...and another beauty, thanks a lot for this one as well Mike!

I was not even aware of this plane. Beautiful! I assume from that skin that it was used by the Dutch (among others perhaps) but was it used in the Dutch East Indies by chance?
-
Yep. I mean, barely in the DEI. One can obtain a few for deployment from the literature. Mainly, they were operated from Darwin. No fanfare...into oblivion. A wonderful addition for me because I like to include it into a DEI mission or two. Remember...though...just barely. Cheers and prost and great work...
-
...yep...quick reference...out of Darwin along with the P-36A-7. Imagine that.
-
You have a good and interesting choice in topics, Zflyer. Very nice!
-
The SNC-1 skins fit this btw peeps

Great! Nice work, as Dutchman always nice to have another dutch plane in the game. But I have a small problem: When I tried to load this in the game I got a 70% error. I found in both the that CW22B classfile and the CW22Bxyz classfile the line "FlightModels/CW-22.fmd:CW22_FM". So the game start looking for CW22_FM, where the FM files delivered are called CW22B._FM. So you'd have to change the line in at least the CW22B classfile to "FlightModels/CW-22.fmd:CW22B_FM", or remake the FM files nand name them CW22_FM. The first would be the best I Think.
-
Tested the CW22 in a 409modact with the '-409-412fm' provided and the game crashed at 60% loadup.
Here is the last part of the log file:

Hope this can be fixed, it would be a great addition to my South Pacific install.
Note,
forgot to mention that I did try it in my 412modact and the game crashed at
60% loadup('NullPointerException')

The CW22B Falcon was used in Java by the Dutch mainly as a trainer then during the Japanese attack it was pressed into service for recon duties. It was even equipped with a 50kg bomb which it dropped on the invasion forces. Has the model we use in Flashpoint BAT ever had the bomb added?
I ask because Von and I are working on a Dutch campaign and we would like to use the CW22B as part of the defence forces in the bombing mode.
-
Property.set(class1, "FlightModel", "FlightModels/CW-22.fmd:CW22_FM");
CW-22.fmd cannot be read by the game in the CW22B_FM file.
ntrkwizard.jar 2007 and 2013 do not open CW22B_FM file. :-[
------------------------
I put a fix on aviaskins to work in patches 4.09-4.10
-
The CW22B does actually fly in BAT Flashpoint and is flyable. Even the rear gunner works. It does not however have any bombload. I am not sure if the FM is accurate but is probably based on the CW21B fighter. The latter is an equal opponent to the Ki43-1 Oscar.
-
As a temporary solution I have repacked the original FM in a file called CW22_FM as requested by the plane class
I also renamed the FMD that is now called CW-22.fmd as indicated in the plane class and corrected the engine model request accordingly
The flight model is encrypted for 409/412, 410 and HSFX and I tested in 409 modact, 4.12 modact and UP34. The plane flies correctly the only glitch is that in 409 is lacking the Mgun dump hook and therefore the plane can fly only with empty weapons. The plane can fly in BAT-WAW as this plane was already included and has both versions of the FM (CW22_FM and CW22B_FM).

Polara in fm with bugs, very bad bugs. :-X
The CW-21/22 wing profile is very close to NASA 22015/12,
and the polar is written for a modern laminar wing sport aircraft
that will have even more Cy in inverted flight than in the correct position.

I was able to find the thread at Aviaskins and downloaded the FM thank you. However I don't fully understand why in your engine emd the Wright Whirlwind R-975 E3 engine has only 306 Hp when historically it was rated at 450 HP at takeoff and providing at least 420 HP at 1400 ft. Considering also that the engine had a supercharger and could accomodate for a variable pitch airscrew it seems to me that it is a little underpowered with your configuration.

Народи Східної Європи "нечистого" інколи називають мавпою Господа.
Творці CW-21 на жаль назвали словом, яке я не бажав писати, тому використав словосполучення з тим самим змістом.
На жаль англійську мову не знаю, бо в житті не користувався цією мовою, хоча вчив у школі близько 30 років тому.
Нічого поганого не мав бажання писати.
З повагою!)

Sorry! - translated by Google translator.
Here is a Wikipedia link for the word idiom.
https://uk.wikipedia.org/wiki/Ідіома
The peoples of Eastern Europe sometimes call the "unclean" the Lord's monkey.
The creators of CW-21 unfortunately called a word that I did not want to write, so I used a word combination with the same meaning.
Unfortunately, I do not know English, because I have never used this language in my life, although I taught at school about 30 years ago.
There was nothing wrong with wanting to write.
Best regards!

(Скажіть будь-ласка! - у вас є документи що стосуються літака CW-22?
Чи наприклад документ для двигуна Wright R-975-28?
https://www.ebay.com/itm/125740527349
Для того щоб нам вирішити потужність цього двигуна, присутність привідного компрессора -
потрібно мати документи.
Написав ємд двигуна з вікіпедії.
Для більш правильного запису двигуна в ємд потрібні оригінальні документи.
В мене їх немає, тому тут і не давав прямого посилання на мої "виправлення" відносно CW-22.)

Tell me please! - do you have documents related to the CW-22 aircraft?
Is the document for the Wright R-975-28 engine for example?
https://www.ebay.com/itm/125740527349
In order for us to decide the power of this engine, the presence of a drive compressor - we need to have documents.
Wrote the engine emd from Wikipedia.
For a more correct entry of the engine in the EMD, original documents are required. I don't have them, so I didn't give a direct reference to my "corrections" regarding the CW-22.

