Lucky flight


There was 1 battery change which produced very stable flight with very slow velocity updates on the order of 1/2 second. Yaw was non functional. Only pitch & roll worked. It could have been a lucky compass alignment.

There could be an unknown configuration error during the battery changes, making it unstable. Manual flying is still stable, weeding out the stick voltages. There could be a random delay in the video.

There's also the random heading offset during battery changes. The battery wires are bent differently for each battery. Different current flow inside the battery or different bending of the fuselage can also explain it.

The analog gyro has a huge noise offset when the motor starts, making it completely worthless. It could be the LDO, the Vref, or vibration, but there aren't enough batteries to do any testing or make any conclusions. Those USB chargers take many hours.
