Hope you get it sorted out. I've got a 450 on the bench now. I'm a newb so I'm getting Mark Graves to set it up for me. He's the setup guru if you need some assistance. Come on by the store and he can test fly it for you and get it totally dialed in if need be. I'm not flying mine till he does! I've seen enough wadded up helis brought in that should have been set up properly so as to avoid the walk of shame
Good luck and keep em' flyin'!
