Currently running master with a custom hwdef.dat to get 3 uarts on revo-mini, frsky passthrough telm, wifi telm and gps. Its working well, Tridge fixed the compass orientation so no longer getting compass problems when rotating it about with the motors un powered. However often get ekf failsafes when flying, due i think to compass interference. Hard to remedy on a 180 size quad, everything has to be close together. When it goes into loiter correctly it is extremely good.
I have fitted a current sensor with the hope of doing a compass mot calabration. However when i try from either mistion planner or Qgroundcontroll. It just says failed.
Have tryed through the MP command line too but it just returns rubbish.
