I'm using the latest FW but had big issues that it wasn't tracking properly.
For example, I had a house in the middle of the screen 400 m away, pushed the stick forward and the house would quite fast move away from the middle of the screen and finally out of view due to the fact that the drone was moving in one direction and facing in a another direction, it wasn't tracking properly.
The angle was maybe 10-15 degrees.
I landed the P4 and made a IMU calibration right away, I wanted the P4 to be warm so it would calibrate with normal flying temperatures of the electronics and also IMU.
I also did a compass calibration but was very careful to only rotate the P4 around its own axis and not spin the P4 around myself which will create accelerations and potentially mess up the calculations.
This seems to solve the yaw offset issue during flight, will need to do more testing to verify it.
I live at 61 deg North which means that the magnetic field has a steep angle and even small errors in the angles will create big heading errors.
