Pattern planes are designed so they fly as close to perfect as possible. Every detail about how they fly is focused on allowing a pilot to perform extremely complicated precision maneuvers with as little correction as possible.

Real pattern planes have a wing span of 2 meters or less and a length of 2 meters or less. This dimension was used as its the height of a European door frame (I'm not kidding). Designers stay close to the max dimension as the bigger the plane the easier it is to see and judge.
