RE: YT International ADRENALINE
I'm involved with YT International, and we first flew the model at the British Freestyle Champs last year. Ali from Al's Hobbies had the sticks and threw it around as though he'd flown it for months, followed by several of the other competitors. The general concensus seemed to be it was as good if not better than many of the more expensive models competing on the day. I test flew mine last week, and can safely say I've never had an aerobatic model like it, incredible.
Have a look at YT's website for more info ytinternational.co.uk
