A Jetcopter is a helicopter with jet engines. They can be flown like normal helicopters at up to 50 kph. Using the jet engines allows them to fly at speeds up to 350 kph. Jetcopters can increase or decrease their altitude by 20 meters a turn. When scouting, jetcopters fly at or above the level of the treetops, 50 to 100 meters above the ground. To stay out of sight they can fly very close to the ground, following the contours of the hills and valleys. This is called Nap of the Earth (NOE) flying. NOE flying limits an jetcopter to 100 kph (175 meters/turn).
