Hi Gordy! Good question about max number of 2.4 transmitters. I seem to recall we exchanged some notes on this. To answer your question, I never thought the number of concurrent transmitters was unlimited. Frequency control and channel conflict are handled by the radios, so I don't have to manage it manually. And all makers, except Futaba, have been pretty public about the max number supported by their particular implementation. And I doubt the average 2.4 user has given much, if any thought, to the max number of concurrent transmitters. I would bet the typical RC user will likely never see more than 20 transmitters in use at once unless they are contest flyers, which most are not. Even then, I would bet most contest flyers would rarely see the need for more than 40 on at once. The largest contest I have ever attended had 42 pilots, almost all were on 72 Mhz. In this case, there were no channel conflicts. Yet I doubt there were ever more than 20 sets on at one time. The Heli event was a big exception but even with that we don't know if there were even 50 transmitters on at once, only that there were 500 transmitters at the site. Until we start to see more events like this, it is going to be a while before we know if the max number of transmitters is even an issue, only that there are apparent limits by brand. Gordy, you attend a lot of contests, some of which are quite large. Why don't you organize a test at one of the upcoming contests. See if you have enough 2.4 sets to run a saturation test. I would be very pleased to hear the results of that test. Ed Anderson LISF
