Nope! Allot depends on where you are. Different areas of the country have issues with radio frequencies. Just like the old 27 mhz was hit with CB traffic. I still fly with AM, FM and PCM. I do not own any 2.4 stuff. To expensive to switch over. To each his own.
Total out just one plane and you will have met your budget cost to switch over to 2.4 GHz.
"A radio that will not lose signal"? They all lose signal but with the 2.4 GHz systems you are flying with a "failsafe" mode and multiple receivers for redundancy. The best failsafe for the 2.4 GHz systems is to have a battery(s) of 6V and adequate capacity and discharge rate so they do not drop below 3.4V under a load.
My 72 MHz stuff has slowly fadded away but I still have 2 systems on the shelf collecting dust.
