Yes in an attempt to fix this issue. Issue noted before adding physics fixes. Issue remains after adding as well.
Are you using Developer Mode or made changes in it?
No
Brief description of the issue:
P-Factor is backwards, not seeing gyroscopics, torque, loaded wheel / surface drag variations, rotational inertia, coupling length, with CoG affects on point of no returns for ground loops seem wrong as well. Not seeing slipstream delay to effect of controls for rudder and elevator, this could also be backwards along with the P-Factor. Tali wheel variations, steerable, free castering etc. not tested. (Does anyone know of an aircraft in FS2020 that uses both?)
This occurs on every take off, landing and taxi.
Known good working example:
Ground handling physics of free T51 Mustang in DSC World. Try flapless take off with tail wheel unlocked for good example of above effects, including suspension and inertia dampened center line tracking effects that calls for / allows realistic lively dancing on the rudder pedals to keep straight initially including gradual increases of the stabilizing effect of the vertical.
