This is a good app, with one problem. The tail sensitivity is way too high - to the point the helis are unflyable for anything but low rate simple hovering. Try to fly in high rate, and it is nigh on impossible to fly a figure 8, let alone anything more complex. Have flown real helis for 4 yrs, using three different flybarless systems, and none of them fly like this thing. Have emailed the developer multiple times and he isnt interested in fixing it. Wasting your money, especially for the price you pay for each model.
