I dont know about that. This one says their model is correct, and that one over there says their model is correct. Whos to know for sure. I do know that every film I watch of DSC and it show's an exterior view the planes look like they are balanced on a needle at the COG. The planes dont so much roll, but pivot on a point under the belly at the COG point.
Ive never flown a real P51, but Hitech has and Im sure he did his best to get it as close as he could. Either way, spending hours flying around a DCS world LOOKING for a fight isnt my idea of fun. Even if their flight model was perfect to real life it still would get boring pretty darn quick.
From my POV... all the Warbids in DCS feel like they fall off their wings way too easy, except maybe the Spit (and the K4 isn't all that bad). The Pony is absolutely the worst. ~No~ other Flightsim produces this "feeling", at least not so glaringly. Eagle Dynamics states (paraphrased) that they go to great lengths to make the flight model as accurate as possible. I have no way of knowing one way or the other, but... the way the P-51 flies in DCS makes me wonder how it was successful at much of anything outside of going real fast real far in WWII. I did read an account of some Luftwaffe guy who said Spits worried them, but when they knew it was P-51s, they at least had a chance.
So, until some P-51/K4/D9/A8/Spit real pilots chime in regarding DCS, we're sorta stuck with what we've got for any given flight Sim. Now, I've heard a real life pilots for F-16s, F-18s & A-10s make these comments. The 16/18 guys said it was pretty dang close. The A-10 dude said the real plane was far more forgiving than the Sim one. And I think that's the crux of the problem here.... DCS is a Jet Sim, and they do it well. The WW2 part was, so I'm told, sort of a "failed start" they decided to stick with due to customer expectations (that's the short/easy way to put it). Regardless, all the flight models for all the sims work pretty great for where they are and what they do.
Oh, and looking for a flight isn't really hard in DCS these days,... well, Prime-Time. Both the highest populated WW2 servers have bases pretty close together. The Euro time frame might even be better than AH now (I don't know the current AH numbers).
