So I've made some good progress and have learned a lot about the physics model after experimenting with many settings. The ground handling in my opinion is pretty much as good as you could ask for and that was simply done by turning the tailwheel spring constant down. I increased adverse yaw by reducing the lift coefficient of the vertical stabilizer. This generally destabilizes the yaw axis which also feels a bit more real. Has the additional benefit of making the high speed landing and takeoff roll slightly more realistic. I also slightly reduced the lift coefficient of the rudder (flap) to balance with the decreased vertical stabilizer effectiveness. I increased propwashrotation slightly on the vertical stabilizer which gives a slight left turning tendency on the ground. However, nothing I have done is really giving a sustained yaw in the air. Even a fairly massive increase to propWashRotation will make ground handling uncontrollable but once in the air everything flies pretty much the same. Same goes for crosswind.
I also found this in the aerowing documentation:
"... P-Factor which can also be modeled with the AeroPropeller class using its
Would be curious as to who wrote this and if its accurate, if an example of modeling p-factor could be provided? I do not see a way to do it if I understand these settings correctly but hoping I am wrong ; )
Other things I am trying to figure out are: 1) getting prop speeds and airspeeds closer. 2) forward slip. 3) getting the bounce on landing slightly more realistic. If you touch down slightly on the main, the oscillation is too high a frequency. No questions on these latter parts yet as I haven't experimented enough.
RoyPettit I have done transition training into the Pitts but not anything other than basic aerobatics so don't want to comment on the knifeedge as it would be just speculation. That's why I have limited my Aerofly efforts to basic ground handling, adverse yaw, etc. Having said that, most of the low and slow knifeedges you see (Skip Stewart) are in planes that have much more horsepower and also not at 90 degrees as JetPack mentioned. Four point rolls at speed seem reasonable in Aerofly. But again, don't take my word for it!
