All the heli's on g2 (except the fixed pitch helis of course) will hover inverted without editing them. You just got to flip the idle up switch. If you got the usb version its the 3 position switch on the top left of the controller. You'll know you got the right one when the blades rpm's go high, and stay high when the throttle stick is moved all the way down. Then your ready for invert and 3d.
