The successful 188 Agwagon agricultural aircraft were Cessna's only purpose designed agplanes. Cessna's Model 188 resulted from extensive research and consultation with agricultural aircraft operators conducted in the early 1960s. The design Cessna settled upon was of the conventional agricultural aircraft arrangement with a braced low wing (unique among Cessna singles) with seating for the pilot only. Like other ag aircraft the chemical hopper is of fibreglass and the rear fuselage is of semi monocoque construction and sealed to reduce the potential for damage from chemical contamination. Mahogany wood. Scale: 1/32. Wingspan 16 1/2 inches, Length 18 1/2 inches.
