2.4GHz 4-channel small quadcopter remote control transceiver DIY kit

The small quadcopter remote control kit is an aeromodelling remote control that can control 4 motors at the same time and can realize multiple functions such as one-key takeoff, one-key rollover, and one-key return. This kit is used to design and make your own unmanned remote control aircraft. A 2.4G encrypted signal controls it. The effective distance (60 meters) can be played with multiple sets without interference. The remote control receiver board weighs only 2g and is very light. It can be used to drive four 716 high-speed motors and is suitable for matching 45mm propeller design. Note: This remote control kit can only control motors below 716, such as 716/614 motors, and cannot control motors above 820/8520. Product parameters: Launch board size:52*89MM Receiving board size: 22*46MM Rated voltage: 4.5V for transmitter board; 3.7V for receiver board Remote control distance: within 60 meters Fixed aperture: 2.5MM Complete set weight: about 27 grams Connection instructions: The red and black wires (VCC/GND) of the launch board are connected to the positive and negative poles of the 4.5V power supply; The receiving board plug is plugged into the 3.7V power supply and can be connected to 4 motors. Each group M is connected to the positive pole of the motor, and M- is connected to the negative pole of the motor; The silver wire is the antenna and does not need to be connected. Motor wiring tips: If you find that the motor is turning incorrectly, you can reverse the two wires of the motor and re-wire it to change the direction of the motor. Product description: A. Right-turn flight: The turning force of the two front and rear right-turning motors (produced by the counterclockwise turning motor) is greater than the turning force of the left-turning motor (produced by the clockwise turning motor), which means the fuselage will turn right; The operating principle is that when the speed of the counterclockwise motor increases and the speed of the clockwise motor decreases, the counterclockwise rotor exerts a reaction torque on the fuselage, and the fuselage rotates clockwise under the mechanics of the reaction torque. B. Go straight forward: When the rotational force of the two clockwise motors is consistent, the UAV body will rise. When the power of one group of motors turning counterclockwise is greater than that of the other group, it will push the body towards the weaker side, achieving straight flight. C. Translate to the left: The principle is the same as moving forward. D. Hovering in mid-air: four sets of motors rotate at a constant speed to resist gravity and achieve a hovering effect in mid-air.
