Only what I've read on the forum and the video's that i've seen. I seems like it's hard on motors. Even tho it's a 4ch coaxal and has a 2.4Ghz Tx, I think that it's a little too high in price. Hobby People has it for just under 220 bucks. Go to this thread, in this forum and you can read all about the Extreme Flyers X350.
