I had the U1 130 thousand dollars that I bought at the time of the G1 cloud, which was very bad, and the first shot was not to be able to fly with the GPS mode, and then the landing gear had a problem. Second, the power efficiency is very low. Four 16000mah batteries can only fly for less than 8 minutes. In fact, they do not mount heavy cameras and lenses.
But G1 works very well. After zooming, it is very stable. Neither freefly nor DJI can do that.The main problem is that its image transmission distance is very short, which is equivalent to controller distance.
