Guesswork is good if realistic. Ultimately would you believe all FSX aircraft are based on guesswork and necessary compromises due to simulator restrictions. It is remarkable how many mil jet aircraft used to be the same in prior versions of MS Fsims. So much so that I gave up giving them a try - mostly they all flew like LearJets!
If anyone tried to model a Navy aircraft most often it was wrong in that the (A4) spoilers would act as inflight arrestor gear or there was no usable AoA Indexer etc.
However the FSX Hornet - modified - changed all that. Unless you yourself have flown a similar model Hornet; you will be guessing also about what is good/bad. For my reckoning though it is really good - especially in the FCLP/Carrier Landing config. The only thing that matters.
Yes I have seen that Thunderworks 'endless in develpment sim' about Falklands with A4s. Good luck to them. I have never flown a realistic A4 Sim model but the KAHU is getting close, especially the airframe model is excellent. However my vote goes to the SLUDGE & Goshawk for good times in FCLP/Carrier Landings. If I need to use a combat sim I'll buy one thank you. For shear fun "Pacific Fighters" was fun for max stoush 16 v 16 and prop carrier landings to boot.
