During test flight and even on the ground I got many different errors but quad flies ok (almost)
- I am not able to arm quad in loiter mode, in alt hold mode it arms and flies.
- When switching flight modes on the ground with remote controller I got error (in Tower app): Flight mode switch failed
- During flight I got some EKF errors on screen in Tower app
- Differenece in voltage on ground and in the air is 1V! (auto review log reports: Test: VCC = WARN - VCC min/max diff 0.356104v, should be <0.3v
Including the log files, I cannot read whats wrong… Please help.
