A short introduction:
VSKYLABS RC-Elements is an advanced engineering framework that effectively turns X-Plane 12 into a standalone RC flight simulator environment. Developed explicitly for real-world RC (remote control) pilots, it delivers authentic and highly engineered RC model airplanes and helicopters physics, offering a robust, study-level RC flight sim option in 2026 for professional pilot training and radio-control hobbyists.
Part-1 was aimed at the casual / full-scale aircraft X-Plane pilots, who are not RC enthusiasts. It's purpose was to highlight that VSKYLABS RC-Elements (RCE) is not just another X-Plane aircraft add-on, and if one is not intentionally aims for RC flying, then RCE may not be your choice for his next add-on purchase for X-Plane, even if he loves the VSKYLABS full-scale add-on releases.
This Part-2 article does quite the opposite, aimed at RC pilots or enthusiasts, who most probably already have used an RC flight simulator at some point their your hobby.
In this article, I will explain what RC-Elements (RCE, in short) is from the perspective of experienced RC pilots, Giant-Scale RC pilots, and those preparing to make their first transition into Giant-Scale flying. I will compare it to traditional RC simulators, and why it may be extremely relevant for...you!
OK! Let's begin with the obvious question...
Is VSKYLABS RC-Elements considered an RC flight simulator?
Yes.
Although it is an add-on, RC-Elements transforms X-Plane 12 into a comprehensive RC flight simulator / flight simulation environment, combining advanced flight dynamics, weather simulation, global scenery, and a growing fleet of Giant-Scale RC aircraft (approximately above 2-2.5m wingspan). It is a dedicated RC flight simulation environment within X-Plane 12, designed specifically for radio-controlled aircraft operations.
At its core, RC-Elements is designed to simulate the operation of radio-controlled aircraft from the perspective of an RC pilot standing at the flight line. It supports a wide range of RC Transmitters and controllers, allowing comprehensive RC Pilot training and proficiency flying.
An RC Pilot who runs RCE on X-Plane 12, faces no-hassle experience; when running, it looks and feels like a dedicated stand-alone RC Flight simulator:
- You install X-Plane 12 and run it on your Win/Linux or Mac.
- You configure your TX controller in 1-3 minutes.
- You select your model and location from the GUI and initiate a flight.
- Aircraft is loaded, you are standing near it, and can change your position on the fly.
- You push the throttle, you fly.
...Why it is Build on X-Plane?
VSKYLABS RC-Elements is operating as a high-fidelity 'Study-Level' expansion layer built inside a full-scale aerospace simulation engine; X-Plane 12. By taking the advantage of X-Plane 12 cutting edge physics, weather and full-world simulation capabilities, RCE 'throws' its highly engineered RC models into the X-Plane 12 dynamic 'ocean'. This is huge, as I will explain later on, down this article.
X-Plane 12 dynamic 'ocean' is, of course, an analogy (although X-Plane does have plenty of actual oceans and detailed water-physics). I use this term to describe the vast simulation environment consisting of terrain, water-bodies, atmosphere, weather, physics, systems, scenery, and all the interactions between them.
Please bare with me, I know that using AI art has become lame these days, but I had to demonstrate the infusion of X-Plane and RC Simulation with the following illustration. X-Plane is vast, deep, dynamic and unpredictable sandbox:
Can we compare VSKYLABS RC-Elements to Traditional RC Flight Simulators like RealFlight or Aerofly RC?
Before I continue, it is worth noting that my perspective spans over decades of RC flying and RC simulation usage. Like many RC pilots of my generation (Gen-X mid-envelope), I learned the valuable (and expensive) lessons in orientation, RC model handling, aerobatics, and RC flight practices, back in the mid-late 80's through the 90s', way before RC flight simulators were available.
I have been actively using leading RC flight simulators since the early 2000s, gained countless of hours in RC simulators such as RealFlight, Aerofly RC, and earlier platforms such as FMS. My early days in RC simulation includes converting my old and decommissioned Futaba RC controllers into an RC Joystick for PC via the sound-card Joystick port...
