DR-1 Triplane Technical Specifications
The basic structures use conventional “modeling” tools and materials such as balsa and plywood, and the techniques are straightforward; easily accomplished by anyone with previous model building experience. Building notes are on the plans. The FOKKER DR-1 plan set consists of four large sheets that clearly illustrate all structure as well as showing installation of scale working landing gear and hinges and control horns.
