Got it, thanks. As I was reading it over I was wondering about the weight and balance section of the CFG
[WEIGHT_AND_BALANCE]
max_gross_weight = 26200 // (pounds)
empty_weight = 16145 // (pounds)
The lit refers to a max of about 60000 lbs. Do the numbers in this balance section really show FS simulated weight? Did the author mean that his 26200=60000 in FS? Is FS architecture set up to understand pounds, square feet of wing area and the like realistically or is it up to the aircraft modeller? Before I get into it I need to have the right starting points. I can just use what is there but if I'd rather use real-world numbers if possible.

Not quite. I have always wondered if those values entered as max_gross_weight and empty_weight in the CFG are true pounds in the creation of the model. If they are then I should change them to reflect reality. If they are not and do not try to relate to real weight, like a value for roll stability has no meaning other than a scalar effect value, then I can just alter them as needed to produce a result. Does that make sense?
So far I've loaded Miltons update then started making adjustments to make performance follow the manuals information. I am at the point where I try to simulate 60000 to 70000lbs of weight and need to know if those CFG weights are trying to be real or not. I think I can pretty much have it fly well no matter which way I go but for those who want to play with payloads I would prefer do it the right way.

Use all real world numbers. The SDK says this:
max_gross_weight = nnnnnn pounds: Maximum design gross weight of the aircraft. This parameter is used solely in FSEDIT to help determine the aerodynamic coefficients.
empty_weight = nnnnnn pounds: Total weight (in pounds) of the aircraft minus usable fuel, passengers, cargo, and expendable armament (Combat Flight Simulator aircraft). If not specified, the value previously set in the .air file will be used.
Also, recompute the MOIs

Thanks Milton. So I will alter those numbers to reflect actual weights then go at it again.
I am curious as to which engine you will model for, the 3350 or 4360 ...
The aircraft.cfg engines are confusing looking at the statements:
[piston_engine]
power_scalar = 1.0 //Piston power scalar
cylinder_displacement= 130.71 //Cubic inches per cylinder
compression_ratio= 6.7 //Compression ratio
number_of_cylinders=14 //Number of cylinders
max_rated_rpm= 3700 //Max rated RPM
max_rated_hp= 1200 //Max rated HP
That is not a 3350-85.
Even data about the 3350's differ in places regarding HP:
R-3350-85 : 2,500 hp (1,900 kW)
R-3350-89A : 3,500 hp (2,600 kW)
R-3350-93W : 3,500 hp (2,600 kW)
Most of the 3350's used were -85's but some say 3500 HP which were -93W's. I think the -85's were most prolific and later some 4360's.
I suspect the 3350-85 is the most likely choice.

Sorry for the delay, I was hijacked by the missus for the usual work to do stuff. After reading sections of the manual, I was still unsure of some of the weights. At one point it discussed a fictional flight to drop 19000 lbs of equipment so I took that as an upper limit for payload. That plus the empty weight and full fuel load (4200 lbs) I got about what I was reading was the max takeoff weight of about 70000 lbs and an empty weight of about 46000 lbs. What I've done so far is use Miltons update, changed weights to the above values then went to work on dynamics. Currently it will rotate and takeoff at about 100-110 kts, cruise at 200, and land full flaps approach speed of 98-110 mph depending on loading. I changed up the station loads to just three with the last one usable as payload (19000 lbs max).
Two snags I can't seem to make right are 1: I can't seem to make the landing gear soften at all on landing. It hits hard and drops the nose gear to the runway too fast. 2: I had to make excessive elevator force to enable rotation (related to #1?). Something just made it not want to respond to a normal elevator scalar value. Having to do this this made other values changes necessary to compensate so it wouldn't pitch like a butterfly in a gale on elevator input, a bit crude but effective. Overall it seems to fly pretty well. The original model didn't have the problem as much. As for the engines I defer to others more knowledgable in that area. I only changed the power and thrust values.
Time for some testers. Below are my changes. Copy and paste them from [general] on down since I don't know what textures people have. Give me some feed back and we'll get this done.

