In "The Contra Drive for Pattern," Justin Wells discusses the shift in RC aerobatics towards electric contra drive systems, which have become the dominant power setup for Pattern airplanes. These systems, developed specifically for Pattern pilots, eliminate yaw and P-factor, enhance braking, and improve energy efficiency. With approximately 90% usage at the FAI F3A World Championship, contra drives are gaining popularity due to their affordability and ease of operation. Common types include planetary gear drives and belt drives, with propeller sizes typically ranging from 24 x 20 to 23 x 22. While contra drives simplify setup, skillful flying remains essential. New pilots are encouraged to start with single drives before transitioning to contra systems.
