I own it; my first payware choppa. I cautiously recommend it if you are a first time helicopter pilot. It is a bit of a handful landing. Lot of crashes.
But I fly it now competently-even in light winds. I use only a Saitek throttle for collective and Logitech 3d Pro stick. Everything set to '0'. As per instructions I use 'experimental checked in settings.
I mastered it and it made me a better copter pilot because it is a very light choppa. Don't forget to check your weight in payload. As I recall it was too light to be human weight and I found that made a difference.
Knowing what I know now -it's a solid little package....and a challenge.
