That was my original point.

I read it as trying to say the opposite. Never mind.

The initial prototyp flew with a BMW 139 18 cylinder enginge. The initial wing was 161 square feet in area.

Ah, another "fact" in Greens books proven to be wrong but still living today. The BMW 139 was a 41.2 liter 14-cylinder engine.

Yes the number of cylinders could be a typo.

But are you disputing the relevant fact that the wing area was increased by about 30 square feet?

It doesn't matter, because it was a pre-production prototype. We've agreed (so far) that the wing size between the A3/A4/A5 (up to the Doras) didn't change.

[MiloMorai]

The V5 got the bigger wing, so therefor from the A-0.

For a good book on the 190 read Focke-Wulf Fw190A by Hermann/Leverenz/Weber

IIRC there were several A-0s with smaller wing and I think I have seen pictures of some smaller wing A-0s in a training unit somewhere in France (along with one of the Bf 109F protos).

[Denniss]

There were actually two V5, V5k with the small wing and V5g with the larger wing. Several of these early prototypes had the small wing but most of the A-0 had the larger wing.

I read somewhere in a book that it was ordered to upgrade the small-wing aircraft to the larger wing.

[gripen]

There seem to seven A-0s with the small wing in the Bookie's listing.

Apparently there was just one V5, it just initially got the small wing and later the larger one after an accident.

Seem so, this certainly does not look like a 18 cylinder engine:

Although this is also claimed: "Differences between the 139 and the new design were fairly minor and limited primarily to details except for the use of 14 larger cylinders instead of 18 smaller ones."

I have a question.

How much horsepower is AH 190A-8 really making?  I saw quotes such as "1,800 hp" to "2,050 hp"  If the 190A-8 is 2,050 hp why is it SLOWER and climbs worse than 190A_5:noid

[Krusty]

It climbs worse because it's heavier. It might be slower because it's draggier (must be the extra weight, as the only major difference is the cowling bulges)
