Alright, let's see if we can get something interesting...... This one's a bit obscure, so I'll give as much info as I can without totally handing it to you.
This was a British aircraft, first flown in 1928. It was fitted with three Rolls-Royce Condor II engines, but probably should have been fitted with four, as it was extremely underpowered.
There were a few notable characteristics about this aircraft. First were the extreme-high-aspect ratio wings, second being two mainwheels each almost seven feet in diameter. But the most interesting thing was its construction, which employed a method which, at that time, was completely revolutionary.
Only one of these aircraft were build, but it's unfair to call it a prototype, as it was never intended to serve any role, be it bomber, transport, or likewise. It was simply a test-bed for this new construction method. Performance history was nothing to write home about, although it did fly at the 1928 Hendon RAF display bearing a large number 9, used for identification.
It was dismantled in 1930 and the airframe was used to test corrosion.
Finally, and Here's the Kicker:
Despite it's name, the airplane flexed quite a bit.
There. Hopefully it's not too easy!
