As I said, an easy one...

Vought 326, seen here with the R-4360 engine.

Check the 2 pictures again. They have a completely different engine cowling. The second picture is probably a very early version with a smaller engine.

One may be the V-326 and the other the V-326A.

It was originally built to test the R-4360 but flew with different engines at a later stage.

It is Theo Slot's delightful little one man flying boat, the De Schelde Scheldemeeuw.

Addendum: I thought we'd had the Scheldemeuuw recently and when I checked we did, back in March (q.v. post #1107)

I should have checked but didn't. You got it fauteuil volant, over to you.

Thank you, teusje. As I shall be occupied today, it's best I declare open house. If that invitation has not been taken up by this evening, I'll try to find a next challenge then.

@ Archer, the size of the propeller suggests an large horsepower, therefore the small diameter is striking in my view. The other version with the large diameter engine is of course totally different, I agree.

The R4360 has four rows of seven cylinders, the R2800 on the original Corsair which I assume powered the original version, has two rows of nine, so a slimmer package on the more powerful engine seems likely. The F2G Corsair with the the R4360 is very similar to the F4U at the front, while the V-326 installation looks almost like the Dart on the HS748 and G1 or the several Dart P-51s that appeared briefly around 1970.

Never heard of the V-326, nor, as far as I can see, has Wikipedia! Good educational thread this...

The R4360 and R2800 would have been similar in overall diameter - reducing the number of cylinders/row would make little difference and the cylinder heads were different.
Secondly, I think you may be confusing the abbreviation DaveReidUK used for the aeroplane (Vought 326) with the US terminology for the engines (e.g. V1710).

I think the difference in diameter of the engine is not as great as the difference in the cowling. The V-326 (with the R2800) has a big chin inlet; the V-326A (with the R4360, and I hope I've got that the right way round) does not have that lower inlet. A quick eyeballing of diameter of front of cowling against wheel size suggests they are not as different as they at first appear, allowing for that difference, and of course the V-326A cowling is a lot longer, which enhances the appearance of slimness. Anybody fancy a bit of photogrammetry?

Certainly surprised that the diameters would be similar - would have thought another couple of pots per row would make quite difference! The only time I've seen either engine close up out of an airframe was a part-sectioned R-4360 at a museum in the US. I was quite surprised how relatively small it seemed compared with what I'd imagined!

Sorry, I meant to refer to the V-326 in the same way as Dave, as the aircraft type.

There's a photo in the gallery on this page: V-326 and V-326A that shows the R-2800 powered one (the VS-326 as far as I can tell) from the front, allowing a comparison with the R-4360 powered VS-326A.


R-4360 engine... a lot of moving parts in a pretty compact format. I shudder to think of having to change the spark plugs on one of them, a C-97 uses four....

Interesting discussion but back to the core purpose of this thread. No-one having taken up my open house offer and being back at my desk again, I'll take matters forward with a neat little parasol wing monoplane.

Having regard to its history, one might describe this as a 'stealth' monoplane!

Hull's finest? Designed, built and flown by a dirt track rider nicknamed 'Nippy'!
