Here is the background:
I have been flying my fixed wing for over a year without any major issues.
FC: Pixhawk Mini running QGC.
Recently it was too hot in Kali and my motor flamed out, so I am upgrading it to a bigger motor and ESC.
I tested and calibrated new ESC and motor before plugging into FC with the same receiver and radio for the plan and everything works fine.
Now that I wired up esc and motor on the plane with FC, its giving few seconds interval beeping noise while searching for satellites. No change when I arm with the safety switch, but as soon as I arm with throttle stick to the bottom right it starts to beep constantly with no response to my throttle movement.
Do I need to re-calibrate my radio with QGC hooked up to the FC?
