There are several types of remote controls and these are also categorized by the zone you are located in. The Mode 2 is used in North America, this has the throttle and yaw stick on the left side and the roll/pitch stick on the right side. While the left side stick has spring loading on the yaw only, the right side stick has spring loading on both axis. On the left side you can see an image of the FrSky Taranis transmitter which is one item you should be investing in right from the beginning.
Let’s clarify some terms about transmitters before we go further. I know this is common knowledge to most of the people already flying, but you can link or send this article to all those who are just starting up and need clarification.
A remote control transmitter is qualified by one main thing these days: how many channels are available on it. The Taranis is a 16 channel radio, it will allow you to send 16 different signal streams to your flying bird if it is properly set up. No worries, you will most likely never be using more than 8.
So what are the controls on your remote? For now forget all about the switches on the top and let’s concentrate on the two main sticks, this is what you will fly your bird with.
On a mode 2 transmitter you have the following controls:
|Throttle, by default this stick is in the lower position and you need to push it upwards to increase the throttle.|
|Yaw/Rudder this controls the nose of your craft. If you are standing behind the bird and you pull this stick to the left, the nose will (should) turn to the left, or if you pull it to the right, the nose should turn to the right.|
|Roll/Aileron, spring loaded, this stick goes back to the middle when released. This controls the drones left right movement, meaning horizontal shift toward left or right when looking from behind the bird.|
|Pitch/Elevator, spring loaded, this stick goes back to the middle when released. This stick controls the forward/back movement, when you push this ahead the drone moves forward. Pull it back to make it come backward.|
So each stick corresponds to one channel on the radio. To fly a drone or multirotor, you will need a minimum of 4 channels as described above. Every additional channel you can spare can be used for different other types of auxiliary controls.
