First appearing in 1931, the S.66 prototype was a larger development of the S.55 accommodating 14 passengers and powered by three A.22R engines. Production aircraft were fitted with 522kW Fiat A.24R engines, raising accommodation to 18. S.66s entered commercial service and at least one was taken on charge by the Regia Aeronautica.

After using three view drawings and a CAD program we are nearing compleation of an 18ft RC model of the SM66. However,we find we have a rather drastic CG condition. Can you offer any a help in arriving at the correct wing root chord due to the intervening hulls? Any assistance you might give us would be greatly appreciated.
