Latency and all that

Latency, or how quickly a servo responds to a control input, is the latest marketing buzzword in R/C. It all seems to have started with claims in the Spektrum ads, and now everyone wants to know how their radio performs. It does have real relevence too - the latency of my Multiplex 4000 is visibly worse than other systems I've owned, to the point that you can easy see the delay on the bench.
