I like the 72mhz for now, its all getting way cheaper,I can buy much less expensive RX's for them.

My channel seems to be always open. It just makes sense for ME to stick with the 72 and get while the gettins good

If I went to a lot of fly-ins or had a lot of members always at the field, I would look into a 2.4 but here in the sticks, on a good day we have 5-6 at the field normal is 2-3.

Guess I am trying to say evaluate your situation and go with what works best for yourself.
