According to aerospace publication Flight International, the adaption from the earlier Fleuret to the Paris had been largely achieved via the elimination of the former's armament, the re-design of the cabin floor to remove the downward ejection hatch arrangement, and the repositioning of the cabin's rear bulkhead slightly aft. To avoid a reduction of the aircraft's available fuel tankage as a result of the latter change, the tank was re-profiled in other areas to expand it. In spite of these changes, the Paris still retained the favourable flying characteristics and did not entirely foreclose its use as a trainer aircraft.
