The most important aspect for any transmitter is maintaining a rock solid connection with the receiver. FrSky is well known for the frequency hopping ACCST technology taking advantage of the entire 2.4GHz band resulting in excellent range and reliability. FrSky knows many things can affect the connection between Transmitter and receiver so RSSI (receiver signal strength indication) is incorporated into all telemetry receivers. The Taranis transmitter is continually monitoring the reception quality of the aircraft. The Taranis will alert the pilot before signal quality becomes critical. This saves aircraft and makes the hobby much safer!