The philosophy behind RC-Elements development is derived from decades of flying real-world RC aircraft, combined with countless hours spent in the leading RC flight simulators throughout the years.
There is a clear common threads that connects RC-Elements with other standalone, traditional RC flight simulators such as RealFlight and Aerofly RC, making a meaningful comparison possible: All are simulating RC model airplanes, all are built for RC enthusiasts and RC Pilots, from beginners to experts, and all are based on deep real-world experience in the hobby.
The following comparison is not intended to determine which simulator is 'better'. Each simulation platform was developed with slightly different objectives and serves different segments of the RC aviation community, with some overlapping.
The more relevant question is not which simulator is best, but rather what type of flying experience, training environment, and operational perspective each simulator is designed to provide.
Let's start with the basic Key Differentiators:
- Simulation Runtime: A fundamental distinction is that RC-Elements is an add-on for X-Plane 12, while all traditional RC flight simulators are standalone applications. As a result, RC-Elements benefits from the broader capabilities of the X-Plane platform while extending it into the field of Giant-Scale RC aviation. This also means that X-Plane 12 must be installed, as RC-Elements operates as an add-on rather than as a standalone application.
- Aerodynamic Simulation Complexity: While mainstream RC simulators focus on reproducing RC aircraft behavior through various dedicated RC flight dynamics models and methods, RC-Elements leverages a powerful real-world aerospace engineering simulation engine: X-Plane 12. It accurately models complex aerodynamics, propulsion systems like reciprocating engines, ducted-fans, jet turbines, turbo-shafts, counter-rotating props, and even rocket motors, all interacting with a fluid atmosphere in a wide-scale engineering sandbox. The entire flight envelope is simulated in real-time.
- The Atmospheric Factor: Mainstream RC simulators present mostly simplified atmospheric and wind models. Because RC-Elements runs inside X-Plane, the RC aircraft are subjected to air temperature and density factors, complex structural turbulence, real-world live weather tracking, turbulence, authentic low-level wind shear and many other atmospheric aspects. So it is not only how the atmosphere is simulating weather, but also (for example) how temperature gradient affects turbine or propeller thrust, engine power gradients and so forth. Your turbine model will behave differently when flown at -10°C compared to +40°C degrees, or at sea-level compared to high-elevated runways. Exploring the actual limits and capabilities of a given RC model in a comprehensive atmospheric environment is what X-Plane provides.
- The Operational Environment: Traditional RC simulators are typically centered around dedicated RC flying sites, whether rendered in 3D or based on photographic scenery. RC-Elements operates within X-Plane 12's full-scale, 1:1 representation of the world, allowing RC operations virtually anywhere (from ground level to space). Pilots may fly from conventional RC fields, grass strips, mountain ridges, frozen lakes, beaches, deserts, custom-built flying sites, or virtually any suitable location available within the simulation environment. This full-world approach not only expands the operational possibilities but also exposes the RC pilot to the environmental and geographical factors associated with a chosen flying location. For example, a confined air-strip, high-elevatet runway and so forth...
- Camera and Perspective Engineering: Mainstream RC simulators (mostly) rely on static ground camera pivots, usually a fixed position of the RC Pilot in a designated flying 'station', in the given (pre-set) RC airfield. However, RCE lives inside a comprehensive all-aspect flight simulation engine which is built for flexible views by default; external, chase, spot, in-cockpit, HUD, free cameras. All of these are allowing to set the RC pilot in the simulated environment literally in any position on the ground and in the air. Obviously, the base view system in RCE is the external, fixed spot view which provides ultimate flexibility. On top of that, RCE uses its custom G-REF ground-level dynamic camera system built to replicate exactly how an RC pilot tracks a high-speed vehicle from the pilot box without losing spatial orientation, in a more-dynamic-look-and-feel. This feature is mostly relevant when flying on 2-d displays.
