I have a new ballence bot on pixracer with stepper motors working fairly well still a work in progress but have had an issue with the aux 7 pwm for its use. I have a 7 character. Tx with spectrum sat rx and all channels show on radio calibration but in basic parameters the option is not highlighted (blanked out). I have tried different versions. 3.5 dev and now 3.5 rc1 with the same affect. Not sure if its pixracer not supporting 7 channels. Any ideas would be great as I want to use the aux for arm disarm so I don’t have to use a telem. radio.
