High-quality materials, exquisite craftsmanship, safe, reliable and durable, long service life, complete specifications, convenient and flexible use, and better cost performance.

27mHz 4-channel 8-button remote control set includes: receiver + remote controler set (and antenna, screws), Battery not included.

The remote controler is available in Black or Orange.

Four channels that can control 2 small motors forward or reverse at the same time.

It's a great little accessory for cultivating and learning to make remote control cars and such!

Note: This is for making remote control cars and so on, not for making remote control aircraft, can not use lithium batteries and high current!

Tip: Firstly the rated voltage is 4.5v! Please guarantee! Secondly the motor should have a soldered capacitor, at least a 104 capacitor! Anti-interference! So that the remote control distance is good performance! If you use 3.7V, the motor is not welded capacitor, the remote control distance will be affected, 3-5 metres is normal! The problem of button failure is to wait for a good pairing and then operate or reboot it will be fine!

With the motor, the motor tail please weld the 104 capacitors, that start easily, and anti-interference!

The remote control uses 2 No.5 batteries, 3V voltage; the receiver board uses 3-4 No.5 batteries is good, that is, DC4.5-6V, the best is 4.5V, you can buy the shop three battery box, do not use the rc aircraft lithium batteries, it will burn off the circuit board!

Frequency: 27Mhz

Remote control distance: about 12 metres (we actually test this distance, usually about 10 metres, it is enough for the car.)

Receiver output voltage: 3V, so can only use 3V can start the motor, such as 130, 140, 260 and other small motors.

Wiring Method:
The red wire connects to the positive pole of the power supply, the black wire connects to the negative pole; the 2 yellow and blue wires leading from B and F connect to a motor, the 2 green and white wires leading from L and R connect to a motor, the white wire with the circle metal ring is the antenna (the antenna with the pair is connected to this).L, R means wiring left and right steering motors, B, F means wiring front and rear motors.

Remote control size: approx 120*85*45mm(L*W*H)

Receiver board size: approx 42*27mm (L*W)
