Mr Junkie ... what sort of plane do you wanna fly? My personal experience with the Rossi 45 is that she is good for either full or low throttle only. Never tried her for 3D so I can't really say much. As for fast, the Viper is fast and not too costly. Do check the mounting if you wanna purchase that plane. Any other plane is about the same. I had my Rossi on a WM Sky Raider Mach II, she was decently fast.
