What it’s all about
When flying fast and agile mini-quads, the time to transmit control information from remote to flight controller plays an important role. Latency in the transmission forces you to anticipate every move and has an impact on the precision on the race track.

Terms such as MOS (Minimum Operational Sensitivity), and MDS (Minimum Detectable Sensitivity), are thrown around in military circles, but exactly what they mean in our world is not clearly defined.

Just to illustrate this, here are three different definitions of sensitivity, which can vary from one extreme to the other by more than 10dB in a typical FPV A/V receiver.
