Washington (UP) –
The first production model of the new Vought-Sikorsky F4U-1 Navy fighter plane will take to the air Monday.
The plane will have a demonstration flight at the Stratford, Conn., plant of the Vought-Sikorsky Aircraft Division.
The Navy did not reveal any details concerning the plane’s performance. The new fighter, which has been named the “Corsair”, is an inverted gull wing model.
Inverted gull wings? Sounds like a dud, this plane will probably be dumped on some Black Sheep squadron 
Oh, you’ll see what happens in a while… 
Can’t be any worse than that underpowered p51. What a waste of aircraft money.
P51 as in the Mustang?
Yes. The original Mustang powered by an Allison engine was not considered a great performer and had just reached service in January of 1942. It wasn’t until they put the Merlin engine in that it could outperform the German fighters. Later the P51-D had another engine upgrade still.
Zero to (Mig) 15 killer. Legendary aircraft and one of the first models I built
