A machine designed to move a pair of light weight graphite fiber composite covered wings in such a way that their tips will describe a horizontal figure eight through the air. Thereby sustaining an attack angle and creating lift throughout as much as 80% of their travel path. The mechanism retains 100% control over the wing movement and with a locking device in place the preferred embodiment should be capable of a good glide ratio.

A mechanical wing drive to propel a flying machine comprising: a center shaft extending from the base of each of a pair of wings and extending through one of a pair of oarlock devices, each said oarlock device attached to one of two parallel main frame members, the end of each said center shaft connected by a universal joint to a common plate mounted on top of a linear ball bearing, said linear ball bearing riding on a shaft held by a bracket on each end of said shaft, said shaft connected to a pivoting mount supported between said main frame members, also on said main frame members, beyond said overlock devices, are two raised crankshaft bearing supports which hold a crankshaft, said crankshaft creating back and forth motion of said center shafts, said crankshaft extending across said main frame members, said linear ball bearing running parallel with and between said main frame members, a connecting rod attached on one end to a throw on said crankshaft and on its other end to said common plate, also on said crankshaft is an intermittent motion cam track, synchronized with said throw, and connected by a cam follower to a cam follower rocker for creating up-down motion of said center shafts, said cam follower rocker connected to said bracket on said shaft end closest to said crankshaft, also on said crankshaft is a drive chain sprocket connected by a drive chain to a drive motor, wherein said crankshaft and said intermittent motion cam track cooperate to create a “figure 8”motion of said center shaft extending from each wing.
