    • Model internal architecture refinements.
    • Normal maps and glass (canopy) are nicer and shines perfectly.
    • I've switched between the 'Default white' and the 'Red stripes' liveries. Nowthe default livery is 'Default white'.
  • GNS 530 minor fix:
    • 'CLR' switch is now clickable when operating from the 3D Garmin itself.
  • Flight Dynamics Model refinements:
    • Minor adjustment to overall drag of the Phoenix so it is slightly less "floaty"on landings. This specific performance aspect is still under evaluation andfurther updates are to be expected.

XP11 - v4.2 (25th May 2017):

  • GNS 530 is now 'clickable':
    • It can be operated with and without using the pop-up.
    • Frequency and page/chapter knobs has mouse manipulators so you canswitch frequencies with the use of the mouse wheel or click-and-drag. Theclick-zones layout is experimental, and will be tuned up soon.
    • COMM2 + transponder are also using mouse manipulators:
    • same as in the GNS 530 - layout is experimental and changes are to beexpected.
    • COMM2 is now COMM2 (this radio is redundant and will soon to bereplaced with other instrument/navigation aid).
    • Cockpit camera can't go through cockpit canopy/walls.
    • 2-D HUD view shows only HUD, without the cockpit.
    • Propeller disc is now volumetric (not seen from the side as a "thin paper", but withvolume).

XP11 - v4.1 (18th April 2017):

  • Flight model refinement: Minor engine (internal flight model) fix.

XP11 - v4.0 (4th April 2017):

  • This is a MAJOR UPDATE RELEASE.
  • The aircraftis now capable of switching between short and extended wingtips:
  • To switch between wingtips, just 'look' at one of the wingtips, from cockpit3D view, point the mouse on the wingtip region and click on it!
  • When changing from Extended to Short wingtips, the flight dynamics modelis changing as well (flight dynamics model and 3D model are biased, so it isswitching the wings practically between 36 and 49 feet span).

XP11 - v3.0 (2nd April 2017):

  • 3D Modeling - 'Interactive':
    • Wing-flex animation added.
  • Experimental feature added: Aircraft is vibrating when the engine is running(external and internal). This is an experimental feature that I'm testing inv003. It may be removed in future updates (according to users experiencefeedback).
  • 3D Modeling - Aircraft painting:
    • Default livery improved.
    • Added an 'all white' livery.
    • Canopy is now featuring a tinted coating.

XP11 - v2.1 (30th Marth 2017):

  • Flight Dynamics - aircraft ground behavior Phase#1 tuning (cross-winds) - this aspect isscheduled for a Phase#2 tuning in the near future.
  • Propeller disc update (visuals).
  • Added Yaw-String...I've taped it with a silver Duct-Tape ;)
  • Modeling:
    • Emergency Feather lever angle when activated is set to a new value.
    • Minor 3D model fixes.

XP11 - v2.0 (27th March 2017):