Two snags I can't seem to make right are 1: I can't seem to make the landing gear soften at all on landing. It hits hard and drops the nose gear to the runway too fast. 2: I had to make excessive elevator force to enable rotation (related to #1?). Something just made it not want to respond to a normal elevator scalar value. Having to do this this made other values changes necessary to compensate so it wouldn't pitch like a butterfly in a gale on elevator input, a bit crude but effective. Overall it seems to fly pretty well. The original model didn't have the problem as much. As for the engines I defer to others more knowledgable in that area. I only changed the power and thrust values.
Time for some testers. Below are my changes. Copy and paste them from [general] on down since I don't know what textures people have. Give me some feed back and we'll get this done.

She flies pretty well for me, takeoff was no issue lifting off smoothly nor was the landing without the nose slam you mentioned. Touchdown should be around 85-90 knots depending on weight.
However, I would recommend increasing elevator trim range to 20:
elevator_trim_limit = 20.0 //Degrees
And, correcting the CoG from 37% MAC to 25+, I used this to move it:
wing_pos_apex_lon = -13 //Feet, longitudinal distance from reference point, negative going aft
And, changing the engine section as Sunny9850 suggested with the 3350-75 parameters as a start. Cruise is in the ballpark of 227 kias at 32" MP after that change.
Drag seems too low now with the increased weight, both parasitic and induced, but I had no issues getting her to slow with patience and a flatter approach.
Lift from flaps seems weak once speeds get to short final ... keeping power on is essential for the lift but then the weak drag creates a speed issue.
Hope this provides another perspective for you.

Hello all:
OK lads, got a problem.
I like the bird and in the past I tried to do something with it (wishful thinking!!) the results are better forgotten :isadizzy: so I decided to follow the advice of the gurus.
Took careful note of the whole thread, dutifully copied all the archives and merrily started configuring the beast.
Try 1: Got Aeromed cfg, added the modifications from Milton and the engine section from Sunny9850. Airfile beech_baron_58. Got to the strip, fire the engines and throttled up. Sweet Jesus, left behind the SR-71 in the paralel runway, the airframe was vibrating (first time I've seen this in FS9) flying like a bat out of hell... The experiment finished when I overstressed the airframe by overspeeding when climbing at 1300fpm on cruise settings. Oops
Never mind, me bad
Try 2: Got Aeromed cfg, added the modifications from Milton and the engine section from Sunny9850. Airfile Fairchild C119 (the original, me thinks). Got to the strip, fire the engines, throttle up. Calm, relax, it is bound to accelerate... give a shave to the squirrell in the tree at the end of the runway and at 100mph, balls to the wall, AoA was over 5 degrees, climb rate zilch and unable to accelerate except in a dive (I think, was not high enough to try!!)
Now, all this seems to indicate that I'm doing something wrong.
Can somebody tell me which combination of air file and aircraft.cfg are we talking about so I can follow the development, which BTW i find pretty interesting, and that the bird desserves.
Thanks in advance chaps and again thanks for taking up the subject, you made us proud!!!:ernae:
OK lads, got a problem.
I like the bird and in the past I tried to do something with it (wishful thinking!!) the results are better forgotten :isadizzy: so I decided to follow the advice of the gurus.
Took careful note of the whole thread, dutifully copied all the archives and merrily started configuring the beast.
Try 1: Got Aeromed cfg, added the modifications from Milton and the engine section from Sunny9850. Airfile beech_baron_58. Got to the strip, fire the engines and throttled up. Sweet Jesus, left behind the SR-71 in the paralel runway, the airframe was vibrating (first time I've seen this in FS9) flying like a bat out of hell... The experiment finished when I overstressed the airframe by overspeeding when climbing at 1300fpm on cruise settings. Oops

I'm going to post some new flight models in a bit. Should fix all issues.
First will be a C-119-C/F with P&W 4369, Aeroproducts 4 blade prop.
I think with the different mdl's we've got, and the different performance values between engines and props, I'll issues files with the idea that different planes will be divided into separate folders. these will be unfinished betas, Flightsim enthuisiast's input required.
Probably put'em up in a few hours.
Who knows the signifigance of Daisuke's long nose/ short nose models? I remember the RCAF running C-119 G's with long nose...I imagine all weather radar. Was this specific to certain models, perhaps late fifties, early sixties??

