aelChordCoef10.0Aileron coefficient that amplifies the ael force. Used together with wingChord coefficient to simulate what proportion the aileron is to the wing chord wise. If chord wise wing to aileron is proportion 3:2, use wingChordCoef = 3n and aelChordCoef=2n where n=1,2,3.... experiment with n aelRate 100.0- used in easy setup to adjust aileron rate

dihedralRudCoef1.0Rudder to elevator coupling, makes plane leans when rudder applied
elevCoef4.0Lift coef for the elevator surface
elevCompCoef1.0Adds slight up trim so plane flies level, higher the more up trim it is (0 to 5-6)

gravity9.8Earth gravity, use 1.5 to fly on the moon.

landBounceCoef20.61Gear bounce coefficient when plane touches the ground above landSpeed speed 0<x<lt;x<x<lt;1
landSpeed6.0Used in simulation ground handling, use 8 for big planes 3-5 for very light and slow flying planes
landXCoef4.0Force used to simulate landing/ground crash, tricky to set, use form similar plane
landYCoef1.0Force used to simulate landing/ground crash, tricky to set, use form similar plane
landZCoef1.0Force used to simulate landing/ground crash, tricky to set, use form similar plane
liftConst3.0Const that resize all surface size. Plane with liftConst=4 has 2 times lower wing loading than plane with liftConst=2. Note that lower liftConst makes all flying surfaces less effective (ailerons, elevators etc) Use together with modelMass to get exact behavior. The modelMass will provide mass simulation behavior like model inertia at turns, liftConst defines how big the wing is. Note: wingDragCoef is related to liftConst. Use wingDragCoef= 1/2 from the liftConst, or be very careful and experiment with other values.
loadRealModel1.0Keep always to 1
maxAelerRate7.2Max rotation rate in radians per second that ailerons can induce. Note than 7.2 is 360 deg/sec, 14.2 is two rotation per seconds etc.

maxRotRate100.0Max rotation rate on Y in radians per second
maxScaleDist600.0After "maxScaleDist" meters, the program stops doubling plane in size.

maxTumbleRate100.0Max rotation rate on Z axis in radians per second
modelMass15.0Model mass in kg
modelNameEdge540-25.acThe ac file name with the model

wingCGCoef1.0Goes together with elevCoef. Higher elevCoef+lower wingCGCoef = Lower evelCoef + higherwingCGCoef for elevator agility. If you want the plane to snap fast when doing tail slides, go with Lower evelCoef + higherwingCGCoef, if you want plane to tail slide quite a bit, go with Higher elevCoef+lower wingCGCoef
