VSKYLABS 'Scratch Built RC Legends' project

VSKYLABS 'Scratch-Built RC Legends' 2015
Project introduction:
A complete Radio Controlled simulation pack for X-Plane 10.
This project is aimed to be a professional and a best choice RC simulation.
(Linux/Mac/Windows compatible)

If you own (or would like to own), or build (or would like to build) a Giant-Scale RC model, and would be interested in real, professional simulation for actual training of such platforms, you might be interested in the VSKYLABS 'Scratch-Built RC Legends', and what it has to offer. 

This add-on is not designed nor intended to be a PC-Game, but the most advanced RC Flight simulation on PC.

Not familiar with X-Plane flight simulator?
Read the Green information below.

What is X-Plane?:
X-Plane is a flight simulator created by Austin Meyer and produced by Laminar Research. Besides being packaged with several commercial, military, and other full-scale aircraft models, it includes a basic global scenery which covers most of the Earth. X-Plane also includes software to build and customize aircraft and scenery, letting users to create their own scenery or replicas of places on Earth, and/or any flying design they thing of (replicas of real-life airplanes, or experimental, self-designed vehicles).

The most recent version is X-Plane 10.36 (28.05.2015). X-Plane 10 comes in eight dual-layer DVDs, including the world global scenery (86 GB compressed). The scenery spans from 70 degrees south to 74 degrees north. 

X-Plane is not a game, but an engineering tool that can be used to predict the flying qualities of fixed- and rotary-wing aircraft with incredible accuracy. Because of that, X-Plane is a great tool for pilots to keep up their currency in a simulator that flies like the real plane, for engineers to predict how a new airplane will fly, and for aviation enthusiasts to explore the world of aircraft flight dynamics.

X-Plane's Flight Model explained:
X-Plane is different from most simulators by implementing an aerodynamic model called 'Blade Element Theory'. Traditionally, flight simulators simulate the real-world performance of an aircraft by using predefined empirical data (which was gathered by the use of wind tunnels or test flights), to determine aerodynamic forces such as lift or drag during known flight conditions. These simulators sufficiently simulate the flight characteristics of an aircraft with known aerodynamic data, but are not very useful in the design process, and can't predict a performance of an aircraft in case that the actual data is not available.

Blade-element theory is often used to compute aerodynamic forces of a new design.
With Blade Element Theory, a surface is divided into several sections, and each section is further divided into separate subsections. The lift and drag of each section are calculated, and the resulting effect is applied to the whole aircraft. When this process is applied to each component of the aircraft, the simulated aircraft will fly similar to its real-life counterpart, especially on the physical aspect. 

X-Plane can model complex aircraft designs, including helicopters, rockets, rotor craft, and tilt-rotor craft. Blade element theory is far from being perfect, and there are lot's of aerodynamic aspects which are not included in it's calculations, but as the flight model is refined, the simulator can give a rather close experience and/or conception of real-world performance, and also "discover" various design flaws.

Read more about X-Plane at it's official website:


'Scratch Built RC Legends' flying Airfield - 'RC-CITY':
The project involves an interactive ('everything you see can damage your plane') R/C airfield, equipped with take-off ramps, pylon poles, obstacles etc. View point of the R/C pilot is set-up to the right spot, ready for action.

The flying field is perfectly tailored to R/C operations and training.
The objects in the environment are physically existing, so the airplane can collide and interact with them (antenna's, cars, ski-jump ramps, pylons, fences etc.).
The objects are also arranged carefully in the flying area so it may give the R/C pilot clues about depth perception for training, since there is no real depth perception in simple 2D monitors. Pilot position is well thought of and placed at the right spot and elevation.

Model Airplanes in the package:
The package contains detailed and amazing 'giant scale' R/C model airplanes such as
the D.H.88 Comet, the P-38, the Grumman SkyRocket and more. Some models are 'FPV' ready, which means that you can fly them as real FPV models.

When and how does the package will be available for download?
The package is on it's final phase of development, and it is most likely that it will be ready somewhere around mid-August 2015.
The 2015 package will include at least 6 highly detailed and professionally tuned Giant-Scale R/C Model airplanes, and the interactive R/C flying airfield.
The package is aimed to be an affordable, high value Payware.

Flight performance of the models is the most important part of the concept, and it is simply AMAZING.

VSKYLABS review UL-104

VSKYLABS UL-104 Ultralight Bush Plane review by 'Edwardhearing'

This review was written back in 2012, by one of the users who downloaded and enjoyed the VSKYLABS UL-104, and posted it in the website. I've just "found" it again, and asked his permission to upload it here in my Blog-Website. 

