I have 2 pots that I am trying to mix at the TX side. The RX side drives standard hobby servos.

If the joy stick is viewed as 4 compass directions. Moving the stick north and south moves the 2 servos in unison the same amount same direction. But going E and W only moves one that corresponds to East and one that corresponds to West.

I have tried IF then conditional statements with dead bands to detect the proper mixing conditions but it seems to fall out of these conditions because of the sloppy nature of the pot/joy stick mechanics.

Does anyone have a cleaver way of finessing these issues?
