Just got the March AMA magazine in the mail. In it there is an article on the DX7. AMA makes the recommendation that clubs provide flightline controls for spread spectrum radios; suggesting multiple pins and identification spaces on the board for SS. They give two reasons as rationale:
1) Keeps members in the practice of getting a pin.
2) Provide a method of flightline control.

As VP of the local club and event co-chairman for Michigan Jets I've been in on several discussions regarding this topic. Our initial feeling was to do nothing at the field since only a few members have SS at this time. For events impound the radios as a means of flightline control. Our flying season in Michigan doesn't start for a couple of months yet so we are watching what others are doing and are open for suggestions.

The AMA recommendation does make sense. Regarding #1, I can see it now, some guy gets use to flying his SS for a couple of months then shows up one day with a plane on 72 mhz., forgets to pull the pin and causes an accident. Regarding #2 for normal everyday flying flightline control is not an issue at our club, however it is needed at events and it is good to let others know that someone is flying on SS.
