F450 uncontrollable in stab mode

Hi there

First of all, this is not a serious project. It is a school project where we wanted to build a drone out of spare parts, so no expensive or critical hardware was lost, but i had a spare pixhawk from another project, so we decided to use that. When we got it into the air, it flew fine for the first minute or so, but suddenly it started throtteling up while in poshold mode. Even when i switched to stabalize mode it was throttling up, very aggressively. It went out of control and flew into a tree…

Can anyone analyze the logs?

Check your vibrations and check your compass too.

Indeed the vibrations levels, particularly Z, are very high. Prop balance and consider how the FC is mounted.
