P4 Stuck in Aircraft Warming Up.

[Ingydrummer]

After replacing FC board and fixing the IMU error, the Aircraft Warming Up mode will not go away. Can't take off. Im at the end of my rope with this thing. I left it on for nearly an hour and still wont clear and go ready to fly...

there is something about cooling craft down before imu cal that allows heater enough time and amps to perform imu preheat. cool down bird, perform imu cal with fully charged(best) battery. If no....then we try finger test(component warms up)...

Found the problem, was a burnt power ribbon from FC to main board.

Good to hear you have it sorted. Will file that one away.
