This LRS system is well made and perfectly fit JR radios .

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

This module fits perfect for the well known Turnigy 9X 9 CH Radio 55 USD.

It will of cause also fit all other JR radios.