The long nose housed a radar antenna for weather and navigation. They were used by the Canadians and the USMC. Checking in Aerofax's C-82 and C-119 reference book, I can find no other military operator's of these versions. Post military service, the Canadian C-119s were flown as fire tankers and retired from that when banned from fire fighting due to structural fatigue and failures. Looking forward to your updates!

the pair still hauling freight in Alaska are short nose variants. One regular and one with the aux jet engine...
Nice website about the planes.

Okay. These are some files that I started about a year ago when I rediscovered Daisuke's C-82 and C-119 models. I recalled that Jay McDaniel ( Farmboy) wrote a flight model update for the C.82 Packet. It's here in the library, so I downloaded, installed, and liked it.
The C-119 was lacking, though.
Reading this thread gave me the kick required to refocus my effort. This is really an attractive and well done visual rendition of such a legendary craft. (See Brian Gladden's link above....amazing still...!)
So, okay. We've got a pile of MDL files, long nose, short nose, three blade, four blade, a kerosene burner on the roof.....yeah, yeah, yeah.
Let's make it simple.
Let's begin with a new folder. Label it something like C-119C, or C-119C R4360, or whatever you like, as long as it's distinctive and easy to remember, easy to find.
Copy into this new folder (From Daisuke's original C-119 folder) the folders labeled,"model, model.nose4prop, panel, sound, and texture." Add the files from the zip attatched here, and you've assembled the basic kit for a Fairchild C-119C with Pratt&Whitney R.4360's, and Hamilton Standard four bladed props.
That I would describe this as a "C" model airframe, please note that I do this loosely. Let's say it's a facsimily of "C", the essence of Pratt&Whitney.
I wanted this flight model to have a family feel comparable to Jay McDaniel's C-82 physics. Some of his entries have been referenced to maintain a likeness, as if they existed in the same universe. It is...a flight simulator....even if only for the desktop in a massively destandard real world techie manner.
What to look for:
I've quoted limiting specs from an FAA data sheet issued in 1970. Operating speeds, etc. The plane will easily exceed those. It'll run as it would have in the early nineteen-fifties. FlightSim doesn't seem to recognize the octane rating (or lack of.....)from those generic little fuel pump stations that populate the flightsim world. I wouldn't over-run one of these old ladies in real life, and it'd sure be nice to nail down some sort of gauge that would punish flyers who ran her over fifty-two lbs on takeof....etc,etc.
A gauge that could program a prop runaway or involuntary prop-reverse could be a hoot. Fouling fifty-six sparkplugs or generating an magnesium case fire that melts a wing spar in fifteen seconds would be a....ummm....well....let's forget the magnesium flare effect, and just focus on trying to replace fifty-six spark plugs in an eight hour shift.....
And..... that's all beyond me...I table those whims as a distant wish.
I did find a conversation over at Cal-Classic regarding a gauge in the new Convair C.340 that provides cowl flap drag....good one to try later.
As well...I'm at a bit of a loss for the moment as to how one could evoke reverse pitch on a piston engine prop in FS.
Again...some talk about a Martin Bar in Cal Classic's DC-7C.....heady stuff for a guy who spends most of his time in France and Italy floating around in biplanes. That'll be looked at later. Anybody want to dig in now, I'd be happy.
What to look for here:
I'm uncertain about the flaps. They seemed small for the plane, and yes...real world pilots have mentioned that. Did I create a believeable effect here? Do they generate enough lift, drag....too much(?)....does the plane pitch the right way......believably?
Fuel......I've got FAA data on fuel tank capacity, I know this tank sits in the wing outboard of the engine nacelle, that tank sits inboard....but then there's a pair that sit within the fuselage....but where? I put them up top, inline with the other fuel tanks, away from the cargo area, where the main spar passes through the fuselage. It seems a logical guess.....would they be there on the real aircraft?
The cargo bay.
She's got 10,000 pounds of stuff to haul by my default. Seems reasonable. To keep the plane balanced, I've loaded her like this:
Cargo Bay Payload Points, 1000 lbs each default:
(Points 0-2 are flight deck crew.)
+14 feet CoG, lateral placement, 3 ft. left and right of center, No's 3 and 4
+8 feet CoG, lateral placement, 3 ft. left and right of center, No's 5 and 6
+2 feet CoG, lateral placement, 3 ft. left and right of center, No's 7 and 8
-4 feet CoG, lateral placement, 3 ft. left and right of center, No's 9 and 10
-10 feet CoG, lateral placement, 3 ft. left and right of center, No's 11 and 12
...With this data, the user can modify the loadouts through FS, or go right into the Aircraft.CFG and create heavier and/or more concentrated loads and easily maintain an effectively balance aircraft knowing the relavance of each load point to the aircraft's CoG. Users with the ACM program can simply load up the C-119 and visually randomize the load pattern with even less effort.
Next I'll work out a Curtiss Wright powered plane, a later three bladed prop variant, and then look at those jet-pod things. I haven't the slightest idea how to render a multi-type powerplant aircraft in the flight model.
Just approximating the thrust with an average of "three" piston engines seems disatisfying. My mind wanders back to gauges. Could an XML guru come with a way to evoke an auxilary jet turbine, and trigger a separate sound set as well as the thrust value, repleat with throttle lag?
Hmmmm.
Here's the files. Have at'er boys. Let me know what it does on your FS setup. It's just beta, I'm open to changes any which way but loose.

