When I saw it I thought "Fike", but now that I've looked at it some more, I don't believe that any more!
Don't know what it is.

I was referring to your description - which I 'm sure is absolutely correct - it just doesn't mean anything to me :ooh:..... but then I don't think I've ever looked under the bonnet of my car in 10 years

As for English design ... a country that produced the Bagshot, the Gannet, the Tabor , the Pterodactyl or the Wellesley etc is in no place to throw aesthetic stones IMHO!!

However as you are probably correct one stands onteh shoulders of Giants and commences a searche for early Rotax 2 cylinder efforts and finds quite a few

It may be the Green Sky Adventure Micro Mong of some variety Several of those have a very similar inlet location and shape

looks liek there's only one picture of the challenge?

American?

American, yes.
Designed for simple construction with no compound curves, no flaps.

I thought the Wittman as well, but it never quite matched.

There are a few out there. Jane's predominately showed it with the wing folded.

good in a cross wind!

NASA did once test a 'slewed wing' aircraft called the AD-1.
Apparently it had some 'unpleasant' handling characteristics.

Noyade's turn again.

​​​​​​​and flying under narrow bridges

Open House please. :ok:

Was this a 'flat-plate drag' experiment?

Russian?

I can see why you might think that chevvron, but not Russian.

I was thinking maybe Russian designed but not Russian built; Sikorsky S22 types?

Not a Sikorsky design nor a Russian designer, as far as I know.

Caproni built some weird looking front ends................

Is it a biplane?

`Academy Windows`(East Anglia) do bay windows like that......