Thank you Edward for your time and writing.

You can find this airplane and download it in the 'JetManHuss Original Prototype' section.


The VSKYLABS UL-104 Ultralight Bush Plane
Review by 'Edwardhearing':

After two weeks of flying this concept ultralight, I feel confident to write a short review, since it's a very interesting project. This is the first time I write a review, so I hope it will serve others than me...

I will divide my review to several subjects: General concept approach, 3D modelling and graphics, flying qualities and conclusion:

General concept approach:
Flying simulator models is all about igniting your imagination. If a model is making your imagination working, you will start "playing" the role of piloting it, and a wave of satisfaction will flush your mind! examples: flying space vehicles, flying re-entries to earth, flying a jet fighter etc. We are "playing" the role and have a chance of being in the situation. Sometimes a really detailed cockpit and sounds can help us enter the role. When I first saw the screenshots of the UL-104 (the first person ones), something worked for me. The concept of a "plausible home-built machine", as it's described at the vskylabs website, made me curious and "ignited" my imagination.

Knowing one or two things about aviation, aerodynamics and home-built ultralights, I read the description of the concept. It is straight forward ,making sense and in correct approach for it's purpose. In that matter, it reminded me the analysis of the Thunderbirds FireFlash plausability in the real world at It seems like there is a good and correct knowledge base and for me, it's a kind of "ensurance" for a good flying model design behind it's looks.

For conceptual approach I score this model 9 out of 10. Why 9? Because it is almost perfect. Additional version of the plane, for example a sea-plane version with floats, is needed for filling an imagination gap in my mind...

3D model and graphics: 
The 3D model of the aircraft is complete: Fully animated, with a fair amount of details. There is an inner structure that is "hiding" underneath the fuselage, with animated push/pull lines for nose wheel steering and controls. The structure is simple "aluminum" poles, but they are arranged in a logic manner, giving a good feel of 3D environment inside the cockpit. Texturs are simple but yet in a high resolution and they are covering the plane in a good harmony. The canopy is textured with some transparent mud tracks that gives a good feeling of "being there", especially when the sun is low. Cockpit is simple, functional and sure looks plausible. Using an iPhone for an artificial horizon is brilliant, and helped me "playing the role" of an amateur ultralight pilot, fighting the weather...

Exterior graphics is good, doing the job of representing the model, with high textured "jungle" or "bush" camo. The camo textures are giving the model the looks of a "well used bushplane", adding meaning to the imagination stuff mentioned before.

For 3D modelling I score this airplane 7 out of 10. Why 7? First of all, I guess authors are not a big commercial company. I hope I'm getting this right, but their approach seems to me like an enthusiastic approach rather than business, which means that like in the home-built-airplanes-people-community, there is always lack of resources, but that's what makes you using them smartly. Overall, the modelling is really effective giving you the idea of "being there".

Flying qualities:
The UL-104 is a "dune-jeep" that looks like an airplane! the power/throttle feel is really good, especially for pilots who are used to fly real low-power fixed pitch ultralights; The response of power is fast, but as soon as you reach cruise speed...that's it... I ran this plane my "landing test": landing "on the spot", on a restricted area that requires a steep final. In real life, small ultralight planes need a high RPM almost in any stage of the flight, including landings. The management of the potential in the UL-104 is almost perfect!!! The drag to power and lift feel is as real as it can be. For me, it helps playing my role of being there, landing it in a deserted troublesome airfields...

For flying qualities I score this airplane 8/10. Why 8? because 10 cannot be achieved in a simulator...not at the present, and it did passed with an A+ my landing test. It could use a more larger rudder surface for easier single engine operation.

The UL-104 is a cool, refreshing, "practical" package that combines realism, fun and flexibility of use, for hours over hours of fun. The plane successfully gives you the idea of pilotting an ultralight plane. Overall the graphics are good, engine sound is great and well sampled. This project is well defined and executed. This add-on will not stay parked in your hangar even after months of use.

This package is scored 8/10. In my opinion, the value of a plane is not only related to the number of switches animated in it's cockpit. This is a lesson I learned after using this well-done package.

Hope you'll find this useful:)

VSKYLABS 'Scratch-Built RC Legends' RC Setup Panel

VSKYLABS 'Scratch-Built RC Legends' 2015 New RC panel introduction (26.5.15)

One of the most important goals of the 'Scratch-Built RC Legends' 2015 project is to make the RC simulation in X-Plane more accessible for RC pilots who are used to fly the designated commercial RC simulations nowadays.

