Bought for my son (8 years old) to learn to fly. The default control ("beginner" mode) is very sluggish, so it's better to immediately switch to H mode (left side button), otherwise it won't fly even against a small breeze. After switching rulitsya quite normal for study. Convenient gas - itself maintains the height. A convenient function to turn off the propellers (both joysticks down and to the center), because when landing in tall grass with the propellers turned on, it winds the grass around the propellers. PS In case of flight, I wrote my cell phone on it.
