Why my zero pitch keep changing. Sometimes when I do full throttle and 0 throttle and back to mid stick, it's not zero anymore. Sometimes after turning off and on again, it's not zero anymore. It can be positive pitch or negative pitch. It's give me headache setting min/0/max pitch curve.
I suggest you use subtrim on your Tx to make the ZYX see 0 at mid-stick when looking at the monitor screen. And also when Mikej said with the setup pitch curves.
