Inside a Ducted Fan UAV

Trek Areospace's

OVIWUN UAV uses twin counter-rotating ducted fans built of
lightweight materials, dual 450-watt electric motors,
a high-efficiency drive train, 14 volt rechargeable battery power
system, 3-axis gyro, a low-power PC104-based
processor, and open-source flight control software. The vehicle is
about 14" tall, weighs a tad over 6 pounds, and is capable of 40+
mph with a maximum hover ceiling of more than 3 miles. Typical battery
life is about 20 minutes. It's amazing that $15k can now buy a UAV that
would have costs millions only a decade ago.
