> Our human-engine will produce only 1 horsepower
I thought an Olympic athlete at full-tilt with arms and legs could only put out 0.75 horsepower?

"At 772 Watts for 1 minute, our pilot’s power output exceeds the power requirements of the helicopter by a safe margin."
From: http://www.aerovelo.com/projects/helicopter/tech-info/
"a healthy human can produce about 1.2 hp briefly and sustain about 0.1 hp indefinitely; trained athletes can manage up to about 2.5 hp briefly and 0.3 hp for a period of several hours."
And for those who wonder how a human can be stronger than a horse: peak output of a horse is way higher than 1 hp ("The peak power over a few seconds has been measured to be as high as 14.9 hp.")

One HP is 750 Watts, which looks like roughly 20-30 seconds of endurance for a 'first class athlete', which should be enough time for this.
The best track sprinters are in the 2000w for several seconds range.
