Description The giant scale Beech D-18/C-45 plan set is 1/5 scale and consists of four large sheets that clearly illustrate all structure as well as showing installation of flaps and retracts. The D-18/C-45 plan shows the installation of Robart retracts, fixed wire gear, servos and Zenoah G-38 engines and features three-piece wing. 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.