oh yes, one last point.
Effects.
I always fiddle the effects as planes come aboard the little world in my computer. When releasing a flight model, I always rewrite to flightsim default (yawn) effects so users recieve a standard treatment. Many will trick out the effects to suit themselves afterwards.
This aircraft.cfg still has a few non standard effects entries.
[effects]
wake = fx_wake
water = fx_spray
dirt = fx_dustrun
concrete = fx_sparks
touchdown = fx_tchdwn, 1
contrail = fx_wop_contrail_s
startup = fx_wop_engstrt-b29
windshield_rain_effect_available = 1
Dustrun is by Bill lyons. It was included in most of his releases, and is still my favorite way to evoke a dust devil in FS. Available wherever Bill Lyon's aircaft are downloadable.
A couple of entries pointing to Wings of Power aircraft effects, the B-29 startup puts the exhaust in the right place....if indeed for an impossibly tight and clean starting compound-radial mill....
If you don't have the Wings of Power b-29 installed, or Bill Lyons "dustrun" effect, be aware you need to add something of your own.
....also....this entry:
[smokesystem]
smoke.0 = -8.0, -50.0, 15.0, fx_nicks_watrsnoland_m
smoke.1 = -8.0, -50.0, -15.0, fx_nicks_watrsnoland_m
.....Gee....I remember that vaguely. Some amazing effects under Nick's name...but this one doesn't click. I wonder what it did...? I'll check it out tomorrow after work. In the mean time, users be aware....change it if the effect does nothing in your sim.

Excellent magoo ... will check it out. 
EDIT: WOW! Just took her through the flight tests ... everything feels perfect through all phases of flight and taxi. Very stable, believeable, expected responses were right on in drag, pitch, yaw, and throttle responses. Induced and parasitic drags seemed perfect. Pitch from gear and flaps were right on re: my expectations. Takeoff, climbout, crusie, approach, and finals were perfect for me. Excellent work all around. Thank you very much Magoo.
)) This is a keeper. I did not give much attention to the ancilliary things but will check them out later today. The lights look great and sitting static on the tarmac and suspension is much better.
