Hi mate I have the black angel too , its a nice heli its longer then the align 450 , I fitted the DFC head but there is so much slop the blade tracking in flight was an inch out , so now fitted the FBL head ,but mine has small follower arms , but is a nice head no slop and blades Track really nice , one thing I did find while testing the heavy blades made the heli super stable so I now used the 26g blades http://www.ehirobo.com/rc-helicopte...p-450-class-320mm-main-blades-1081159645.html
