Not a boat and not a German! Witness the diversity!
This is a replica of the Soviet experimental super-light fighter that never saw the light of official testing due to its inability to carry ACs (or the fact that the final call was made by the head of a rival design Bureau, we'll never know), it carried the most rapidfire single-barreled machineguns though and rumored to be really fast, alas, we'll never know for sure also.
The bot turned out to be very light and nice to fly. Check it out at the factory, tag: [whr].
