I'm slowly rolling over to 2.4. I love my 2.4 ghz radios. Those who think 72 mhz is going to be around for a long time are only fooling themselves. The FCC has been wanting our frequencies for quite some time now. That is the biggest drive behind developing the new technology in a different frequency band. Eventually (say within 10 years potentially) the FCC will eliminate our use of the 72 Mhz frequency. And there won't be enough lobbyist left to stop it, as most of us will be switched over by then. If they are willing to make all TV stations to switch to digital signals from analog signals, then forcing us to all switch to 2.4 ghz will be nothing for them.
They will sell our frequencies to other people for other uses.

Having said that, here are the benefits of my 2.4 (DX7).
A) Model match
B) No shoot downs
C) Eliminates MOST outside intereference problems
D) Makes setup of gassers easier, and more bullet proof (let the flaming begin)
E) Shorter antennas is nice (especially on the rx).
F) Shorter antenna on the tx, however, makes it a bit awkward to hold until you get used to it.
G) Allows me to work in the pits with my radio without worrying about who is flying, so when the skies are clear, I can fly, and not work on my planes!

There are more, but that's the short list. And I have to seriously doubt the claim that low voltage lockout has caused more crashes than 2.4 has prevented. There is no way to substantiate that claim. What I do know, however, is that since I've went to 2.4 NO ONE has shot ANY of my planes out of the sky, and I'm sure EVERYONE who owns a 2.4 radio can make the same claim. Also, I've NEVER had a low voltage lockoutbut then again, I always check my voltage. If you get sloppy, and don't preflight your planes before every flight, then yesyou could crash from a low battery, or even an elevator clevice that is broke/loose, etc. That is not a 2.4 problem, that is a modeler being lazy problem.
