The model ID switch within these Spektrum radios is like 5 to 10secs. How long does it take to switch the Servonaut system or CTI?

 Ok i see, thats one to do it.
Both the servonaut and CTI is by a push of a 2 or 3 pos switch and you have switched model, i like that and the fact that you only need one radio.
