Installation

Install by merging the GameData folder in the zip with the GameData folder in your KSP install

ModuleManager and ModularFlightIntegrator are REQUIRED for FAR to work properly. Failing to copy this over will result in strange errors.

Legacy wing configs

Sample Part.cfg:

For wings

MODULE  
{  
    name = FARControllableSurface / FARWingAerodynamicModel  
    b_2 = 0.5                       // distance from wing root to tip; semi-span  
    MAC = 0.5                       // Mean Aerodynamic Chord  
    nonSideAttach = 0               // 0 for canard-like / normal wing pieces, 1 for ctrlsurfaces attached to the back of other wing parts  
    TaperRatio = 0.7                // Ratio of tip chord to root chord generally < 1, must be > 0  
    MidChordSweep = 25              // Sweep angle in degrees; measured down the center of the span / midchord position  
    maxdeflect = 15                 // Default maximum deflection value; only used by FARControlableSurface  
    controlSurfacePivot = 1, 0, 0;  // Local vector that obj_ctrlSrf pivots about; defaults to 1, 0, 0 (right)  
    ctrlSurfFrac = 0.2              // Value from 0-1, percentage of the part that is a flap; only used by FARControlableSurface  
}

For control surfaces, use above but replace FARWingAerodynamicModel with FARControllableSurface and add maxdeflect value

Set all the other winglet/control surface values to zero

Control surfaces can now be set to deflect in response to local AoA changes
Control surfaces are not On/Off for a given control direction; can be scaled from -100% to 100% for each

Contributed by Bitronic:
Full Tweakscale Support

BugFixes:
Fixed no shielding with some payload fairings (particularly resized procedural fairings)
Fixed aero tinting blocking tinting from other mods

0.14.3.2v------------------------------------
Features:
Contributed by Da Michel:
Airspeed settings change readouts in cockpits

Bugfixes:
Fixed serious issues with the wing interaction code
Fixed an issue where wind velocity was applied in the opposite direction that was expected

0.14.3.1v------------------------------------
Features:
Improved performance in editor and flight for vessel configuration changes
Fliht GUI appears in mapview

Bugfixes:
Fixed neverending stall resulting from wing interactions with sudden changes in velocity vector direction
Fixed flight GUI issues when passing another vehicle

0.14.3v------------------------------------ Features: Refactored wing interaction code:
Wing interactions should be smoother
Code should be less processor intensive

Upgrade to ModuleManager v2.5.1
Added stall visualization to aero force visualization
Added ability to scale wing mass up or down for additional strength / weight savings (addedby NathanKell)
Improved cargo bay and payload fairing detection algorithm

Tweaks:
Reduced intake drag
Decreased wing mass per area slightly

Bugfixes: Fixed aero visualization leaving parachutes glowing brightly
Fixed some critical errors for when config files do not have values listed
Fixed an issue with AppLauncher buttons multiplying when KSP fails at loading a particular vessel

0.14.2v------------------------------------ Features: 0.25 compatibility, with stock support for SP+ parts
Upgrade CompatibilityChecker
Disable functions on CompatibilityChecker warnings

Prototype aero force visualization in flight
Removed vector from CoL indicator to reduce confusion
More Get functions for the FARAPI
Estimated range and endurance readouts in the Flight Data UI
See and dump FAR module data in the VAB / SPH using the Editor GUI
Some runtime optimizations

Contributed by Da Michel:
Implement separate deflection speeds for flaps / spoilers
Allow preferred default action groups for spoilers / flaps
Contributed by regex:
Add some RPM integration
Contributed by Ippo:
FARWind class for 3rd-party wind implementation

Bugfixes: Fixed some vessel-switching FAR GUI issues
Fixed control surface reversal on undocking or backwards root part selection
Fixed some issues involving CoL position with wings when dealing with parts that have multiple colliders
Fixed some payload fairing and cargo bay part detection issues
