A RC transmitter (aka radio controller, or TX) is a tool that lets in the pilots to manipulate the aircraft wirelessly. The signal/instructions are then received by a radio receiver (RX) which is connected to a flight controller. If you're new and inquisitive about flying drones , you have to test out the beginner guide to mini quad racing. Channels The range of channels determines how many person motions on the aircraft can be managed. For example, throttle, yaw (rotating proper and left), pitch (lean ahead and backward), and roll (roll left and proper), everyone takes up 1 channel. And so as you could see, 4 channels is the bare minimum to control a quadcopter (pitch, roll, throttle, yaw). But for interest grade quadcopters, you genuinely want greater channels. Additional channels on a transmitter are frequently known as AUX channels (Auxiliary), in the shape of switches and pots (potentiometer or knob). You can use them to alternate flight modes or cause certain f...
