If it were a P-51, then the "B" model. Specifically Captain Bill Overstreet's "Berlin Express" as I had the honor to meet and fly with him, an RC model airplane, before he died in 2013. He was, as I am, a member of a local flying club in Roanoke, Virginia, United States. The airplane was a Hobbico Playmate...
A far--- FAR cry from the Mustang Capt. Overstreet flew under the Eiffel Tower during WWII in pursuit of a 109.
