It really looks fantastic.

Is there a paint kit? I didn't see any reference of it at the site.

Sure, the installer includes a paintkit (3 large psd files)

.....this is incredible. I love it. The only thing I either don't understand (or wish were better) is a way of monitoring engine power (% gauge) so I can avoid destroying the engine.

I'll tell you this-- the A-7K is a NO-BRAINER!!!!

This is WONDERFUL!

Thanks, Prowler....

P.S. Can we get the travel pod option on the -K too, please?

Hi gents:
1st all thank you all for the comments, it´s great to see you´re enjoying it, as i stated before, you do feel the lack of a manual, that´s in the works.
As for those small bugs, i will fix them and issue a patch.
BTW, Zeus here is our main coder, so all the instrument/weapons magic is his work, so hats off to him for an awesome work, also any questions regarding those, well, he is the guy (i just pull polys, lol)
Hats off also to Pam, great work sweety!

Repaint kit:
There is one, you should look for a RAZBAM folder in your main FSX folder, in it you´ll find 3 psd´s.

Once again, thanks, and..well...no pics??

We are very glad that you like it. The tachometer is located below the TOT gauge in the A-7D and to the right in the A-7E. You can monitor engine %RPM with it.

I'm getting a RAZBAM file with no extension as well in Firefox, I had to switch to Internet Explorer to get it to download properly.

**Warrant** · August 14th, 2010, 07:22

Just got it. The droppable bombs (especially the high drag ones) and the extremely cool appearance of the bird got to me.

Off to fly her, between painting F-35's :salute:

I run firefox as well, but it downloaded just fine. Do you have the latest and greatest from Firefox :ques:

Hi,

Just finished a looong flight, by my standards at least, lasting close to 90 minutes and this thing is excellent. If you remember to keep below 96% RPM you should be good in most situations .... and yes, I am still a chicken and have not been to the boat yet

Thanks again Ron and crew, this is my favorite

Folks, before I pay and download what are the system requirements? Will this run on FSX SP2, and without a joystick? Looks like an absolutly fantastic adder to the collection.

You can fly it without the joystick, just remember that this is not a plug-and-fly aircraft. As for the SP2, I'm not sure. I used some events/variables that the SDK claims are Acceleration-only.

Great work, RAZBAM!
Super FDE, Pam!

Yup, already scheduling them, A-4´s were delayed due to new standards, next product will be improved even further..

Any Idea what makes my compressor stall just after take off? Something seems to happen below 1000ft when I go from mid range to MIL or something.

Thanks

accumulated/induced drag is the first thing that comes to my mind. It's not really a compressor stall as i first thought, but it may as well be.. I was having very similar issues in what may be the same exact location ( metaphorically speaking of course ).

On takeoff, I always make a climbing turn away from the runway. Normally, on any plane which has zero or some dihedral ( where the wings are angled upward as they move out from the fuselage ) the air that is incountered on the underside of the wing flows back and outwards towards the tips, so, in a turn the air hits the bottom of the wing, and flows back, outward and past the wing, rather freely. Although there is some degree of drag piled on from the increase in in surface area ( in relationship to the flight path ) it doesnt become any real issue till the aircraft is at so nose high ( in relationship to the path of flight ) that it is no longer really using its wings at all as anything except big flat walls in the wind.

The A-7's wing angles downward from the fuselage as it moves out towards its tip. We call this Anhedral. In effect its upside down. There's a lot of reasons for this plane to use anhedral such as maneuverability, but it does have one litterally massive drawback. As your angle of attack, in rlationship to the direction of travel increases, The air hitting the underside of the wing is no longer happily flowing past and outwards.. it tries to flow past, and inward towards the fuselage. This is because the down angle on the wing causes it to act like a bug cup or parachute. So the air gets trapped up against the fuselage under the wing, doesnt go anywhere because theres nowhere to go, so, it builds up forming a large mass of compressed air ( weighing an unknown thousands of pounds ) which disrupts the flow of air under the wing, stalling the aircraft. The engines, may as well not exist at that point. There is no amount of force they can produce that will overcome that amount of drag. It would be like trying to move a freight train with a motorcycle engine. it just isnt gonna happen, so the plane stalls and falls.

The NATOPS says it takes four to six thousand feet to recover from one of these stalls. It even gives an altitude chart for recover-ability. Everything below 4,000 has a big X in the box. it means your dead.

So how do you deal with it??? well, there are several ways. The easiest is dont turn the plane untill you have attained a speed over 200 knots. the next easiest is if you have to turn, dont pull back on the stick, at all. just bank the plane and let it turn on its own. You'd be surprised at what your hand is actually doing with that stick when your not paying attention ( please guys, no puerile jokes ). The hardest way is to watch the IAS for a drop in speed. As the speed begins to drop, let off on the stick and drop the nose till she regains momentum. With practice you can get pretty darned good.

Now, there is one last thing that you can do to help yourself in addition to all of the above things.
In the aircraft.cfg file there is an entry called thrust_scalar. When i create fde's all the scalar values get set to 1.0. You can increase that scalar minimally ( to 1.25 )and achieve some very satisfactory results. What the value does is this..
While sitting at idle, you have zero thrust, so there is no change in thrust at all, but as you increase thrust to 100 pounds, the actual thrust increases to 125 pounds. at a thousand pounds the actual thrust would be 1250 pounds at 10000 pounds it would be 12500 pounds.
As you can see a little but helps a lot. In the case of the A-7 it means you gotta watch your top end as going over 585 knots is real easy, but on the bottom end, it might just be enough to save your flight.

now, if you do this, dont think that all you have to do is go to full throttle and she'll blow her way out of there.. She wont.. Even though i gave the engines a ridiculously short amount of time for spool up, it still isnt instantaneous. The engines used in this plane and several others from the same time period ( including some F-111's ) were turbo-fan engines. normal spool up time from idle to full throttle was 16 seconds. however, they deliver enough power that the pilots adrenalin/pucker factor can go from 0 to 5 within just a couple of seconds. In a stall below 4000 feet, even on full mil power, there is no way the engines can respond fast enough with enough power to guarantee recovery. Learning to handle the plane properly is the best and truly the only way to avert these situations.

Keep in mind, this plane is classified as a light bomber. She carries one 20mm M-61 gattling gun. Unlike her sister, the F-8 crusader, she cant dogfight for ****. She can however run like hell, and out turn anything of similar size and weight as long as she is moving at speed.

Hope this helps

Very good reading there Warchild, very ;-) I have conquered the bird btw, no throttle-slamming F-16 style and it'll be good :-)

The high drag flaps are called retarders ( or were ).. Soo, first they made smart bombs, and then they made them retarded.. typical military :::LOL::...

Fantastic Dag..
::LOL:: Fantastic Dag.. I'm afraid i still have my training wheels on for this one, but thats because i work on so many planes all at once i dont get to spend a lot of time getting to know any of them. Like today, I'm working on a Stearman, a P-61 and an A-10.. Theres so many differences between those three that i wont be able to get a clear idea about flying any of them for a while yet..

i DID however, install AIcarriers and the USS Nimitz specifically for this bird, but i'm having some issues there too. The entire fleet disappeared off the screen and i couldnt get it back.. :;sigh:; I'll figure it out.

..

Shes a great plane. Ron and the guys at Razbam did an excellent job on her..
