Looks like a BL.10 to me by Gerard Lantrés.

BL10.

Robbed !

Almost right, I'd say; Mugged ! :cool:

Interesting craft - ALL wooden, no canvas. Only 2.4M long. Must have flown like a house brick.

Precision done, and 24 HRS passed - can you declare the winner please...

Gentlemen, you must decide amongst yourselves who is the winner. The identity of the machine in my image is the Bouffort et Lantrès BL.10, which employed the Elytroplan design of the Vicomte Charles de Rougé. For those who read French, you'll find more about it at Charles de Rougé et les Elytroplans, where there is also an article which describes the flight principles of the Elytroplan. For my part, I doubt that I'll have any further involvement with this thread. Sadly the moderation is too heavy handed for my taste. But I wish you good sport in the future. Au revoir.

Fly this...and stay fashionable...

The exact type number will be difficult!

Bear - I'll accept the Country, designer name and what was the massive achievement he created in terms of the aircraft pictured.

Perhaps because you beat Dook in the last round by naming the model number?

By the way, I think you should insist on 2 Countries to be mentioned.

I will accept Country of origin, Designer and mechanical concept that revolutionised FLIGHT.

But for now; Auxtank retires for the night.
Sleep on it chaps - we'll hear ourselves again in't morning.

Possibly the Pescara Model 3 which was the first of several coaxial helicopter designs by Raúl Pateras Pescara to demonstrate sustained controlled helicopter flight

Good shot MReyn,
You got it. Argentinian Marquis de Pateras Pescara produced several Helicopters - this one being Model 3 - that had the contra-rotating 'biplane' rotors.

Honourable mention to dook who nailed the fact that this was the first to successfully demonstrate true cyclic pitch control.

Note the Batman wings over the cockpit to prevent rotor ingress to pilot head in the event of break up.
Bloody brave souls.

Thank you Auxrank. Tracking on that beast would have been a nightmare. Not like the simple days tracking the main rotor on the Bell 47, i.e. broom stick rubber pad and china-graph pencil.

Here is the next:-

Is it just the photo or are those some odd wing tips there?
Fuel tanks?

They are reported to be tip tanks.

They look like c310 tip tanks...is it an early 152/172...?

Sorry for the delay no not an early 152/172

American ?
