Hi - I am going to be flying my Phantom from a moving fishing boat on Lake Tahoe. In the event of a RTH incident, I am trying to assure that the Phantom will return to my position, which will be moving around, rather than to where it took off or to a distant shoreline on a big Lake. Am I correct to assume that the solution is to set the RTH feature to the Controller in the Home Point Settings, and to turn off Course Lock for low flying? My biggest concern is something unexpected happening and the Phantom flying away to some distant point without me. Anyone with any other advice would be welcome. Is return to the controller location a reliable failsafe?
