The F.XI was a feeder liner and air taxi, and was similar to the American Universal in appearance. However, it was definitely not the same aircraft. The Universal was designed in America by Noordwyn; the F. XI in Holland. The aircraft could carry four to six passengers and two pilots. Three aircraft of this type were built, two going to the Hungarian Company Malert, and the third to the Swiss Company Alpar.
