A ducted RC airplane has both the motor and 'propellar' within the body. Technically, the 'propellar' is more of a multi-bladed or faceted fan, and the part of the body within which it's contained is referrred to as the 'duct'. The whole assembly is then referred to as a 'ducted fan' RC plane, which has been subsequently referred to as a ducted RC plane. A non-ducted RC plane would be a conventional plane that you might be used to seeing, with the propellar plainly visible.
Each type of HVAC system falls into one of two categories: ducted or ductless. A ducted system utilizes a primary unit to propel air through a network of ducts, regulating the temperature of a building. Conversely, ductless systems operate without air ducts and employ alternative mechanisms to disperse conditioned air within a given area.
