About: I am someone who mass produces paper airplanes and am always developing new designs. I post regular updates on Twitter. Follow me there to keep up with the latest developments!

The Omniwing Zeta (or simply Zeta) is a refined variant of the popular Advanced Omniwing flying wing paper airplane by menamiketrx of YouTube, meant to be fast, long range and stealthy. While the Zeta does retain a good portion of its predecessor's features, it also integrates new building techniques that enable easier construction and better performance.

Development

Development of the Zeta began after I revisited the Advanced Omniwing in November 2015. As it had been some time since I'd last made an Advanced Omniwing, I had forgotten just how much imprecision there was in the design during construction. Knowing that approximation can sometimes lead to problems if certain things are not estimated correctly, I decided to redesign the aircraft to standardize construction. In addition, because of previous experiences with the Advanced Omniwings, I decided I would also integrate vertical stabilizers into the design to improve stability. As I had previously found that six vertical stabilizers provided sufficient yaw stability on unmodified Advanced Omniwings, I believed that this number would be sufficient for the Zeta as well. With these two construction goals in mind, I began prototype work on "the Zeta project."

The first Zeta prototype ("YF3-6A") was made by myself over several hours' time with design decisions made as production progressed. Its general layout was very much like that of an unmodified Advanced Omniwing but its internal structural design became substantially different. Unlike the standard Advanced Omniwing, the Zeta's longerons and spars are one modular assembly composed of several standardized parts, secured into the airframe at key points. This design change offered the advantage of enabling easier construction by allowing individual parts for these structures to be made and handled separately for a long period of time before being put together and then fitted to the wings in a larger group. Eventually, I modified the internal structures of the design to give it better strength with only a very meager amount of weight being added. The design with those modifications excelled and was approved for publication as the F3-6C.
