From fighting deadly forest fires to rescuing troops behind enemy lines, helicopters perform incredible feats. Filled with exciting illustrations, easy instructions, and fascinating tidbits on all types of helicopters and their uses, Flight Test Lab: Helicopters explains concepts like flight theory; describes the latest technology; and explores the inner workings of these mechanical marvels. Author Paul Beck describes Thomas Edison's near-deadly attempts at helicopter design and explains how Black Hawks can fly over 1,100 miles. Best of all is the inclusion of all the parts — even a launcher — needed to assemble a simple flying helicopter, a police copter, a military chopper, and a rescue helicopter.
