Here is another perspective. I held off on 2.4 when it first came out just to be sure it was going to do what the manufacturers said it would. There were some technical issues early on that were fixed quickly. Now the problem for me personally and perhaps a number of others is I am unemployed. While i still fly, i am flying on 72mhz and due to the fact that i do not have employment have no immediate plans to start the change over to 2.4. Please don't misunderstand, i would love to but when it comes to buying a new radio versus making a mortgage payment, you know where the money goes. I have flown 72mhz for many years and right now the plan is to continue to do just that. As far as being shot down. I was shot down once 20+ years ago by a newbie that came out to the rc field. That is the risk that remains but if you go to an organized field your chances of being shot down are at least reduced. On another point, the more flyers that convert to 2.4 further reduces the risk of being shot down on 72. IMHO if and when 72 is phased out we will be given ample notice to change over similar to the time frame given to go to narrow band years ago. I cannot remember what that time frame was but it was, as i recall, a significant amount of time.
