Ranger 21 was designed in 1957 by Carl Goldberg and produced as a kit until the late 1970’s. It was intended to help new modelers achieve success in building model airplanes that also flew well. The BMJR kit, designed by Paul Bradley, is a replica of the original. Model is of all sheet balsa construction and has a 21” span with 76 sq. in of area.
Ranger 28, Also designed in 1957 by Carl Goldberg has a 28” wing span and 102 sq. in of wing area. This model is a hybrid with features of the sheet balsa models of the time, with tissue covered built up structure. The fuselage is assembled from laser cut parts much like a jigsaw puzzle, that then gets tissue covered. This was a great model to introduce modelers to the world of a tissue covered built up structure.
