Spanning approximately 20 feet, the Spruce Goose designed, built, and flown by Joe Bok and Aero Telemetry for Martin Scorsese's film The Aviator, had a wing that was constructed mainly from wood, just like the original. Spruce and Finnish Birch, were the primary components and balsa was used for the leading edge. 6061-T6 Aluminum was used as the main and secondary spar wing joiner. This amazing Spruce Goose model used 8 electric motors for power. The motors had to small enough to fit entirely inside the scaled down engine cowls, due to filming constraints and scale appearance for the cameras. The Hughes H-4 also featured starboard engines turning clockwise and port-wing engines running counter-clockwise for directional stability during flight and while taxiing.
