*VSKYLABS is an independent developer, not affiliated with Laminar Research or the X-Plane brand in any way. RCE is a third-party add-on product developed for the X-Plane 12 platform.
X-Plane 12 by Laminar Research is the world's most advanced flight simulator engine for personal computers. Unlike conventional simulators, X-Plane uses blade-element theory to calculate flight forces in real time, making it an engineering-grade tool rather than a game.
X-Plane is trusted by defense contractors, aircraft manufacturers, air forces, NASA, and major airlines for applications ranging from pilot training to concept design and flight testing. The FAA has certified it for logging actual flight hours toward pilot licensing; that is the level of physics fidelity that VSKYLABS RCE is built on.
RC-Elements (RCE) runs on this engine. Every flight characteristic you experience in RCE; the way a swept wing 'bites', the way a slender delta bleeds energy, the way a counter-rotating prop behaves on climbout, is calculated by the same physics core trusted by real-world aerospace professionals.
X-Plane and RCE is not arcade RC simulation. This is engineering-grade RC simulation.
