This is my first Operational Check Flight on the 550X. The ESC is set to governor mode, the 50% calibration has been completed. The idea here is to feel out the Idle settings/transitions, check the FBL flight style setting, monitor tail response and get a general feel for how everything works together. With all of my "out of the box" settings this check flight went GREAT...next its time to take it to the field where I can really turn it loose, try out some 3D and see what this BEAST can do :)
