FS2002/FS2004 Fokker D.XXIII. This is a fighter of the Netherlands developed just before World War II. The layout that has two engines arranged front and back in the body. Though the test was begun in May 1939, the low output of the engine and cooling the back engine became problems. The Netherlands surrendered after the invasion of the German army in May 1940, and development was discontinued. Only one prototype was destroyed afterwards or is said to have been confiscated by Germany to use as research material. By Kazunori Ito.

Haven't downloaded it yet but I thought I'd better let you know first.

Cheers,
Maarten

You beat me to the punch by two minutes. Downloading now but won't be able to take a good look at it until I get home from work tonight. Looks promising! :applause:
 
Nice surprise! :applause:

The model seems quite accurate, but the FDE and paint could use a bit of work.

I agree, the model seems very accurate. Evidently Kazunori tried to work up the piston engines
but ran into problems. He expressed considerable frustration in the "Readme".

Many thanks to Ito-san for a great model.
 
Yessir- another nice aircraft from Ito-san!

I was debating whether to work over his FDE files or splice in those from Payakan's D.23 that he made some years ago... it looks like I'll be better off working over Ito's files... we'll see what I come up with...

I thought it was interesting that I found 3 different paint schemes for this- yet only one aircraft was produced... hmmmmmm...

Hate..Hate (FDEs)

Well, it's out: Ito hates dynamics (hehe). What else is new? But the guy does great models, that's for sure. I worked on the dynamics (well....had some already 'configured' for push-pull engine (Junkers EF-112) so used those. Notice air file is 'pembroke'. Rob Peter to pay Paul. I like these FDEs. The sound can be piston or turbo prop. It has reverse thrust (ha!). I'm too good (hehe) .:sheep:

While it's true that Ito doesn't care for piston engined FDE's you gotta hand it to him that he actually tries,and you have to respect that (after all, FDE's are kind of a black art to most). His aircraft have been steadily improving over the years especially in the VC. Other from the FDE all this plane really needs is a BananaBob prop and a rockin' sound file. Preliminary research show that those engines are inverted air-cooled V-12's, like those engines in the DeHavilland Albatross or that Ranger V-something-or-other that was in the Bell XP-77. So, any ideas about the sound file?
 
At this point I 'Frankensteined' Payakan's D.XXIII FDE with Ito's contact points and lights. Not bad. Slow on acceleration, top end 256 KIAS at 1200' and absolutely vicious near stall speed. It's definitely a challenge to get airborne and to land. Otherwise it seems pretty benign.
Since I changed the FDE to a piston engined version I made some changes to the panel.cfg. Most of it was already in place; all I had to do was to comment out the turbine gauges and 'un-comment' out the piston gauges.
I also changed the pixel size to 1024,1024 to make the gauges clearer in the VC. Contact points may need some work or those are some flat tires.
BTW, how does one say 'Mixmaster' or 'Push-Me-Pull-You' in Dutch? I'm thinking those would be cool nicknames for this plane (Yeah I know the Cessna 337 goes by those names too)
Here's the modded panel.cfg:

Here's the panel config I set up for the 2D and VC panels using Mopar Mike's 4 Engine Luft gauge pack (available in the library...may be harder to find than it used to be...CFS2 gauges best place to look). This set up give the front and rear engines their own tach, manifold pressure and cylinder head temp gauges. No radio, ap or GPS stuff at this point....will set it up to reflect my personal taste...but left it out for you folks to set up to your personal tastes.

Will crank out a sound pack for the bird in a bit....based on Lawdog's Stuka sound pack.....really like the way that pack sounds.

I've got several things going on right now including the moving of some archive files, but Ito's airplanes are always fun for me. I'll work my usual changes to get it into FSX (larger textures, different prop blur and redone VC). I do wish Ito would see his way clear to at least do what needs to be done to the prop disc so it doesn't knock out autogen in FSX. That's the only real drawback.
 
Sound & Gauges

I used F4U sound as it's piston engines. Why stuggle. As for the Luft gauges at SOH here is the shortcut: http://www.sim-outhouse.com/sohforums/#download .

