AIRCRAFT HISTORY exclusively one X04U-1 was built for the NAVY and first flew in 1931. It was Voughts first airplane with a monocoque fuselage and fabric covered metal wing structure. It could be mounted on wheels or floats. It crashed during flight test prior to Navy acceptance. Its intended purpose was as a scouting and observation aircraft. It never made it into production but the seaplane version was planed. Thank you for downloading my aircraft, I hope you enjoy flying it as much as I did building it. chrisherring43_at_ms n. com I welcome any comments or sugestions on this aircraft or any other I have submitted to this site.
