The SunFounder 2.4GHz 6CH RF Receiver-Transmitter Radio Transmitter is a left-throttle one, powered by six 1.5V batteries. As a 6-Channel 2.4GHz radio frequency (RF) transmitter, it only supports PPM signal output. The first, second and fourth channels support the trim function. Overall, it boasts the basic and popular functions for radio transmitters on the market but with better performance, including low-battery alarm, strong anti-interference, fast response, and stable remote control in a certain distance. Thus it's widely used for control system of aircraft models that require remote control in a long distance and other applications.


1. Radio Transmitter (6CH PPM)

1) Operating frequency: 2.400-2.4835MHz
2) Modulation system: FSK
3) TX transmit power: 13dBm
4) TX current: 60mA
5) Modulation signal: 6CH standard PPM signal
6) Working voltage: 9 V (6*1.5V)
7) Remote control distance: horizontally about 500m in an open field

2. Receiver (6CH PPM)

1) Operating frequency: 2.400-2.4835GHZ
2) Working voltage: DC 4-8V
3) Operating current: 20mA
4) Sensitivity of receiving: -100dBm
5) Demodulation output signal: 2-6CH standard model PPM signal
6) Support receiving sensitivity adjustment and light indication for pairing
7) Distance for receiving: horizontally about 500m in an open field


1. Take the following steps to pair: press and hold the pairing button of the receiver, and then power the receiver. Release the button, and the LED will flash fast on it. Then switch on the radio transmitter, and the LED on the transmitter will keep flashing, indicating it is pairing with the receiver. After a while the two LEDs will stay steady on, meaning the pairing is done successfully. Now you can pull the stick on the transmitter normally. It needs no switching on again, which is easy and convenient.
2. You need no more pairing later once it's done well for the receiver this time.

Mix button: Press it switch on/off. When it's on, if you pull the stick on the right to left, the aircraft will fly to the left and backwards at the same time; if you pull it to the right, the drone will fly ahead and to the right; if you pull it forward, the model will fly to the right side; pull it backward, and the quadcopter will fly to the left side.
Channel #1 - Roll: Control the direction of left and right. Pull the sticker to the left, and the drone will fly to the left, and vice versa.
Channel #2 - Pitch: Control the direction of forward and backward. Pull the sticker forward, the plane will fly forward, and vice versa.
Channel #3 - Throttle: Control the rotational speed of the four motors.
Channel #4 - Yaw: Control the orientation of the whole plane.
Dual-rate switch: After this switch is on, the threshold of control for each channel (except throttle) will be switched to the larger when you pull the stick to the maximum.
