VSKYLABS VSL 510X-VLJ INTRODUCTION
The VSKYLABS VSL-510X is a highly-defined Very Light Jet (VLJ) simulation, developed and engineered using the Cessna Citation Mustang (Model 510) as a core reference for a typical, modern VLJ aircraft. The main purpose of the VSL-510X add-on is to introduce the Very-Light-Jet aircraft category and to allow exploring its operational envelope in X-Plane Flight Simulator, stretching it to its out-of-the-box limits.
DEVELOPMENT DISCLAIMER: The VSKYLABS VSL-510X is an independent VSKYLABS development project which is not affiliated with, endorsed by, or connected to Cessna, Citation, or Textron Aviation Inc. It was not developed as an official rendition of the Citation Mustang, nor claimed to be so.
The VLJ Category
The term Very Light Jet (VLJ) describes a class of small business jets that typically seat four to eight people and are often certified for single-pilot operations.
These aircraft emerged with the goal of reducing operating costs and enabling jet access to smaller airports and shorter runways, essentially allowing more flexible, point-to-point business or personal travel.
The REAL-WORLD Cessna Citation Mustang
*The Mustang aircraft served as a core reference for a typical, modern VLJ aircraft, in the development of the VSKYLABS VSL 510X. Please note that the VSKYLBS VSL 510X-VLJ is not a direct replica of the Citation Mustang. Various differences in appearance and operations may be noticeable.
The Cessna Citation Mustang (Model 510) is a prime example of the VLJ concept: manufactured by Cessna Aircraft Company in the United States, it first flew on April 23, 2005, and entered service in 2006.
In its standard configuration it carries four passengers in the rear cabin, a toilet, and two-pilot/one-pilot certified cockpit seating.
Designed to bring jet performance into a more accessible segment, the Mustang offered the advantages of twin aft-mounted turbofans, a stand-up cabin, and the ability to be operated by a single pilot, features that made it attractive both for owner-pilots and small charter operations.
Although production ended in 2017 after 479 units were built, the Mustang remains a useful reference platform for high-fidelity simulation and systems-logic modelling.
VSKYLABS VSL 510X-VLJ MAIN FEATURES:
Highly-Defined Very Light Jet (VLJ) simulation:

Highly Defined Flight Dynamics, tested by real-world high-performance Jet Aircraft pilots.
Comprehensive systems:
Systems architecture derived from the Model-510 VLJ.
Powerplants & FADEC, pressurization, lighting, landing-gears, flight controls, fuel system, fire protection, electrical, ice and rain protection, master warning system, oxygen and more.
Comprehensive Avionics:
LR X1000 3-screens layout: Pilot, Copilot, MFD.
GFC 710 AFCS Control Unit-type
GCU 476 (479 pop-out).
Fully featured, comprehensive autopilot.
Plausible, comprehensive MFD-EICAS display based on X-Plane LR X1000 with customized MFD/CAS (Crew Alert System), allows operational following Model-510 procedures within reasonable margins.
Two aircraft included:
VSL 510X-VLJ'Production aircraft': derived from a pure Mustang-Class VLJ reference.
VSL 510X-ER 'Prototype aircraft': extended range variant equipped with two 400 lbs wing-tip fuel tanks, hybrid cockpit configuration, experimental equipment.
Fully compatible with X-Plane 12 native Ground Handling features (GPU, Chocks, other services).
Full VR compatibility (optimized for 2-d).
Comprehensive FMOD sounds.
Built-In Avitab compatibility (avitab plugin not included).
VSKYLABS 'Cockpit-Builders Heaven': Allows assigning all aircraft switches, knobs, levers, and interactions in a designated, uncluttered section in the X-Plane 12 assignment screen (see sample in image below).
VSKYLABS 'Gesture Gate' Throttle Cutoff mechanism: The 510X features a simulated cut-off detent that replicates the mechanical gate of the real aircraft. The system detects a deliberate throttle movement pattern meaning that NO extra buttons or hardware assignments are required.

Update Log VSKYLABS 'Test-Pilot': 510X-VLJ JetManHuss - VSKYLABS (c) 2025 All Rights Reserved
XP12 - Version v1.0.4b (15th December 2025)
VSL 510X-ER variant: Bug fix (tip tanks transferring issues in cold and dark/after shutting down engine, on each side).
XP12 - Version v1.0.4a (10th December 2025)
Major Update Release - End of Early-Access phase:
All planned features and refinements which have been planned for v1.0 have been implemented. The project successfully entered the long-term development road-map!
Aircraft split (two separate variants included):
VSL 510X-VLJ'Production aircraft': now derives from a pure Mustang-Class reference.
All prototype/test features (hybrid cockpit, experimental pitot system) have been removed from this variant to provide authentic VLJ simulation.
VSL 510X-ER 'Prototype aircraft': extended range variant equipped with two 400 lbs wing-tip fuel tanks, hybrid cockpit configuration, experimental equipment.
Interaction:
GCU Keyboard interaction cursor changed to 'Button type'.
GCU Keyboard pop-up interaction zone added to allow pop-up of the keyboard with direct interaction (mouse/VR).
Rotary Test knob is now wrapped-cyclic, allowing full cycle over and over.
Systems:
Systems architecture refinements to fall in line even closer with the Mustang systems reference for v1.0 release point.
Ignition system enhancements to fall in line with the Mustang auto-ignition internal workflow.
Fuel system enhancements, boost-pumps are now energized during engine start sequence, for each engine.
Engine-Fire lights (push buttons), added generator trip, and now allows resetting generators trip, fuel isolation and extinguish bottle arm, when depressed.
Built-In Avitab Integration:
Avitab (freeware plugin, not included) can be set and removed on the pilot's yoke (stowed in the aviation bag next to the copilot seat).
FMOD Sounds:
Overall refinements and mastering.
Paint-Kit:
Paint-Kit v1.0 was added (GIMP format).
Bug-fixes (v1.0.4a):
STBY altimeter now reads stby alt correctly, manipulator-not functioning bug was fixed, typo on the altimeter plate was fixed.
XP12 - Version v1.0.3 (5th December 2025)
Ground ops envelope added:
Aircraft is fully compatible with X-Plane 12 native Ground Services, including GPU (Ground Power Unit) and other ground services.
GPU state turns on automatically when the GPU receptacle door is opened, once the service arrives to the aircraft.
Auto-chocks are installed in cold and dark start.
Windshield sun-visors are placed in cold and dark.
Interaction:
Pilot's head is now hidden ONLY when the internal position of the camera is very close to the head - to prevent seeing headless pilot in internal views even when the camera is positioned further away.
Chocks interaction can be executed with the mouse/VR on external view, with dedicated interaction zones positioned on the tires. (This interaction comes in parallel to X-Plane 12 Ground Handling window interaction).
Windshield sun-visors added: Interact with them (mouse/touch/command) to remove, interact with the windshield sticker, placed up in the center-corner of each windshield piece, to install.
FMOD Soundpack enhancements:
Added in-flight ambient sound with slight ear-pressure effect during flight.
Throttle 'blip' throw was reduced by 50% to allow smoother and easier 'blip' range especially in axial throttle hardware.
Added dedicated commands for cutoff/idle and toggle. The commands are accessible via the VSKYLABS Assignment Layer (via X-Plane 12 assignment system), and can be interacted via lua as well.
