When Futaba finally(!) released the TM7 2.4 module and receiver combo, I tried one out in my 9CAPS. Flew my old dependable Big Stik, because I was extremely familiar with it's characteristics, and I was sold right then and there. Within 3 weeks I'd sold all my 72mhz equipment - 24 rxs and several txs - and bought 10 2.4 rxs with the money. Within three months, the 72mhz stuff lost another 40-50% of it's value. When the 10C came out, I sold my 9C and upgraded for a out-of-pocket cost of less than $250. No regrets whatsoever.

If I'd waited until now, it would have cost me substantially more money. I got ~$1000 out of the 72mhz + 9CAPS on 2.4, and spent ~$1300 on the 10C and 2.4 rxs. Today, I'd struggle to get $500 out of the old, and the new would set me back $1600.

The advantages to 2.4 are worth the $ to me. I started with 27mhz AM, then 72mhz AM, FM, 512PCM, 1024PCM - and the 2.4 is so far superior I can't find words....

I'm by no means a high-dollar flyer, but it's not hard to get $1300+ wrapped up in a 50cc gasser, or $500+ in a .60-sized 2-stroke warbird. Putting the most solid radio connection in the plane just makes sense to me, even if it costs $70 more - which it doesn't. The 8 channel high-speed 2.4 rx costs less than I used to pay for 8 channel PCMs. The "feel" is amazing with 2.4.

The peace of mind that comes with knowing I won't be shot down is exceeded only by knowing I won't shoot someone else down. If I want to spend an extended amount of time experimenting with the radio in the pits, I'm not pressured to hurry so someone else can fly. If some newby turns on or someone grabs the wrong pin or Tx or sets their dial-a-crash module to 47 instead of 38, I'm not picking up wreckage. If I screw up (yes, it could happen!) there's no harm done.

To each his own. I got out when I did for two reasons - once I tried 2.4, I was never going to enjoy 72mhz and secondly was the rapid decline in value of used 72mhz equipment. No regrets here.