My documentation on the Wright Whirlwind engine is based on the book Jane's Fighting Aircraft of World War II edition 1946/47. There is a section that is called All the World 's Aero Engine that provide details on the Wright Whirlwind series. For the supercharger states "All models (except the R-760ET) are equipped with a General Electric supercharger geared by the crankshafts. Supercharger drives at seven to ten times crankshaft speed. On the airscrew states that there is provision for hydraulically controllable pitch airscrew. On the engine performance there is a table with 450h.p. at 2250 rpm for take off. 412h.p. at 2200 rpm as normal rating at sea level and 420h.p. at 2200rpm at 1400 ft. (430 m). Compression ratio 6.3:1. Blower ratio 10.15:1. Engine dry weight 306 kg. Fuel 91 Octane.
I will try to post a scan of the page that is not easy as the book is large as usual for the Jane's publications.
-
I'm curious: what problem(s) are you trying to solve with this FM? I ask because as Larschance said, he and I are working with this aircraft in a BAT campaign right now and it seems fine. What are we missing?

I hope that your book contains scans of official documents from Wright Whirlwind.
Because I also have some tables for readers to familiarize themselves with.

An airplane engine does not transmit torque to the wheels like a car does, but a piston aircraft engine turns a propeller that pushes air away,
thereby creating thrust. The thrust capacity of the screw can be estimated if you know its diameter, revolutions and reduction ratio.
So, for the CW-22 aircraft, you need to know which propeller was installed.
I think together we will be able to write a more accurate engine for the CW-22. :)

"I'm curious: what problem(s) are you trying to solve with this FM? I ask because as Larschance said, he and I are working with this aircraft in a BAT campaign right now and it seems fine. What are we missing?"
The original FM has a few problems. On the Flight Model side the polares section seems more adequate for a fighter rather than a scout/trainer plane. I suppose that some parts of the fmd are derived from the CW-21 that is a fighter. The engine model is also problematic as far as performance is concerned 720hp versus a max of 450 in relation to real world data. So it ends up in a plane that is definitely flyable but with an overall performance that seems overrated.
So I think that a little tweaking of the FM is needed but as usual this is not taking out anything from the modders that realized this nice model and nothing against others using and flying the plane as it is
Cheers

Vasya, i tried to scan but as mentioned the book is big and heavy and I am using my mobile phone for the scan so quality is not great. Jane's editions are considered to be a reliable source on Military matters and is normally used a reference. In any case overall the engine performance data that we have is quite similar and be aware that I am considering the R-975-E3 engine

(Дуже дякую!
Скажіть будь-ласка! - чи є у вашій книзі фото двигуна R-975E-3,
на якому я міг би побачити привідний компрессор?
https://drive.google.com/file/d/1sbhGJq4Tb2OxX3IhnlmpP6WkjlfTXgQK/view?usp=share_link
Можливо є посилання на документ, в якому написані дані щодо тиску
який створював компрессор, графік висотності, температурні режими, розхід палива?
Це дуже важливо для правильного написання емд.
Також потрібні дані який гвинт ставили до цього двигуна на літак CW-22.
Як би мій дохід був не 220 долярів на місяць(проживаю у дуже бідній країні),
а вище, то купив би книгу для двигуна R-975E-3, а також інші документи.
Але на жаль фінансові труднощі інколи не дозволяють мені мати потрібні документи, тому користуюся безоплатними.
Якщо ви зможете знайти достовірну технічну інформацію щодо літака CW-22 та його двигуна, то ми зможемо правильно її записати в емд та фмд. )
Thank you very much!
Tell me please! - is there a photo of the R-975E-3 engine in your book,
on which I could see the drive compressor?
Perhaps there is a link to a document in which data is written about the pressure created by the compressor, the altitude graph, temperature regimes, fuel consumption?
This is very important for the correct spelling of emd.
We also need data on which propeller was put on this engine on the CW-22 aircraft.
If my income were not 220 dollars a month (I live in a very poor country), but higher, I would buy a book for the R-975E-3 engine, as well as other documents.
But unfortunately, financial difficulties sometimes do not allow me to have the necessary documents, so I use free ones.
If you can find reliable technical information about the CW-22 aircraft and its engine, then we can correctly record it in emd and fmd.

In the first pic you can see two images of the R-975E-3 engine. On the left side you can see the General Electric compressor that (similar to the one in your pic) and below the compressor the Stromberg Carburetor as mentioned in the text. Considering that the compressor was standard I am quite sure that we can use data from similar engines of that period. For the airscrew we can assume the use of a standard 2-bladed variable-pitch metal propeller as was the case for the SNC-1. Even if approximate these are reasonable estimates. I will continue searching

(Буду чекати від вас документи для двигуна R-975E-3, за якими ми змогли б точно записати в ємд історично правильні характеристики, а не наші фантазії.
І ще: стандартний компрессор для двигунів Wright-Cyclone мав висотність від 1700 до 2900 метрів в залежності від наддува.
Тому для правильного написання двигуна R-975E-3 потрібна фірмова документація, а не книжки для широкого загалу читачів.)
---------------
I will wait for the documents for the R-975E-3 engine from you, according to which we would be able to accurately record historically correct characteristics in the EMD, and not our fantasies.
And one more thing: the standard compressor for Wright-Cyclone engines had an altitude of 1,700 to 2,900 meters, depending on boost.
Therefore, the correct spelling of the R-975E-3 engine requires proprietary documentation, not books for the general public.
