Orestes just won the World with electric. Paul Walker won recent NATs flying electric. Electric is on par with the best of IC, in ways superior. David Fitzgerald flew better this year. Pilot. His piped engine powered up accurately where shape making most benefited. When the IC big blocks are working best, keyed to conditions, they appear to have more drive. Electric devotes will disagree. Perhaps the flick flick millisecond thrust changes enabled by the Igor System are blunted in their effects by the size (weight and aerodynamic drag) of serious CL Stunt War wagons. This years NATS made me think of airplanes as boats swimming in air. Steered through direction changes more softly than cars, for instance, stuck to to the road. Perhaps the millisecond changes enabled by electric power with computer enhancement will not dominate CL Stunt, after all. A friend said, however, that electric is now the sole power for serious RC Aerobatics.
