RE: Future of 72Mhz
I think it is only logical that 72 will not be available to us. One of the AMA's most important benefits to us Rc'ers is that they lobby to keep our frequencies free. That is not really necessary now with 2.4 and to be honest other than having the cash, there is almost no reason to stick with 72mhz. I have not bought new radio equipment yet because I cannot afford it. As soon as I can though I will outfit all of my larger planes with 2.4.
To me one of the major benefits is not having to secure your frequency at large fly-ins where you have to wait for your frequency. That my not be as much of an issue with the move to 2.4 but I also do not want a $3,000 that took a couple of years to build get shot down by someone not paying attention with their transmitter.
