New long range module for Turnigy 9X 9Ch Transmitter or other JR Radios.

Long range JR UHF radio system 265 USD

The new UHF RC system is based on Ham band and neighbouring band from 400mhz-470mhz, with the frequency hopping technology and frequency sweeping technology, you never need to worry about losing control of your precious plane.

Have short range trouble? this LRS has a range beyond your imagination. with a bad antenna, you may still get 20km range in the air, and with a super good 1/2 wave length one, you can even get 60km in the air.
