I haven't really flown it a whole lot yet. I balanced the swash. I flew a few batteries. It is not as stable as the 300x, but it flies very well. (I only do sport flying and a small amount of inverted)
This is by far the best training heli out there I have been flying it for awhile now and took it out to the field for the guys to try out and they all loved it. I have been flying 450s and they have nitro 700 goblins they tried this out and just want one to train with because of how relatively cheep it is and it flys so good even in wind.
