The stall was slow and preceded by vibrations. The plane also turned out to be easily maneuvered with one engine shut down, which at the time was typically not the case with twin-engined aircraft. Unfortunately the rudder harmony was not satisfactory, with high control forces in some situations.
The stall was slow and accompanied by vibrations. It turned out that the plane could be maneuvered quite easily even when one engine was shut down; this was uncommon for twin-engine planes at the time. However, the rudder coordination wasn't satisfactory, requiring substantial control efforts under some conditions.
