rotating controls into rotational movements via an inner ring riding on a bearing attached to an outer ring that is able to pivot on the shaft. On a tandem helicopter it uses both of them in unison most of the time. A helicopter maneuvers by adjusting the pitch of the blades to be more biased to one side, basically pushing air at an angle, causing it to go the opposing direction. So when a tandem rotor helicopter wants to fly forward it pitches both (or even one depending on what you want to do with it exactly) to fly forward. This all applies to the cyclic (steering). For yaw (turning) they either tilt the back only (to pivot around the front rotors), the front only (to pivot around the front rotors) or both (to pivot around the center). with the joy stick!!!!!!!!

A helicopter with twin main rotors steers by flying the rotors just as a single rotor helicopter would do to make a turn. A single rotor helo uses the main rotor to tilt and bank. For a twin rotor helo, the two rotors do the same but can pivot the helo about its axis. The controls are a bit more complex than for a single rotor.
