Iget a kick out of seeing these old threads and reading the doom and gloom of the passing of the 72 meg radios. From the impound of the last couple of IMAA events they are about 50/50 but in IMAC the 2.4 has about taken over. The different clubs or fields Ifly at the 72s are still holding there own. Seems not all weekend sport pilots have the ready cash to make the switch.
Iwould be changing my radio over to 2.4 but the cost of all the new RXs has kept me from the move. At this time in history Isee myself sticking with what I have for some time.
