Hi all, I was using APM firmware AC 2039  had success flying my QUAD. but now I want to urge the APM in my skywalker. plane load the 2.22 firmware to configure all the sensors and radio as usual and it works well. but when I disconnect the battery and reconnect the battery you lose all the configuration of sensors, radio (Tx) and ESC.

know why can this be happening?

some consideration needed to change ACM APM?
