RC Helicopters - 6 Channel Radio Control Helis

Whats the Difference Between a 6 RC Channel Helicopter and a 3 or 4 Channel Remote Control Heli?

The 2 additional channels give skilled rc pilots the ability to perform some really cool 3D aerial movements! These highly aerobatic maneuvers include loops, both inside and outside, as well, the 6channel rc helicopter can literally fly and hover upside down!
