Villa has indirectly made a point. John, those who do not teach others very often will not understand the benefit of your wireless set up. I do, and I plan to get one or make one myself soon.
I'm still flying on 72mhz and most of my students start out using my equipment. I mainly use a T6XA and a T6XHs as my master and Skysport 4F for my buddy boxes. I'm going to have to check see if Futaba makes a wireless set up for 72mhz, if not, I may have to get a 2.4 system just for this purpose.
