A while ago, I added a 6-position switch to my X9D (OpenTX 2.3.5) and set it up as S3. On the radio itself, I’ve selected S3_1 to S3_6 to select the OpenTX flight modes and named them in the same order I have selected on the flight controller (I know this is not needed to change the actual flight mode, but I wanted it to be like that).
Now I want the same switch to select flight modes on my ArduCopter Multicopter (Pixhawk with S-BUS R-XSR receiver). I’ve mapped S3 to channel 5, which seems to be default for flight mode selection on Copter. But the PWM ranges between switch steps do not “fit”. I’m not sure which way I should choose to correct this. With OpenTX and some logical switches or with a curve? Or even change something on the flight controller?
I’m looking for the “recommended” or least complicated way to do this.
