I just wanted to say that it is fine to use ur older radio, if it is narrowbanded, and with the advent of NIMH, or Lipo batteries, u can get newer batteries rated at 2000-2500 MA for ur TX, and have trouble free operation. I still fly everything i have on 72MHZ, and am one of about 5 other flyers in our club that still use 72. We have 100 members, and about 45 active flyers, and most on 2.4. Most days at the field, I am the only one on 72MHZ. I have a preference for the Gold Futaba FG series of TX, have used them for 25yrs, and have never had a glitch on any freq I use. I upgraded to 2000 Ma NIMH batteries in all of them, and have picked up these radios for as little as $15.00, all gold stickered. At least, check, or replace ur battery(1st & cheapest option), go fly, and see if u still have the interest and enthusiasm u once had. Here's a pic of what I am using. Best of luck- Dean
