About the Radio Transmitter
Since a radio transmitter will be used in software debugging, let’s first learn something about it now.
For more details, please refer to the transmitter’s user manual.
Talking of radio transmitter control, here a term is involved: "
channel
", meaning how many
types of movement the copter can make by the radio transmitter control. For example, up
and down can be counted one channel. If the radio transmitter control can only control
the copter to fly up and down, it's called one channel.
For a quadcopter, at least four channels are needed, namely, up-down, right-left, forward-
backward, and clockwise-counterclockwise rotation. The corresponding channels are
throttle (up-down), roll (right-left), pitch (front-back) and yaw (clockwise-counterclockwise
rotation). If you want more functions, more channels are required.
