Some friends of mine just sold their's here in the USA, and it's headed back to mother Russia. I have some flight experience with it, and it is most def. a kick in the pants alright, in more ways than one. It will handle all the acro you can take. Great for IAC competitions, my friends flew their's at the advanced and unlimited levels (respectively).
The downside is it is a real SOB to find spare parts for. The one my friends just sold came with a 2nd motor for just that purpose (to keep the one in it running). High cost to keep maintained, but when/if running will take anything you can throw at it.
If you can keep it running, you will fall in love with it. That "if" is a real challenge. Make sure you have a means for getting spare parts before you purchase it. Otherwise, you may spend far more time looking at it than flying it.
