In early childhood development, there are surprising “windows of opportunity” where languages can be learned rapidly and perfectly in a manner that is forever lost to adults. This “opportunity lost” is a result of sensory striatum deprivation. A cat will remain forever blind if kept in the dark during the first months of life even with perfectly functioning eyes – use it or lose it! Rudder usage follows this same pattern in pilots. If it is not learned and mastered very early, it seems to be forever a mystery (see early maneuvering blog). This deficit creates a pilot that will always be struggling to achieve positive control in the aircraft.
If you have not taken some dual in a tailwheel aircraft, you really have not experienced flying as it could be. This experience will truly open your eyes to full aircraft control in three dimensions. Many pilots are still regrettably two dimensional and are frankly missing a lot of fun (and “rudder deficit” is also “control deficit”).
