Well, in the interest of trying to have accurate representations of the the aircraft's performance capabilities, why can't HTC post THEIR source material for examination. Then if the community agrees on the validity of the source, it won't matter if another source disagrees. We will have an accepted baseline source to work with. However, I've never seen any of this. (is there some?)
HTC runs a business, and they have competence (WB, FA, WWIIOL, boxed sims, etc). The information they use to model the planes is something they don't want to show in public ,because that same information could be used by a direct competitor in their own Flight models.
Also, even today, many of the charts and informations regarding WWII planes are still classified or "licensed" for use under NDA agreements. For instance, Oleg Maddox (the designer of Il2) must have an amazing ammount of information coming from the russian data of late and post WWII tests....yet he can't show it in public because NDA agreements AND (of course) the said reason: you have an information you don't want to share with your competitors.
So don't ask HTC to show their sources. They won't. And they'll do fine in not doing it

I know this isn't a TA152H thread, but by source material I've found the AH TA152H runs over 30 mph slower than its published topend speed. See the subject under playability issues. Plenty of charts etc. (shrug) Haven't heard any response from HTC yet.
LOL don't get Wilbus started on this...again

. Yeah ,I agree, Ta152H is slower than what it should be at very high altitudes. this was already pointed and (IMO) demonstrated some time ago. I guess is in the fixlist too (but I also guess its very low in that fixlist...the Ta152 is a very low used plane anyway, and not many people go up to 35K, where the speed loss is

)
