How to Build Your Own Bensen Gyrocopter: A Step-by-Step Guide (PDF)
If you are looking for a fun and affordable way to experience the thrill of flying, you might want to consider building your own Bensen gyrocopter. A gyrocopter, also known as a gyroplane or autogyro, is a type of aircraft that uses a free-spinning rotor to provide lift and a propeller to provide thrust. Unlike a helicopter, a gyrocopter does not need a tail rotor or a complex transmission system. A gyrocopter can take off and land in short distances, fly at low speeds and altitudes, and maneuver easily in different weather conditions.
One of the most popular and simple designs for a gyrocopter is the Bensen B-8, created by Igor Bensen in 1954. The Bensen B-8 is a single-seat, open-frame gyrocopter that can be built from a kit or from scratch using a set of plans. The Bensen B-8 has a tubular aluminum frame, a plywood fin and rudder, and a wooden rotor blade. The engine can be a flat-four McCulloch 4318 or a 1600cc Volkswagen engine mounted on the mast behind the pilot. The Bensen B-8 can also be modified to have floats, skis, or a second seat.
If you are interested in building your own Bensen gyrocopter, you will need to obtain the plans, the materials, the tools, and the skills to assemble and operate it. You will also need to follow the safety regulations and requirements for experimental aircraft in your country. In this article, we will provide you with a step-by-step guide on how to build your own Bensen gyrocopter using the PDF plans that you can download from our website.

Step 2: Gather the Materials
The next step is to gather the materials that you will need to build your own Bensen gyrocopter. The materials include:
Tubular aluminum for the frame
Plywood for the fin and rudder
Laminated wood for the rotor blade
Metal fittings and hardware for the joints and connections
A flat-four McCulloch 4318 or a 1600cc Volkswagen engine for the power source
A propeller for the thrust
A seat, harness, instruments, controls, and other accessories for the cockpit
Paint, decals, and other finishing touches for the appearance
You can buy some of these materials from specialized suppliers or online stores, or you can salvage them from other sources such as old cars, boats, or planes. You can also customize some of these materials according to your preferences and budget.
Step 3: Assemble the Frame
The third step is to assemble the frame of your Bensen gyrocopter. The frame consists of four main parts: the keel tube, the mast tube, the landing gear, and the tail boom. You will need to cut, bend, drill, and weld the tubular aluminum pieces according to the dimensions and angles shown in the plans. You will also need to attach some metal fittings and hardware such as brackets, bolts, nuts, washers, clamps, hinges, etc.
The keel tube is the main backbone of the frame that runs from the nose to the tail of the gyrocopter. The mast tube is the vertical c481cea774
