welllll, the release date just got closer..
Razbam contacted me saturday and explained that the gentleman who was working on the flight model for the A-7 was unable to complete it because of some real life situations, and they asked me if i would finish it. Naturally, i agreed. Over the following 30 hours, i compared the FDE with documentation from rolls royce, Allison, The department of the navy, everywhere. Some changes had to be made, but not a lot. Number by number thus plane is completely accurate. The high landing speed ( 145 knots over the wire ) took us by surprise. Natops reported that the trim tab on the plane could if used carelessly cuse the plane to pitch rather dramatically, and well, we learned that one the hard way, so i tamed the trim adjust down. ut uses very tiny steps. Perhaps the biggest surprise though was an error that turns out not to be an error.. I had just handed off a new version update to Razbam and was working on ampther part of the flight model, when i get this call from them about the engine overheat lamp coming on.. Now, mind you this plane has compressor stalls ( we all learned that one the hard way too ), and i was pretty deep into trying to massage those out (because they are NASTY! ) when i got the message, so, i started going back through the engine, pulling up diagram after diagram of the TA-41. All our temps were right, all the pressures correct. I double and triple checked every one of them because it was driving me looney. Nothing i did could make that light go out. So i conferred with Razbam on it..
Now, That light comes on at 585 knots. Natops says to never power this thing above 585 knots ( it can reach 700 knots in an reduced power dive from 33000 feet ), I sort of jokingly said that hey, if natops says not to go that fast, maybe this is a good warning to not overspeed.. They agreed, and I signed off on the FDE as complete.
After i hung up and was sitting back decompressing from one of the most intense weekends of my life, i was browsing through the NATOPS for the plane, and sure as hell, there it was. An advisory in the flight operations section to stagger your thrust due to TIT/TOT overheat causing the engine fire lamp to come on.
Now, I dont know what magic happened here, but when lights start coming on all of their own acord, and trim tabs start moving the plane according to specs, thats kinda spooky in a very good way. It is definately one of the most accurately done aircraft i have ever worked on. It flies by the book, litterally, and even has the same problems mentioned in the book. Razbam does not believe thus is a good beginners plane. Its a bear to fly at first and i guarantee untill you get accustomed to landing at 145 to a170 knots it'll kill ya, cuz the compressor stalls and the plane turns into a brick. Flaps are to be used until at LEAST 175 knots and retracted at 220. Thats by the book, and you dont try and fly this thing slower than 155 knots. Remember also, this is a Navy plane. You dont flare on landing.
OH and how does it fly once youve learned how to handle her?? thres no way for me to describe it without getting all mushy and poetic. I flew her from Kos to Illium and over to Athens last night, and she performed beautifully.
Hope you all enjoy her when she gets released..

....which means we need a 2 seater FAST...
I´m proud to have Warchild as part of this project, her inputs, knowledge and most definitely dedication has been a decisive point towards the kind of accuracy we are looking into this project and future ones.I would look closely to any add on with the FM stamped "Warchild made", it´s most definitely a badge of excellence.
Best regards

: Wait till you try to land this thing and have it stall and drop you at the end of the runway. Then tell me I'm the best :: .. Nahhh.. really, its you folks that are the best. If it wasn't for all of you, FSX would just be another piece of software.. I'd probably be out off-roading it in my jeep.. But you folks make all the difference in the world.. really, you guys are the best ..

Just to add to Warchild's efforts to ensure accuracy, I emailed her post to my friend, Fred Sanders, CDR, USN, Ret. He confirmed every detail!
This Corsair II far exceeds my expectations. I began talking to Ron about this project over three years ago, and I am amazed at what he has created!
Being a bachelor is a good thing now. The amount of time I will be spending, flying SLUF would be a strain on a marriage!!!

Sounds alot like the Alphasim F-105 in that you need to keep the speed up on it, Landing at almost 200 Knots kinda gives ya a good idea as to why that Bird Used a Drag chute, But Really Warchild, You have brought some Clarity to a Cloudy Situation, I do Appreciate your Efforts.

Is there an AOA indexer guru in the house?

As in, know what it does, or knows how to code one? This doesn't, mayhap, have to do with the fact that it appears to work backwards from, say, the FA-18, does it..?
