Been a CX owner for several months, just got the cp pro about a week and a half ago. The pro was setup perfectly out of the box. I could not believe how smooth it looked and sounded when spooled up. I have put 14 packs thru it and have not broken anything yet. Not bragging just suprised myself. I was expecting it to be extremely difficult to fly and it wasnt nearly as bad as I thought. I took my training gear off around battery pack # 9 and can pretty much hover tail in and spot land it. IMO the most important thing to know before you fly is to be VERY light on the controls. That thing is quick, not unmanageable, but quick and man is it fun!
