I've seen the hobby take a jump and leave some equipment obsolete before it's time. This happened when we shifted from the colored flag frequencies to the channels in the mid 1980s. I also think this jump was responsible part and partial for the demise of many prevalent radio manufacturers of the time (Kraft, EK Logictrol and Proline, to name a few).

As we all know, the hobby does change over time. Equipment constantly becomes obsolete as new stuff comes on the market which is better, easier to use and offers more bells and whistles. The obsoleteness only occurs due to market demand: Do you remember radios which didn't have servo reverse? Do you remember when the truth was you had to build them to fly them?

I'm not saying 72 MHz is dead! However, I think any new radio I buy will be 2,4 GHz spread spectrum. I think I am intuitive enough to see where the hobby is heading and know what's going to happen! By the way, the first starter radio I bought cost $350.00. It was a Kraft Gold medal 4 channel. This was in 1968.
