cfs modding

Will do that JonJ, be sure.

I know that it's possible to experience it with CFS 1, since I've flown the Sopwith Camel, after making the Elevator/Aileron/Rudder Efficiency Tables all equal to 0.75 ( putting all the values in a straight line), and the torque was amazing!

But I didn't fly it before I made that change, so I don't know if it already had a fabulous torque before I messed with those values.

I'm going to try it with the Bf 109, to see if it works with non WWI biplanes (don't know if the MS engine makes a special case out of them).

I'm just beginning to tweak this thing, I'll keep posting with the developments.

BTW, great skins you're posting at the Combat Flight Center. Keep it up!

Best Regards

...Looks like I have to eat my words... J Bekwith released a new version of 'Airwrench'... I'm trying to obtain a copy; the 'Preview' has a tab for torque, I really don't know however if it is good for CFS-2, as airwrench was made for MS sims from CFS-2 on...

There are places in the .air file for data such as prop wash effect on the wings, rudder and elevator... I believe this is where you 'tricked' the game... and it is not a bad idea...

There are also prop MOI settings, prop diameter, gear reduction... even 'mechinical' friction; but all they really seem to effect is data as it relates to the .DP, and throttle responce, such as how long it takes for your engine to ramp up... Or if your engine is OK after boost...

On the ground if the above is done to a Lighting, after setting the rotation of both to either 1, or -1, (pls use 1.0 thrust as above is a typo), there is plenty torque, once the wheels are up, plane in the air, nothing happening... OK something, but at 10 time power two engines, torque appears during a speed change, but not in steady throttle flight...

I'm eating...

JB's Airwrench has 'activated' torque!!! WOW!!!

I figured out how he did this...

Previously; the reason making chages to 'torque' values did nothing is containted within the 'SITUATIO' folder...

The 'model' for 1, 2, 3, 4 engine flight 'dynamics' are contained within files called defair.flt defgnd.flt.

Openable editable with notepad, I use this file to alter many 'hidden' game settings, such as 'turning-on' airframe stress values, etc. Within these files are 'blocks'... heck, see below...

Previous to 'Airwrench' this value was law... Unless you write code directly, bypassed using AirEd, or Abacus FDE. The 'macro editing engines' within these programs have altered the .air files only. What JB has done with Airwrench is 'fantastic' as it writes code in both the .air file as well as the .cfg for each aircraft. The info written to each aircraft's .cfg file allows us to 'bypass' the imbeded model above.

Uh Oh...
I can't fly!!!
It has 'activated a hole lot of stuff... P factor, prop wash... Wow!!!
This is going to take time to play with...
Hats off JB!!!!

Hey JonJ,

You're saying that if I edit the files in the SITUATIO folder I can get more torque? I can leave the airfiles alone and simply edit the default files in this other folder?

You're using the registered version of AirWrench? Is its documentation the source for this breakthrough?

I've not messed with this part of the defair.flt defgnd.flt files... every plane in the sim uses these guidelines, or references... fixing one, messes up all others, I've assumed.

From JB's Airwrench paperwork...

In the older versions of MS flight simulator, most of the aircraft parameters were located in the 'air' file, but
as the simulator evolved from one version to the next, much of the air file content has been migrated to the
aircraft.cfg file.
Although the flight simulator needs both files to run, FS2004 aircraft.cfg files contain all the aircraft
parameters AirWrench needs to compile a corresponding air file 'from scratch'.
At run time, each version of the sim looks in different places in the two flight dynamics files for various
parameters. The key to getting a single set of flight dynamics files that works correctly across multiple
simulator versions is to ensure that all parameters in the air file and aircraft.cfg file are consistent with one
another. No other flight dynamics tool ensures this consistency as well as AirWrench.
AirWrench will generate flight dynamics for FS2002, FS2004, CFS2 and CFS3. Older versions of the
simulator (FS98, FS2000, and CFS1) are not backward compatible with the versions supported by
AirWrench. In some cases, AirWrench may be able to upgrade older flight dynamics to current standards,
but the updated flight dynamics will probably not work in the older simulators.

...The airfiles .air produced for CFS-2 using Airwrench, with torque, are unflyable... so far. This may be due to many reasons, trim for example, but my first 5 or so hours lead me to the conclusion that I must start tweaking the .cfg files, by trial and error, or torque just may not be possible in CFS-2. So far, the added 'math' for the applied torque is rendered at all times, at all speeds, weather the throttle is moving or not, regardless of power level; for example I entered into a 'flat spin' at engine idol, at 10K feet, as there was no way to rid myself of 'torque' unless I killed the engine. Still the plane pulled left.

Yes I'm a registered Airwrench user.

I modified the default .flt files, and I didn't see any effect on torque. There are some interesting parameters there, like airframe stress, that I will try and modify. Maybe we'll know for certain, wether or not editing any parameter in the file changes anything.

You will need to activate all, but this does not mean they will work. When I was writing in the 'real' forum I described mods I did for my CFS-2, the data and work involved... Anyway long story short... most planes do not contain data to run the 'reality' settings within their .air files or .config files, or .dp files. They need to be added to the aircraft. You may have seen ... 'Reality-X' aircraft for example. These aircraft had a 'module' within their .dps, .air .cfgs as well as 'runnung' a 'macro' that pointed to, and gave 'reference' for Airframe stress... these activated parameters permit these 'macros' the ability to introduce math, but do not provide the math.

If the game provided this info... man that would have been great. CFS-2 may still be alive...

