Why do we need to know who is flying? What control do we need?

The 9-10 annual jet events I have attended each year for the past 7 years needed control for frequencies primarily; but secondly it was needed because too many people held on to the frequency pins longer than they were suppose while working on their planes at the pits which led to the need to know who had the pin. None of which is neccessary with 2.4Ghz!!!

Nobody is acting like 5 year olds here, we are just moving into a new phase of our hobby which no longer requires control or the need to know who has what pin. Impounding is simply not neccessary unless there are other reasons I don't understand.

In addition to all this I can name three events where the wrong frequency pins were handed out to the wrong pilot by the guys at the impound, or frequency pins were taken back to the hotel with the guys after a day of flying. This either delayed the start of the event the next day or they simply made up a new pin hoping whoever had it didn't use it when they returned that day (very scary). I don't really call this control of an event but at the time this was our only choice so we had to live with it but now we can finally move on...Well some of us can I guess!! Gary
