FrSky has succeeded in introducing a transmitter at an entry level price that outperforms many of the best name brand systems on the market. You may worry that the quality has been cut to keep prices down. Compromising quality for the sake of price is not the FrSky way. FrSky may lack a fancy ad campaign and huge marketing budget, but they do not skimp on the hardware!
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 at the aircraft. Taranis will alert the pilot before signal quality becomes critical. This saves planes and makes the hobby much safer
