IIRC, there was a lot of discussion in several IL2 forums regarding the innacuracy of the Ta-152C FM.

The problems mentioned were:

• 1) It was discovered, when analysing Oleg's FM data, that the wing area wasn't correct. Instead of a wing with an increase of 1.5 sqmm in regard to the FW190, it uses the FW190's wing area. The 3D model has the correct wing area increase, but this isn't taken in to consideration for the in-game FM calculations.
  
  This agravates it's energy bleed and lack of sustained turn at all speeds (specially medium to low speeds). Since the 3D model has the correct increased wing area, this makes it quite probable that someone in Oleg's crew forgot to make the FM correction before releasing the new plane.
  
  2) Regarding the aceleration factor for the DB603 engine. It seems too slow like it is the case for Oleg's BMW 801 and Pratt & Whitney R-2800 engines.
  
  IIRC, in the standard game, it is something like 0.4 for both of these compared with 0.7 for Merlin. Which is very strange if we take in to consideration that both had very good acceleration and throttle response (specially the BMW 801).
  
  IMHO, although being unable to check the FM data, the acceleration factor or the kommandogerat for the DB603 must be off.
  
  3) Some people mentioned the weight was off in regard to RL data. Since I have no access to the FM data I can't say how accurate this claim is.

In regard to versions, we seem to have the Ta-152C1 modelled in game. Maybe another interesting one would be the Ta-152C3 version with improved radio and a Mk103 instead of a Mk108 through the propeller hub.

This is why I would like to open a discussion regarding these matters. I would apreciate people's imput. Specially people with more info on these planes and/or people with access to the FM data for comparation.