Activating, or changing the above numbers in the 'engine.1' window will not effect any aircraft that does not point to it, except on the ground, and during 'quick' combat at mid air start up, however the reason I do not play with this is there are a number of aircraft I have that do... And every .air or .cfg uses these parameters, some of them (most do not point to 'torque' therefore I had you play with 'power' 'thrust' within the aircraft's .cfg), if not all. If you open, if you have, Flight-1's aircraft, newer than their P-40's, there is no air file. Yes there is a place holder called an .air file... but somewhere in the very simple, but unlabeled .cfg are the pointers to the embedded CFS-2' codes it uses.

My understanding of the code in the engine windows are they are implemented upon the start of a flight, the aircraft author then chooses which values to continue and which become inactive, either at 'wheels-up' or the compleation of engine start if you are in the air. Haven't you noticed the only time 'torque' comes to play in the air, is during a switch of aircraft in quick combat or free flight.

Thanks for the info JonJ. I'll see what I can do with AirEd, and continue to experiment with it. Airwrench should probably be a much better tool for the job at hand.

...here are some cool things, commands thier 'lingo', to play with in your .cfg files... to help you 'tweak'. Better than making canges in the .air file... Commands that let you 'tweak away' in 'plane' talk... From a .cfg that 'torque' was added, but as I said the aircraft is not flyable... Think of the .air file as your 'starting' point... These 'catagories' are to be entered after the 'flight tuning' headder; the below examples are taken from my F-1 P-51 I told you I added torque to, using airwrench, but the plane was unflyable.

PS >> Data entered into the .cfg has more 'weight' or importance than the .air file in CFS-2, however the .air file is 'manditory' even if it only says go back to the .cfg, in essence. In CFS-2 there are still .air file 'only' commands or data that will not be accepted unless in the .air file. You will also notice 'airwrench' catagories... For the moment, I do not know how these work. My guess at the moment is these 'catagories' are place holders for 'Airwrench' commands upon opining the .air files.

Happy Holidays!!!

I'll try that with CFS2. For the moment I've been concentrating on CFS1. One thing I've found out is that the most 'torqued' airplane in CFS1 (the Camel) is just a converted FS98 airplane. The air file has a lot less records, some of which simply don't exist in CFS1 or 2. So, I've been backtracking (it's almost a voyage through time and I am know examining FS98 aircraft. I've read people saying that after FS98, microsoft has been making a larger, and larger mess of the code. It's probably the price to pay for retro-compatibility.

I've been enjoying this conversation, but I may be leaving the forum in the near future.

Whatever the case, I'd like to tell you that it's been a pleasure to meet you, and if not here, I will be discussing this with you on some of the 'real' forums about CFS.

How is New York today? I wish you a very happy holiday too, JonJ!

... Don't be silly... the pleasure has been mine! Safe Journey! Good luck!

This is not the screen shot section... but I don't thik anyone will mind... I hope. As a good-bye present... my latest 'skin' 1st historical one...

Detriot Miss in CFS-2

On second thought please go there...

Thanks JonJ, likewise! Great skin, lots of detail. See you there!

...Well my friend, I continue to eat my words. I've been tinkering with AirwWrench and learning to apply FS-9 commands to CFS-2. Built my 1st air file with torque. It's very hard to do, but now I can go back and re-mod the others...

I stumbeled on how to do this due to Airwrench, and... I purchased a La-9/11 set for CFS-2/3 FS-2002/4 that 1st didn't work only in CFS-2. I went to the site found useres had been looking for a fix for over eight months... I repaired posted a fix, which was applied by the 'vendors' in thier patch. Then I found I could not take off or land with her... I just posted to the vendor a repair. The author of this Lavachkin package 'gets away' with creating new CFS-2 aircraft by creating one master .air, .cfg .dp files that operate 'cross platform' with little or no modifications. I firstly was amazed to find the plane worked at all with these 'strings' in CFS-2. Things 'took-off' from here.

Let me know if there are any planes you own, that I may own, I'll work on them 1st. Below a screen shot of Detriot Miss in 'final' paint, the next to recieve torque, the LA-9M, the aircraft that I 1st applied torque.

Hey, I thought I knew CFS1 a bit, but I can see there is still a lot to learn and understand.
To tell the truth,(shame on me), I had never tried to open the .flt files as I though they just contained info about location, altitude and things like that...
How can I know if a CFS1 a/c flight models refers to values contained in .flt files, and which .flt file?
Thanks for any help.

The .flt file is really a left over from FS98.Its not much usefull in CFS1 unless you use the save flight option in CFO. It saves your situation and when you select a previous flight. Your aircraft is returned to the same sitiation it was in when you saved it. I fooled around with it, ("editing it") but it really only is usefull in single player. For multiplayer its pretty useless.

Welcome, Herr Oberst.

It has quickly become one of my favorite places for information. Glad to see you here, your skills will be an added resource I believe.
BTW take a look at the convergence charts Rugger posted. I am sure they will be quite usefull.

Rall

Vince, the best all-round CFS1/2/3 forums are at Sim Outhouse - it's the most dynamic, creative place I know. Try it out.

Sim-Outhouse Forums - Powered by vBulletin

Thanks ndicki; I'm also a SOH member.
Oh by the way, whenever you wonder why JG57 Rall and I call each-other 'Herr Generaloberst' and 'Herr Oberst', that is because we're both part of the same CFS1 squad which is called Jagdgeschwader 57.
That's our respective ranks. Rall was the creator and is the main instructor of JG57 and has the position of Geschwader Kommodore, and I'm the Teknisches Uffizier and Geschwader Adjutant. JG57 is one of the current most active CFS1 squads.

I'd guessed that was it.
