After looking long I bought the G-2D -Brushless because the price compared to others was very good and the control is least accommodated in a housing. After the first test with only one battery, I was disappointed all "floundering" in front of him. Immediately contacted the dealer, who offered immediately answered and Exchange O. Money back. After I had grown Camera G-2D then ran halfway. Since I use a CamOne, I had to grow a counterweight and change the bracket. The Gimbal must be balanced with the camera somewhat, otherwise not make it to keep the weight off the drives. I run the Gimbal now under a Phantom 1 and it works just fine. The adjustment of "Roll" and "Nick" via the F2 port of Phantom I have not yet tested. The settings of the gain and the gain portion I have not changed due to my poor English skills. It works so well without very good. If the company would Walkera mitliefern a German manual, explaining that on these issues, that would be very helpful and would not come to the wrong decisions as calls and returns for customers.
