The Dunakeszi workshops of the MRSz were not capable of producing the light alloy structure of the OE-1, as designed, so an all wooden wing was built using traditional methods.
[1] The OE-1 was a cantilever mid-wing monoplane built entirely of wood with plywood skinning on structural parts and aircraft fabric covering on control surfaces.
Maximum thickness was moved back to 45% chord to achieve laminar flow, checked in the wind tunnel of the Technical University of Budapest.
[2] V-tail surfaces were carried at the end of the tail-boom at an angle of 114° to each other with push rods operating the large horn balanced ruddervators for yaw control as well as pitch.
