Several reports and lectures on the history of the FVA has remained unclear which project FVA-12 was assigned.
The author of the memorial volume "60 years of FVA" could get only on the basis about it from extensive interviews with former members and from various information. It can be assumed with near certainty that the FVA-12 had been a design for a lightweight powered aircraft as part of a thesis. Bruno Sann and Felix Kracht still remember very well that the plan to build such a power plane in the 1937/38 period was discussed in the FVA, but soon fell into disuse because of the pressure of time for project FVA-13.
It was not possible to determine who was involved in the construction of the FVA-12, in any case it was never built.
