PIK Pik-11 Tumppu
PIK has also built several low-wing single-engine monoplanes, including the Pik-11 in 1953.
The PIK-11 Tumppu is a single seat, sports aircraft, capable of aerobatics. It was designed in the 1950’s by two students and members of the student flying club of the Helsinki University of Technology (PIK or Polyteknikkojen Ilmailukerho), Kai Mellén and Ilkka Lounamaa.
Four aircraft of this type were built, one of which was still in operation in 2006.
