First
Research begins at University of California, Berkely through out a $2.5billion contract. -
Then
The prototype with a single wing showed thrust forces on a test stand. -
Next
Fabrication was switched from folded stainless steel to carbon fiber. -
After That
500 microNewtons of lift from a single wing was demostrated on a test stand. -
Finally
To current-Work concentrated on reducing weight, increasing actuator power density, increasing air frame strength, and improving wing control.