Here's some data from my D.23 book:

2 Walter Sagitta engines

Wingspan 11.5 meter
Wing area 18.5 Sq. meter
Length: 10.2 meter
Height: 3.8 meter

Propellor reduction 1:0.666

Service altitude: 4,100 meter
Max power at service altitude: 2x540 hp @ 2,600 rpm
Cruising power: 2x270 hp @ 2,050 rpm

Max. take-off power: 2x465 hp @ 2,600 rpm

Fuel consumption at cruise power: 2x73 kilogram/hour

Empty weight: 2,080 kilogram
Armament: 220 kg
Equipment: 145 kg
Pilot with parachute: 85 kg
Fuel: 290 kg
Oil: 30 kg

Total weight: 2,850 kg

Max. speed @ 4,100 meter: 525 kph
Cruising speed @ 4,100 meter: 390 kph

Range at cruise speed: 780 kilometer
Range with full tanks: 1,020 kilometer

Max. tank capacity: 500 liter

Climb to 1,000 meter: 1.5 minutes
Climb to 2,000 meter: 2.9 Minutes
Climb to 3,000 meter: 4.2 Minutes
Climb to 4,000 meter: 5.5 Minutes
Climb to 4,500 meter: 6.15 Minutes
Climb to 5,000 meter: 6.9 Minutes
Climb to 6,000 meter: 8.6 Minutes
Climb to 7,000 meter: 10.9 Minutes
Climb to 8,000 meter: 14.3 Minutes

Practical Ceiling: 9,300 meter
Max altitude: 9,500 meter
Max altitude on one engine: 5,500 meter

Take off distance with a 2.5 meter/sec headwind: 200 meter
Take off distance with a 2.5 meter/sec headwind to a 15 meter altitude: 440 meter

All this official Fokker data, but I noticed that even in official documents there are slight differences. Only eleven flights were made with the prototype before the invasion.
Test pilot Gerben Sonderman described that the engine torque from the two engines wasn't a problem in flight, but on take off the left brake was used as the aicraft had a tendency to move to the right. Full left rudder was required once the speed built up. Aerobatics were never tried due to the high temps of the aft engine. Reliability was also an issue with the Sagitta's.
 
Ito-San's Readme file

Besides his admission to hating FDEs, has anyone else taken him up on the offer further down in the readme file for the D.XXIII regarding his Bf-109G-6? He says he doesn't plan to release it to the public- just to those who e-mail him about it. Overall (model, FDE, VC) I think it's one of the best jobs he's ever done... Three models (clean, centerline tank, and tank plus gunpods), painted in Finnish colors...

-Mike Z.
 
I worked on the dynamics...

Hello Chuck,
Your flight dynamics are certainly better than my attempts. The D.XXIII is VERY fast
with all those horses so I toned down the power a bit. Ito-san has made an excellent
model of an airplane I very much admire. Your work gave me a very flyable model, thank
you.

John
 
Here is another cfg and air file that work very well. You must use both files together. The sound from the He-111-H6 also works well, I dont remember if it came with the model or made by Lawdog.

Did anyone find a better prop file?
 
Hello Terry,
I would like to try your setup, but the file posted appears to be all text.
I don't know how to utilize this data. Please advise.

Thank you,
John

You cant upload a zip file therefore the use of the TXT extender. Just delete the .TXT then unzip.
 
I gave it a go with Terry's modded FDE. Still a little hot (333 KIAS at 2000') so I toned down the power and thrust scalars and set them to 1.00. Still takes off in a reasonable amount of space but the top end is only 283 KIAS at 1500'--pretty close to the speeds that Ferry found out.
I also found a BananaBob prop from a Bf109--not sure if completely accurate but it looks good.
As for the sound file, I settled with the default DeHavilland Comet. Engine-wise they are pretty similar--both are inverted and air cooled; the Walter Sagitta just has twice as many cylinders, like the Ranger V-770 but a bit bigger (According to German Wikipedia displacement is somewhere around 1120 cid, just slightly smaller than the Jumo 210 that powered early Bf109's)
