lucken, 3D (CP) helis will fly upside down, fixed pitch (FP) helis will not (at least not for very long). When inverted with a 3D heli, you reverse the pitch on the main rotor so that the "prop wash" now "blows" out the top of the main rotor instead of the bottom, keeping it airborne (for lack of a better explanation). With a fixed pitch (FP) heli, the blade pitch cannot be changed or reversed, so if you get inverted and try to stay that way, it will force itself into the ground ... inverted. Hope this clears things up a little.
