XP11 - v3.7 (20th November 2017):
- This update was triggered to encounter some engine issues which were detected inX-Plane 11.10 beta versions. It is a minor update in terms of features, but a majorupdate in terms of internal engineering and preparation for the upcoming updates.
- X-Plane 11.10 "ready":
- Fixes to engine's simulation model for X-Plane 11.10 compatibility.

- 2D view with HUD is showing now only the HUD.
- Cockpit object camera movement restrictions - now you can't move through the wallsand panel.
XP11/10 - v3.5 (20th April 2017):
- MAJOR UPDATE RELEASE - New (3rd) aircraftincluded:
- Bush Plane version of the EuroFOX A220 aircraft, equipped with Tundratires.
- Flaps and Drag are slightly modified, as expected in real life STOL aircraftmodifications. It is more close to a "bush-plane"in terms of short takeoffsand landings capabilities, but it is still a "EuroFOX"(challenging to land onthe spot because of its flaps design).
- The Tundra-tires version is located in the A220 folder of the package. Boththe A220/Standard and A220/Tundra are located in the same folder.
- Performance fine-tuning for the A240/A220 models (drag and flaps handling).
- Separate Icons for each aircraft (for the X-Plane 10.51 versions).
XP11/10 - v3.4 (8th April 2017):
- Flight dynamics model fixes and tuning:
- Engine simulation - *Internal* flight model fix to rotation settings.
- Braking power *reduced* - to allow more authority when braking (especiallyin the A220 model). This tuning makes it easier to manage the brakes withouthaving a propeller strike while running. X-Plane has two levels of brakingcommand (when using/assigning a key/button to braking). For the higherspeed range, use the "Normal" braking assignment, and when really slow orstanding still for engine run-up or in an emergency, use the "Maximumbraking effort".
- These are X-Plane's default keys for braking:
- 'b' = normal brake.
- 'v' = maximum braking effort.
XP11/10 - v3.3 (8th April 2017):
- Minor fix to the Fuel Gauges display mechanism.
XP11/10 - v3.2 (5th March 2017):
- This is a Flight Dynamics fine tuneup release. Current version is:
- EuroFOX A240: v003.2
- EuroFOX A220: v003.2
- Flight Dynamic Modeltuneup (both models):
- Sink rate is a bit steeper with full flaps, which allows now a more slower andsteeper finals to get this little fellow to land on the spot, more comfortably.
- Performance fine tuning: the aircraft should feel a tiny bit more "lazy",especially in the roll axis, for more realistic handling characteristics.
- Pitch Trim is a bit slower in response, will allow to fine-tune the pitch trimduring cruise more comfortably.
- 3D model:
- Minor 3D model texture fix for both models.
XP11/10 - v3.1a (2th March 2017):
- This is a minor-fix release (textures and 3D model fixes to the EuroFOX A220 model). Current version is:
- EuroFOX A240: v003.1a (same version as the last one).
- EuroFOX A220: v003.1afix (minor fixes to textures and 3D model).
XP11/10 - v3.1a (1th March 2017):
- Additional aircraftincluded:
- The tail wheel A220 aircraft was added.
- Flight dynamics model tuneup:
- Cruise speed tune-up - now slightly higher in both models.
- Total performance of the EuroFOX is now tuned to its final phase; long runfine tuning may proceed in future versions.
- Pilot functionality:
- Due to requests for fixing a Kilometers Per Hour (km/h) airspeed gauge, I'veset up both the A240 and the A220 with a switchable Air Speed Indicator. Totoggle between mph and kph, just click on the Air Speed Indicator edges.
XP11/10 - v3.1 (26th Feb 2017):
- This is a Major Update Release, and the last pre-planned one to the flight dynamicsmodel, as it reached to its final phase.
- Flight dynamics modeltuneup - final phase:
- Rotax 912 engine and propeller simulation overhauled: Idle, Max static RPM,RPM changes due to airspeed, engine behavior when cut-off, reductiongearbox working very good now.
- Total performance of the EuroFOX is now tuned to its final phase; aircrafthandling characteristics is now solid in all flight regimes.
- Systems:
- Fuel, stater, choke systems tuneup.
- 3D Modeling additions:
- Wing fuel tanks Fuel caps (above both wings).
- Pitot tube (under the right wing).
- Mass balances for the flaps (tubes that are sticking out in front of each flap).
XP11/10 - v3.0 (20th Feb 2017):
- Flight dynamics modeltuneup:
- Important note: The VSKYLABS EuroFOX is now setup with a higherdefinition flight dynamics model. Many aspects were deeply analysed andmodified. This phase (v003) is "experimental" right now, as flight testingproceed. If everything will prove to be solid and stable, it will be the "mature"flight dynamics model of the Tricycle EuroFOX.
- Flare technique of keeping the nose high, without extreme pitch trim up, andtouchdown at approximately 45 mph (with the nose slightly up) is nowpossible. It is still recommended to get stable in a final with a trimmedaircraft as a preparation for landing.
- Stall characteristics of the aircraft might become more violent, ifexecuted/occurred in extreme maneuvering. The aircraft is now less safethan the one in the previous versions, and like the real thing, you have towatch out from tight maneuvers when flying slow and un-coordinated.
- Electrical System:
- X-Plane 11 version: Electrical system is now fixed, Battery/Magneto power isnow working as it should be (X-Plane 11 has a slightly different electricsystem core from that of X-Plane 10).
- Flaps and Trim are not electric (!) and can be operated with dead Battery andengine.
- Pilot functionality:
- Throttle operation: The throttle can now be operated with the mouse; pressand hold the mouse button while on the throttle lever and set the mouseforward and backwards to adjust power.
- Flaps operation: The Flaps can now be operated with the mouse; press andhold the mouse button while on the Flaps lever. If you "throw it" up or down,the flaps will go all the way to it's limits (up/maximum down). You don't haveto wait, just"throw"it up/down). For fine and gradual operation of the flaps,press and hold the mouse button, and slowly move it up or down, to set it in adesired position.
- Cockpit environment:
- Radio, IFF panels and buttons are now having a photo-real, high resolutiontextures.
XP11/10 - v2.0 (20th Feb 2017):
- Flight dynamics modeltuneup:
- 'Stuck on unpaved terrain' fixed.
- Engine static RPM now exceeds ~4,900-5,000 RPM.
- Propeller and engine models tuned one step forward for accurateperformance at a wider flying speed range (from static to high-speed flight).
- CG, drag and controls fine tuned for more docile low-speed behavior (don'tforget to operate the pitch trim during flight).
- Cockpit environment:
- A new set of high resolution 3D flight instrument gauges wereimplemented. New high resolution 3D Altimeter gauge with easy to setbarometer setting knob (click-and-drag).
- Flight instrument gauges glass 'dirt effect' was changed to a more clearer,reflective glass. The GPS flat screen is still dirty as an artistic choice ;)
- Garmin 530 GPS textures replaced to a photo-real textures.
- GPS operation LED indicator was implemented into the GPS (use the Avionicswitch to turn on/off).
- Front panel set to high-resolution textures, with crisp cockpit placards.
- 3D modeling:
- Interior cabin textures fine tuned all around the cabin.
