With all due respect ... I'm highly suspect of "incorrect FDE" claims.
They had as part of their dev team Lt (N) Phineas Henshaw and Lt. Colonel "Stork" Reinhart doing the FDE for a number of years, certainly the period straddling the aircraft (FSX T-2 and A-7 family) in question ...
As to the A-7s - when landing with PROPER MGLW, trim, attitude, etc - I find them an absolute joy. Predictable, steady, and straightforward. They way folks are talking about fuel suggests that proper landing weights and general procedures aren't being followed closely, if at all. They are not simple addons, they have a learning curve. The real A model was underpowered. No surprise there. That's why the D/E with the Allison TF41-A-1/2 engine was introduced, among other avionics enhancements.
The A-7 models are rich with real-world limitations (try leaving the throttle at 100% for too long - see how that how works out) that make you have to fly the plane closely and accurately. The real world aircraft was a complex aircraft, and their system modeling reflects that.
Until real world experienced military pilots with type ratings affirm claims of bad FDE, I'm more inclined to maybe double check that I'm flying the plane according to the manual ... just sayin' ....

ps - I agree the A-6/EA-6 VC is getting a bit long in the texture-quality wise (remember this model is quite a few years old), and it has bugged me that they painted the EA-6A in Navy colours, when it served operationally far more numerically with the Marines ... That's about the extent of any FSX Razbam gripes I have
