I had a long-ish post all typed up, and our company switch craped out, so I lost it.

If I had no equipment and was a newby to the hoby and knew nothing, I might go with 2.4

Since I have a 72mhz radio, I am inclined to stay with it for now.

If I had 5+ planes I would definatly stay with it in those planes.

Since I have friends that are amateur radio operators and would like to join their fun as well and there are only 2 people on 6M at the field I fly at (popular field in Houston, so there are many fliers), I will be going to 6M. I seriously doubt there are many people across the entire US on 6M.

As an aside, I was speaking with a Jet guy here, and he had issues with his 2.4 car radio where it would loose pairing after a few minutes. So the car would run fine, then suddenly no control. it would not repaire until the reciever and radio were both power cycled. This means you lost all control of your plane and won't get it back. On 72, if you lose control, you have a chance of getting control back. To make it worse he sent the radio in to be fixed and they kept sending it back saying it was fine. Yes it was if you only used it for 1 minute, but if you tried to use it for a race, it would unpair in the middle of the race. They eventually did get it fixed, but this ruined his faith in 2.4 for his jets.

I would not mind trying 2.4, but for me there is other alternatives that look better for me.

If you do get the 2.4, I would recomend doing a multiple direction radio check where you test the plane in many different radio to plane orentations, as well as leaving both the radio and plane on for 30 minutes verifing it will stay paired.
