A2A has recently announced that they are offering their warbird P-40 with Accusim for free, in an effort to support the community during this difficult period.
You just need to log on to their store (you need an account, you can create one for free of course) and "buy" the P40 for 0 dollars, if I understood correctly.
For those who don't know what Accusim aircrafts are about, they are simply the definition of "high quality" or "realistic" addons.
Accusim brings in some unique features that make the aircraft alive.
The simulation of the engine behavior and the various mechanical and electrical systems/organs is way beyond any other addon makers.
Accusim is able to simulate many things that the simulator itself isn't. If you never owned any Accusim aircraft, now is your chance to understand what many of us have been bragging about for all these years
Of course now the A2A servers seem to suffer a bit from this announcement, so you may have to use a lot of patience
