The return to home on the YS-X6 is very impressive and particularly how stable it touches down and then turns the motors off. Even in full manual mode the copter hardly wanders at all.
The main down side of this ZeroUav system is user manual is absolutely appalling and virtually useless. Also the GCS for PC is not very intuitive at all. The wording translation from Chines in many areas is very bad. For the price tag this should be better than it is. The waypoint upgrades are not cheap and you need at least the basic upgrade from 4 way points to 16 waypoints to get auto power off on the motors.
This weekend Ill go try out some auto navigation flight tests.I have to say that apart from the poor documentation, the flight behavior and stability is very impressive.
