      1 1 Model airplane – generally known collectively as the sport and pastime of aeromodelling – here is not an aircraft model for the wind tunnel application. It is a small remotely controlled (RC) plane that is often designed by non‐aeroengineer traditional airplane enthusiasts and is usually built in a garage.
