Why did you bring this up
I fly 72 and have never had a problem. Check the board, ask around, do a range check and you will never have a problem. I fly with a JR7202XP scanselect with scanselect RX. I love it so much I went out and purchased a 2nd because of how solid 72 is. I will probably never go to 2.4 unless I have to and they stop making or repairing 72 products. I see nothing wrong with 2.4 I just do not see a need in it for me.
