The question for me is what is not so much the latency/speed of a flysky but what are risks of having this system compared to a Sanwa etc. Are trim settings more solid and don't drift, for instance center trim. If that drifts you will never be able to drive with consistency or speed.
I guess what Im saying is are we getting our moneys worth when we buy a Sanwa Futaba Spektrum?
I figure if latency overall is less than say 6ms and the settings dont drift you should now focus on setup and driving
