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 am quite sure that the FM is derived from the fighter CW-21 should be amended

I put my research on fm 21/22 of the "monkey of the Lord" model on the aviaskins.

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.

Ось посилання на Вікіпедію щодо слова ідіома.

https://drive.google.com/file/d/1UbTHarkFzVuzWI7z4WFdRNDWAMbE7KKN/view?usp=share_link
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.
