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.