Take a look at this video, demonstrating the easy access for X-Plane setup features, allowing you to setup the simulation easily for best RC simulation training. The setup is also functional in-flight and changes could be made during flight, without the need to pause the sim, or to deal with X-Plane's various setup windows.

This panel is not complete and additional changes could be implemented until the final package is ready.

Easy Handling & Orientation Training feature

VSKYLABS 'Scratch-Built RC Legends' 2015 news (20.5.2015):

This is a brief 'News' update, revealing some more features of my 'Scratch-Built RC Legends' 2015 project for X-Plane 10 flight simulator.

* Having the development running even faster than planned, release of the VSKYLABS 'Scratch-Built RC Legends' 2015 is expected to be around mid August 2015.

The 'Easy Handling and Orientation Training' Feature:
One of the most thrilling features I've implemented in my 'Scratch-Built RC Legends' RC models is aimed for beginners. A known and frustrating matter for a beginner RC pilot is that once he or she hits the throttle, their flying, living RC model's 'Event Log' is growing rapidly, and each second that pass makes the spatial situation and conception more complex, mainly due the very low orientation and handling skills. 

What I've decided, is to give the pilot a choice of 'Freezing' the model, up in the air, at a desired point, while all the physics is still running. The model will fly but will not lose height nor change it's position. It is possible to select a desired point of view, and start practicing orientation, especially when the model flies inbound (pointing at the pilot). 

Because the physics is still running, it is possible to practice some handling aspects as stalls, spins, single engine operation and more.

Once decided, the model can be 'released' and set free to the skies! (see video below).

Until next time :)


Here is a video, demonstrating the 'Easy Handling and Orientation Training' feature:

In addition, Here is a short video showing some cuts from the (long) process of tuning the 'Fun-Factor' of the package :)

VSKYLABS 'Scratch Built RC Legends' Development Report 30.04.2015

VSKYLABS 'Scratch Built RC Legends' Development Report 30.04.2015

Crosswind handling demonstration
Here is a new short video showing handling trials of some of the models within the package, this time dealing with cross-wind performance evaluation.

X-Plane's physics is amazing, showing a very realistic model airplane behavior, especially when simulating larger-scale models. One of the Key design aspects in my RC model airplanes for X-Plane is it's Drag/Thrust and Drag/Weight ratio. It's a long and demanding process for each model, but as the numbers are getting right throughout the process, suddenly, the model "comes to life". This is a great moment, when it actually feels like flying...

VSKYLABS RC F40&Countach

VSKYLABS RC Ferrari F40 and Lamborghini Countach LP500

General information:
This is an advanced R/C modelling of the Ferrari F40 and the Lamborghini Countach LP500. Car size is scaled down to 40%, making this a large RC type vehicle (both in size and weight). This project began as an experiment, and ended as an addictive toy!

Both models are simulated with a Four-Wheel-Drive physics, which allow the models to be controlled at over-steering or 'Drifting'.  Physical performance was stretched to it's limits with X-Plane, to make these vehicles look and feel like real 'Drifters'.

How it's made?
Well, X-Plane doesn't have wheel-drive propulsion systems, so each one of the wheels is actually a Jet-thrust-engine (!), located at the contact point of the wheel and the ground (just like in an ordinary car - the traction points are the small contact areas of the wheels and the ground). Stabilization is made by lift surfaces (!), which are invisible, and their job is to push the car into the ground while moving fast, or while power is applied.

Wheel friction coefficients are set up with high values. This is mainly for matching a smaller-sized wheel friction to real life behavior, and also for easy braking: idle the throttle and the car behaves as if you are using the brakes.

Here are some things you'll have to consider when using these vehicles in X-Plane:

  • I recommend using an RC type Joystick controller for quick and accurate control inputs (It's a scaled-down car so it moves fast, quicker response than in a full-scale car is needed). 
  • Use External views for Ultra-Fun experience :).
  • Wheel-friction is different on different surfaces in X-Plane, much more than you might expect. I recommend you to try different surfaces and choose your favorite.
  • The cars are tuned up for best realistic performance on asphalt or concrete surfaces.
  • Over-steering (or 'Drifting') is an art. It's a balancing act and controlling it is done by small but rapid inputs of steering and power.
  • Remember that this is actually a Jet-powered car, so once your velocity vector is pointed up and you apply power, it will get airborne. When the car jumps of the ground, in any reason, throttle down and let it get back to the ground...

Have fun!
