In the Trait d'Union #217 (Sept-Oct 2004) : "Jean M. Lado-Borkowsky presented in 1936 a new concept: the Helicoplan, to decrease the take-off/landing speeds, or at unchanged speed to increase take-off maximum weight. It uses 2 lifting propellers (rotors?) under the wing at a distance, while the wing stays the main lifting device, during normal flight only the wing is used. The inventor demonstrated that the lifting propellers should be aft of the wing."
On the picture: I is 4-engine flyingboat total 2,800hp. II is 2-engine twin-fuselage plane total 700hp. III is 2-engine twin-boom total 500hp. All of them are monoplanes, II & III seem to have horizontal pylons for the solidity.