- Target Audience: Traditional RC simulators such as RealFlight and Aerofly RC serve a broad spectrum of the RC community, from newcomers learning orientation and basic flight skills to experienced pilots practicing aerobatics and aircraft familiarization. RC-Elements shares common ground with traditional RC flight simulators while conducting a different approach, focusing on Giant-Scale operations across a diverse range of advanced aircraft categories, including turbine-powered jets, helicopters, experimental configurations, unconventional layouts, and advanced flight testing scenarios.
RC-Elements was designed to assist pilots in understanding the unique challenges associated with large and complex RC aircraft. Energy management, atmospheric effects, aircraft limitations, operational decision-making, and aircraft-specific handling characteristics become increasingly important as aircraft size, complexity, and investment value increase.
In this aspect, RC-Elements provides a safe environment in which pilots can gain experience in Giant-Scale RC flying, explore aircraft behavior, and build confidence before flying the real aircraft, helping to protect both equipment and investment.

About VSKYLABS Aerospace Simulations
RC-Elements is only one branch of VSKYLABS Aerospace Simulations.
Since 2015, VSKYLABS has been developing engineering-oriented flight simulation projects for X-Plane, ranging from historical aircraft and experimental concepts to real-world prototypes.
One example is the VSKYLABS Tensor 600X project, a simulation of the innovative Tensor 600X autogyro prototype that was developed alongside the actual aircraft during its early real-world prototype phase. As part of the VSKYLABS Test-Pilot series, the simulation evolved in parallel with the real aircraft program, providing a unique opportunity to evaluate and model a developing aircraft concept while it was still maturing in the real world.
This, and many similar real-world development experiences over the years, helped shape the engineering mindset that eventually led to RC-Elements.
The short video below demonstrates the Tensor 600X in X-Plane 12 environment:
A Personal Note
When I envisioned RC-Elements, my goal was never to replace or compete with the traditional RC flight simulators that accompanied me throughout decades of RC flying. In many aspects, traditional RC simulators remain excellent tools for orientation training, aerobatic practice, and everyday RC flying.
RC-Elements was developed to explore a different aspect of RC aviation. I wanted to explore what would happen if a highly engineered Giant-Scale RC aviation could take advantage of a full-scale aerospace simulation environment? Meaning, what if RC aircraft could interact with the same atmosphere, weather systems, terrain, and engineering framework used to simulate full-scale aviation? Obviously I knew the answer, since I've been doing this for quite a long time, on a limited & professional scope, using X-Plane.
For more than a decade VSKYLABS is involved in various real-world unmanned aerial vehicles prototyping and testing initiatives, within the aerospace industry. If X-Plane is being used, with great success, for prototyping and testing off-shore (just one example) fixed or rotor-wing UAV concepts and operations, why couldn't it shine for the RC Pilot who wishes to gain proficiency with a 19.5 feet, 4-turbine Vulcan RC model, or a 1:7 scale, twin turbine SR-71 RC model? or a 1:8 Scale XFY-1 Pogo RC model?...
RC-Elements became my first full-scope attempt to answer that question. The 1:5.8 scale A-10X in RCE Vol. 1 was the 1st in-house demonstrator in VSKYLABS RCE development journey. After a deep research and engineering process, it was carefully developed as a high-definition model in X-Plane 12. Test-flights have been a jaw-dropping experience, both in 2-d and VR environments. For me, it was a dream-come-true experience, as I was able to experience Giant-Scale 'monsters' like the 19.5 feet span Vulcan model, in a high fidelity simulation environment.
Various VSKYLABS RC buddies who participated in the development and testing process were occasionally left speechless. For me, as an experienced real-world pilot and RC pilot, the immersion of 'standing' beside the huge RC Vulcan model in a full-scale 1:1 world, in VR, on a 50-meter-wide runway on a rainy day, was unlike anything I had previously experienced in RC simulation...or in real-life!
VSKYLABS RC-Elements is not a replacement for traditional RC simulators. It is simply providing a different approach, focused on Giant-Scale operations, aircraft engineering, atmospheric interaction, and the unique challenges associated with complex RC aircraft, built to provide valuable, true-to-life training.
Whether RC-Elements becomes part of your RC flying journey or not, I hope this article helped clarify what it is, what it is not, and why it exists in the first place.
