Hello! So we are converting from the actual size into the model. 1 inch of the model represents 40 feet of the airplane. To find how long the model will be, all you have to do is divide the actual length by the model length. In this case, we will divide that by 40, because 40ft represents 1 inch. 211/40 is 5.275. There. The wings of the model will be 5.275 inches.
