In 1925, Bellanca went to work for the Wright Aeronautical Corporation of Paterson, NJ. His assignment there was to develop an aircraft around the new Wright Whirlwind engine. He already had a design in mind, which was an improved version of the CF, called the CG. This design evolved into the Wright-Bellanca WB-1.
The WB-1 enjoyed a short, but successful flying career. The aircraft had already won one race and efficiency contest before an untimely accident destroyed the craft during preparation for an attempt to break the world's non-refueled endurance record. Fortunately, at the time of the crash, Bellanca was already working on an improved version, of the WB-1 designated the WB-2.
