!904 - Technical Advancements

In their 1904 Flyer, the Wright Brothers built a new engine similar to the 1903 Flyer engine but with increased horse power by slightly increasing the bore (diameter of the piston). They also built a new airframe which was very similar to the 1903 aFlyer but with redesigned rudders. In an effort to improve pitch, the brothers moved the radiator and fuel tank from the front struts to the rear struts and moved the engine aft to move the aircraft center of gravity aft.
