Beardking, you won't find a better company to deal with than Vector Flight. I too have their Edge 540 and the 58" version of the Extra 300S. But I wanted to say that I have a 40 sized Sukhoi, of unknown manufacture, with a 61 Super Tigre engine on it. It was my first Sukhoi, and the really neat thing I noticed on the very first flight, was how they stay where they are pointed! You must pay attention at all times! If you're flying straight and level, whatever control input you give it, will take the opposite to bring it back to level flight. The Sukhoi is no self righting bird. But a real blast to fly, once you get over the shaking thumbs thing!
