# Microsoft Flight Simulator / JMB Aircraft VL-3 915

This project is a realism and conversion mod turning the stock VL-3 912 into the versatile JMB Aircraft VL-3 915 top-of-the-line edition. This sporty composite plane is the fastest Ultra Light side-by-side in the world, able to sustain 370kph / 200kts cruise speeds at FL180 yet requiring only 180m / 590ft of runway.

*She's a sports car with wings, and yours to fly!*

## The Project

We are a team of like-minded enthusiasts that loved the VL-3 from the beginning and turned it into the best 915 we know how. In doing so we have made extensive modifications - always supported by factory data and pilot feedback - to the engine, propeller, flight model, various systems and flight controls.

### The Engine

We have upgraded the default Rotax 912 to the more powerful Rotax 915 iS engine. Fuel injected and turbo charged, it delivers a massive 141HP to an airframe that only weighs 600kg / 1322lbs at MTOW. A superb power to weight ratio that is guaranteed to turn the VL-3 into a pure joy machine!  

We have gone through great lengths to simulate every aspect of this powerplant, including oil temperatures, cooling temperatures, pressures, gearbox ratio, RPM ranges, critical altitude, compression ratio and a lot more.  

### The Propeller

The real VL-3 915 comes with an upgraded propeller, and so does ours. The 3 bladed constant speed and variable pitch 173.8cm / 5.7ft Woodcomp KW-31.  

While updating the actual 3D model is currently beyond our project scope (you will still see 2 blades), the KW-31's performance is simulated in excruciating detail.

### The Flight Model

Many hours have gone into creating the refined flight model as you experience it today. We have carefully analyzed factory data, observed videos, conducted hundreds of test flights and processed feedback from certified pilots (including a real test pilot) in order to give you the most authentic flight experience possible.

You can be assured that cruise speeds and climb rates (at all altitudes), taxiing, takeoff and landing behavior, clean and landing config stall speeds, roll rates, fuel consumption and so much more is closely or exactly matching POH (Pilot Operating Handbook) specifications.

### The Cockpit

Designed along with, and to use, the WorkingTitle G3X.  Please make sure to download the latest version from Working Title!

The speed steam gauge has been converted to knots in order to align with data presented in the G3X.

Due to popular demand, we have added a glareshield that can be activated for nighttime flying.  It can be used by mapping your controls for "glareshield" in the game options.

### The Liveries

Our project includes an ever-growing and diverse collection of liveries, contributed by various team members. Surely there is something to suit your taste!  
All our liveries are updated with authentic VL-3 915 performance placards inside the cockpit.
