The J8 was the prototype for the J.11.
The J8/J10/J11 series were very much just two seat adaptations of the J7/J9 single seat fighters. All derived their origin from the innovative J1 of 1915. They were all metal low wing cantilever monoplanes. Typical for their appearance was the corrugated light duralumin skin and the flat radiator in front of the engine.
