I just spent the last 3 days tweaking/porting the old Razbam A-4 packs 3 and 4 into FSX. I ended up throwing out a number of models and repaints to skim down the size of everything and ended up with several of the 2 seat versions, the A-4E/F/L and a couple of the Israeli models. Overall I am impressed with how they turned out. I tweaked the cfg and replaced the airfiles with the Frat-Bros A-4K airfile and it worked perfectly being stable, well handling and overall close in the numbers. The only texture change I made was adding an environment map bmp file to each texture folder which I do to all portovers. I also used the Frat-Bros A-4 sound file which is excellent. The gauges work well. The thing that amazed me was that even though these models were never intended for FSX they were all super stable on moving AI Carriers both in traps and in launches. There may be plenty of imperfections present in these portovers but for now they will hold me over until the arrival of the new Razbam A-4's which I will be buying the full sets of. I bought packs 2,3,4 going back to 04 and later(never bought or even seen pack 1 in sim) and all were money well spent. Glad I saved them on disk. FPS performance was excellent!
