I know that the "Best Radio" is really a subjective question but.... I wanna change out the stock radio for something programmable to change things like Yaw rate with expo functions. It's pretty pathetic that I haven't bought a radio tx in forever. Last one was a kopropo mars for racing cars and I have about 4 old analog airplane radios. My local dealer does Spektrum and seems pricy. Futaba has been around forever and I see the Frsky thread. I just have no idea whats really good for quadcopters?? Specifically things like the throttle lever on the stock radio is nice that it recenters when you let go instead of the usual indexed mode. Is it possible that some have that option while other don't? I also wondering what other specific options radios have that other simply don't? Thanks for any input.... I know this is a very broad question!!
