Just learned to hover on the that bird. The Concept 30 was very stable and fun to watch "float". It had an old rate gyro in it that was squirelly but not impossible to get used to. I was just getting used to hovering when i stripped the main gear. The parts are too hard to find. When I came across the main gear on ebay it went fast and for 25 dollars. If you get it you'll want to find new blade grips for it. I got the kyosho nexus blade grips to fit. those are discontinued as well, but are still easier to find than concept parts. Good Luck!
