Interesting post FOZ. Glad you tested the P-51's top speed at altitude to see if it matched the known speed. Nearly 100 MPH off? That's inexcusable.
It seems as if the P-51 has gotten the short end of the stick for some reason. One could argue that it appears to be intentional.
In case any developers are reading this can you respond? We know the patch has been submitted to Microsoft and it's not your responsibility but please keep us updated on any other updates. I've noticed you've been quiet for quite some time and I don't see any communication from you here or on the other forum (yuplay). Thanks!
