Schlowy, the more I play this game, and the more I learn about aerodynamics, the more I realize that HTC has done an absolutely great job using a vector flight model to represent the Fluid Dynamics that in the real world, make an airplane fly. There are bugs out there perhaps, but most, I believe, are problems with solid, indisputable documentation with respect to the actual aircraft performance, structure, and testing.
There are very good aerodynamic reasons why the 109 loses elevator effectiveness at high speeds, even before compressibility becomes a factor. Those same aerodynaic factors are why other planes don't lose elevator effectiveness at high speeds.
If you are receptive to an explanation, I'll post one. If you continue to think there's some sort of Allied superiority agenda in this game, I'm not going to bother.
