Collapsible & Portable Helicopter
This portable one man helicopter is designed to be collapsed into a compact unit
for easy transportation, and can be completely assembled in the field, ready to fly in a hurry. Simple snap out pins are used to connect the components in a typical
joint in the base of the helicopter. It weighs less than 250 pounds, and can be assembled within less than 10 minutes. It is powered by a 45-hp four cylinder
two-cycle engine, with a top speed of 60 mph. Drawings and instructions.
