flight tests revealed remarkably low vibration level as well as good controllability and stability. Therefore, two more prototypes were built, in which the experience gained with the first prototype was taken into account. However, the first prototype was destroyed during tests, and the
Bundeswehr opted for the SE-3130 Alouette II rather than the SM 67 due to the earlier availability of the former.
