If I was in the market to buy a new top of the line radio I would be looking at the new 18 channel radios available. Lots of bells and whistles, and more channels than I need so that allows plenty of room to grow for whatever model may come along.
So there are two choices available, Futaba and Spektrum
Futaba wants $3000 bucks for their version.
Spektrum wants $800 for their version.
Hard choice, eh?
