Agree, mostly, and trim tab rc radio operation is dated. Switches and knobs are superior. To clarify, did not mean that one rc radio is intrinsically better than another. Did claim that the rc radio that “works smoothly”, every time, without operational glitches is the rc system I would spec into a build, regardless of how many channels offered. Just as long as there were enough channels for the tasks at hand. When the need arises, I will try out your recommends.
