Stroop “X-Wing” Convertible Speed Planes for the USAAC (1935-9)

[jzichek]

A new post is up at RetroMechanix.com presenting the Robert C. Stroop SP-6 and SP-7 "Speed Plane" projects of 1935-9:



These were a pair of designs submitted to the US Army Air Corps which featured a folding scissor "X-wing" to convert the aircraft from biplane to monoplane configuration, the intention being to combine the short field length and climb capabilities of the former with the speed of the latter. The article features 10 images reproducing rare correspondence, drawings, and photos relating to these unusual and innovative projects.

Very different and could definately lend itself to whiffery.  Another design I was never aware of, thanks for posting Jared!

Vostoc7 will have one of those built, and painted gold of course, before tea-time!

One of those, but as a Spitfire, P-51, Meteor...

The Russians had at least one prototype that converted from biplane to monoplane (I've got the A Model kit) but it's not of that X wing configeration. Really interesting

Nikitin Shevchenko IS-1, wings had a double fold into recesses in the fuselage and wing root.

Something with an open cockpit would be cool. Otherwise it could resemble the Sorceress racing biplane...

That's the one Mossie 

That racer looks good pertime
