Specification:- Launch Plate: 2.2V -4.5V,(2-3 batteries, 1.2V lithium battery or 1.5V dry battery)- Receiving board: 3.6V-10V (3-6 1.5V dry batteries, or 3-8 1.2V lithium batteries)- Distance: 100m- Frequency: high-frequency 2.4G, need bind, signal stability when use several sets together- Power: high-power, integrated motor driver chip on the receiving board, MOS tube drive efficiency is high, saving power. max. 2A/channel- Remote Controller Frequency: high-frequency 2.4G, automatic bind after power on, signal stability when use several sets together- Suit for differential engineering toy car, excavators, tanks and remote control boats. suitable for the differential turning of the motor on the left and right sides: such as the left and right side of the track, such as the tank excavator, the crawler robot, and the remote control boat with two propellers left and right, the high-power long-distance toys.To the frequency (pair code) method: press the back and right buttons of the remote control at the same time, and then power on again (note: must press the two buttons and then power on), at this time the transmitter board indicator Flashing, enter the frequency mode (if it has not received the power on the board for 15 seconds, it will automatically exit), and then the receiver board, then you will see the receiver board and the remote control light flash 3 times, indicating pairing carry out. (If multiple sets of transceivers are simultaneously matched, remember that you can only set one set at a time, and all others must be powered off)Note: If the frequency is successful, the next time you use it, you don't need to use the frequency again. If the transmitting board or the receiving board is lost, you can use it again. A remote control can be paired with multiple receivers to control multiple receivers.Using:The function of each button is as follows: (One button will turn the two motors tog
