The company was founded in 1992 with the goal to manufacture models for the F3x categories. At the same time a partnership with the Robbe company was established, for which we made parts for their production. We took part in the manufacturing of the fuselages for the helicopters Futura, Futura Royal, Zenit, and the F5B model Limit.
