Parameter index

  • Product type: ETB4II -2.4GHz
  • Transmitter Frequency: 2.402-2.480GHz
  • RF power: <=100mW
  • Voltage: 9V~12V
  • Electric current: 200 mA
  • Modulation: Direct Sequence Spread Spectrum
  • Land R/C distance:200m
  • Air R/C distance:400m
  • 20 sets of the radio system can be operated  simultaneously without any interference. 

More features of the ETB4II-2.4GHz:

  • Fully proportional
  • High quality joystick
  • Servo reverse function
  • Low voltage alarm
  • Remote control

Using advanced technology of digital frequency hopping and inserting address code, the limited spectrum can be fully utilized to avoid interference with the same frequency.

Using highly-integrated frequency synthesizing technology, the microprocessor can automatically preset and set frequencies. Therefore, using a set of 2.4 GHz remote control system, there is no need to change crystal. 

With new digital technology, 2.4GHz remote control system is no need to change crystal.

Power amplifier works only at the time when data is being transmitted, thus shortening the working time, so as to extending the using times of remote controller after a charge. 

2.4 GHz wireless remote control system has short antenna length. The length of the antenna is usually 1/4 of the frequency wavelength. As the wavelength of 2.4 GHz frequency is short, 2.4 GHz equipment can be operated more flexible than regular remote control devices.
