A better test of crawl mode + optical flow + sonar + Baro. A longer precision approach to a tree with the tractor beam. I can easily adjust the distance with the 5th ch knob while all systems are taking care of the pos hold. I consider this mission accomplished. Maybe some further fine tuning but nothing further is necessary. I will probably post a couple more videos of a precision approach to some objects and a cliff.
