FrSky R9 Range For Long Range Flights

The 2.4GHz radio connectivity link has been used for ages for Remote Control toys and other equipment such as drones. The reason for this widespread usage being that 2.4GHz has better bandwidth and frequency allocation to accommodate multiple transmitter and receivers in a vicinity without causing interference to each other and failsafes. 2.4GHz type transmitters provide decent range, a Flysky i6 transmitter provides few hundred meters and the FrSky transmitter can provide around a mile of range. The FrSky R9 Range is much, much more than those 2.4GHz systems, at almost 10KM of range!
