RE: rx choice
You know, that's a good point. With the move to 2.4 GHz, a lot of our 72 MHz pilots are moving over too, which tends to free up some of the bandwidth for congestion on that frequency.
But, the one big advantage to 2.4 GHz is that the pilot does not really have to impound the transmitter or rely on frequency pins to fly safely.
Something to consider.
