Bryan was not using the GO app, it was running in the background. He was using the Litchi app for a POI. The analysis data showed a CSC was done, the flight record form the GO app showed a CSC. The GO app went into low battery RTH and probably the Litchi app tried to keep the POI flight going. BUT ALSO, Bryan took off with 23% battey left to go do a POI mission. If he would have not taken off again with that low of a battery, maybe the GO app wouldn't have gone into low battery RTH mode.
So you should not be using two apps at the same time.From what Terry stated:
Lessons Learned: Pilots must maintain situational awareness by maintaining control of their aircraft, scanning the GO App for battery levels, alert messages, and take controlling actions when necessary. I believe that running both the GO App and Litchi contributed to this crash. I think taking off with only 23.9% battery also contributed to this accident. If Bryan says that he never touched the controls, then likely the two programs were fighting for control and flew the aircraft into autonomous CSC stick commands. Regardless, the motors shutdown because of a commanded CSC.
