For users of RealFlight G4 or newer, the older series of 'Add-On' packs have been reworked, with several aircraft receiving updates, and can be downloaded freely from the RealFlight website.

Knife Edge Software also develops packs containing additional content for RealFlight, each of which adds new airfields and additional aircraft.

RealFlight requires the connection of an InterLink controller, which is included with the software, in order to operate. The most recent is RealFlight 9, which included additions such as water and water physics, an improved user interface, more aircraft, more flying sites, and an improved 'InterLink Elite' controller. The software is released in 'generations,' with each new generation including major updates and new features. In order to create new visual models, the use of a 3D modeling application such as Autodesk 3ds Max or Blender is required. Within RealFlight, editing aircraft is limited to changing the physical and aerodynamic properties. The software also includes an airport editor and an aircraft editor to allow for the creation of new flying sites and aircraft. Included with RealFlight RC Simulator are various flying sites (or airports) and aircraft models, almost all of which represent real-life models. Real Flight Simulator (goes around with a few different names) is a commercial rebranding of an old version of the free and opensource flight simulator Flightgear. Note: Although RealFlight RC Simulator has a similar name to Real Flight Simulator it has nothing to do with it. The software allows for the flying of numerous RC aircraft, helicopters and drones so that the user can learn to fly RC, practice their skills or fly with others in multiplayer mode. RealFlight RC Simulator is a radio-controlled airplane and helicopter simulation software series developed by Knife Edge Software and now published by Horizon Hobby.
