Quite a poor performance was demonstrated. But such an aircraft was badly needed. Production started yet before all tests were performed. As a result service career of the MTB-1 started with the accident - first production aircraft crashed when fabric was torn of the wing. Later another crash took place...
Aircraft was in service for several years as a reconnaissater and torpedo-bomber, but production was very limited. Not a surprise.
