With radio-controlled aircraft, such kitbashing can be done to either kitted aircraft as they are being built or more often, so-called "almost-ready-to-fly" (ARF) aircraft to change their appearance or flight characteristics to suit the owner. This can even extend to "plans-bashing", where a plans-built model has its construction plans partially re-drawn by the builder, either by hand or with CAD software before any part of the model's airframe has been fabricated from raw materials.
