New Sparrow Drive Design
The original 300 Sparrows were propelled by a DC (Direct Current) motor. These drives were very reliable and offered operating longevity. The Sparrow II will be driven by a 3 phase AC (Alternating Current) motor. This new drive offers the highest form of electric motor configuration and efficiency with 35 peak hp and 10 hp continuous duty.
To develop and test the AC system, Mike's original Sparrow #100 is being retrofitted to the AC motor. With our newly revamped machine shop capable of complex billet components Vince and Armando designed a motor mount and swingarm assembly to hang the new powerplant. With more carefully designed aluminum components like this we hope to remove gross vehicle weight from Sparrow II.
Keep your eye on the Sparrow, the best flights are yet to be launched.
