"Human-powered helicopters are hard to build"

A team at the University of Maryland are building a human-powered helicopter in an attempt to win the Igor I. Sikorsky Human Powered Helicopter Competition. To win the $250,000 prize, the helicopter must fly for 60 seconds, reach a momentary altitude of 3 meters, and stay within a 10 meter square. This is surprisingly difficult.

I’d call it unsurprisingly difficult!
