I would guess the wing span on this model to be around 6 feet or more

The B-17 is 1/10 scale and spans just over 10 feet, and was built between 1988 and ’93. It was powered by four Saito .45 Four Strokes and weighed 36 pounds at take off. It was later stripped of the engines and radio and I donated it to the museum for display around 1995 as I had built a larger 1/6 scale version to replace it on the show circuit.

This is the 1/6 scale version in 2004.
