And my question is, why would someone buy a computer radio with all these great features? Sort of like going back to wearing bow ties and high button shoes?? I bought my radio to get away from these old school set ups and have the mixes to use. The DX7 has the duel aileron set up in it's program but you have to use a Y on duel elevator servos. A Y harness is something we did before we had these nice radios with all the great features.
