RMILEC 400-470MHZ UHF Frequency Hopping LRS for JR Radios

RMILEC 400-470MHZ UHF Frequency Hopping LRS for JR Radios

This LRS system is well made and perfectly fit JR radios . For other radios, you must do some wiring work to get ppm, V+ and GND from your radio and the system will work.The new 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.
