In response to the message by "Aero-Fox", "the lack of which doomed this little number to severe instability...", the ARUP designs were very succesful and safe aircraft that just did not catch on like other aircraft of the time. The oversized props mentioned on the Chance-Vought were a method to counter vortices off the wingtips to reduce drag and provide more lift to the airfoil. The ARUP aircraft were so safe that there was never a fatality. It flew accident free for many years. This safety record was for the ARUP specific aircraft only. With a 37hp engine, the ARUP could fly 97mph and land at just 23mph. See YouTube for a video on this aircraft. http://www.youtube.com/watch?v=Nxz1UF67EQI

Arup was designed and built by a doctor in South Bend IN in the 1930's and was taken to an air meet in chicago. It was an early lifting body design.
A full size replica has been built and is on display at the South Bend Regional Airport.

Almost looks like a predecessor to the Chance-Vought V-173 'Flying Flapjack', minus the oversized wingtip props...the lack of which probably doomed this little number to severe instability...
