Ken. If you really want that information I could give you a copy of the spreadsheet and you could work it out in no time.

Well it is the Asboth AH-4 but it's from Hungary.
I'll give to you anyway.![Wink](https://www.pprune.org/images/smilies/wink2.gif)

Hungarian engineer Oscar von Asboth, who had worked on the two PKZ machines, designed and tested four different helicopters between 1928 and 1931.
His final machine, the AH-4 used counter-rotating coaxial main rotors powered by a 110hp Clerget rotary engine with multiple hinged vanes in the rotor downwash. Control was very poor, but by mid-1930 the aircraft reportedly attained an altitude of 30m and covered 3.2km at about 19km/h.

Now that you are back with us for a few mins then at least you can put some effort into coming up with some more interesting stats. So your task is:

All very quiet so a clue. Aircraft first flew in the late 1930's and flew with a variety of different engines, including a Britsh one (the aircraft itself is not British), Designed for endurance flight training.
That'll be it LM and I take pride in the fact that it worked
Is that the subtelty which you mentioned to Mel, Ken?

Evening all!
Good to see you're back LM!![Thumb](https://www.pprune.org/images/smilies/thumbs.gif)
since
and since the engine portrayed in the silhouette is, as far as I can see, a horizontally opposed one, am I wrong in assuming we're talking about a Bristol Cherub?
Good to see you're back LM!

the silhouette features the English engine - a Bristol design

Supper now.
German? Anything to do with Arado, Messerschmitt or Blume?
Really can't find anything with google... it's really a challenge, this challenge of yours!
When I'm back I'm perhaps going to look into Ferriere's 3-vues, just in case...

HappyPass, not German (head east!) and you won't find in Ferriere's 3-views.
Some further info - believe first flown 1939. Designed to have endurance in excess of 20 hours, but due to lack of a suitable engine it seems that was never achieved.
