My Pixhawk is installed on Mariner quad (500). With the version 3.2 it has many nice flights, with very good ALT Hold control and AUTO flights.
After recent upgrade to 3.3.2, it changed its behavior: in Stabilize all is OK, stable and smooth control, hovers on 50% Throttle. When switch to Alt Hold, it starts rising up at full throttle! When switch back to Stabilize, all is OK with the control. Sometimes the rise up is hard to compensate with the trottle....
Looking at the logs, all seems OK, except the inconsistency in the IMU - accelerometers 1 and 2 shows different phase after switching to Alt Hold.
Do you have any explanation? Hardware fault or 3.3.2 software bug?
The last test flight log is enclosed.
