Well in addition to the Albatros D.Va and Nieuport 28 C1, there are other WW1 FM's that come to mind as well: For example the S.E.5a seems to be underperforming in turns.

 

Thank you Holtzy. I was beginning to think she was the elephant in the room. But not just turns, general energy retention is poor. Perhaps @Gavrick could comment?

Another thing that could be good to discuss is the turn performance at higher altitudes, which I think in general is a bit on the optimistic side in flying Circus for all planes. Anyway, it's getting late here so I will call it a day for now, but good to hear from you and if you have any questions about the modeling, references or other things in my book then please feel free to post these here or in the PM thread we have with Daniil and Victor where we could also establish contact via e-mail.

Your model is interesting.

Does this model help you find stick forces at certain speeds
Calculate comprehensibility of the controls?
Discover if planes have tendencies to wing tip stall in aggressive maneuvers?
Or even on modern aircraft assess mach tuck?

No, stick forces and handling aspects such as a vicious or benign stall is not modeled. My model only looks at things like speed, acceleration, climb, turn, dive and zoom performance.

 

But I think it helps here to look at this having Maslow's pyramid/staircase model in mind: You gradually work your way up to more refinements, and basic flight performance is one of the first steps. In addition, stick forces are a big can of worms and VERY difficult to model correctly and to find reliable data on. So in summary, the first baby step is to get basic flight performance right, and that's where we're at at the moment.

 

But for sure, my model includes compressibility effect as well. But you can safely disregard those for WW1 aircraft modeling (barring propellers). In fact, without blowing my horn, you can find posts from maybe ten years back or more where I present data on compressibility effects in my simulations at a time when none of the available flight sims had yet incorporated that in their WW2 aircraft modeling.
