There’s an open-source airplane being developed in Canada, and now its designers are looking to double down on the digital trends, turning to crowdsourced funding to finish the project.
The goal of Maker Plane is to develop a small, two-seat airplane that qualifies as a light sport aircraft and is affordable, safe, and easy to fly. But unlike other home-built aircraft, where companies or individuals charge for their plans or kits, Maker Plane will give its design away for free.
The group behind the project consists of pilots and engineers who are designing the airplane, allowing it to be built using the kind of personal manufacturing equipment somebody in the maker community might already have at home or can easily purchase. The idea of a home-built airplane is nothing new. It dates back to the earliest days of flight, after Orville and Wilbur made and flew their own airplanes (and engine), the homemade plane movement — literally — took off.
Today, the home-built movement continues, and this week tens of thousands of pilots and fans of home-built airplanes are descending on the annual Airventure in Oshkosh, Wisconsin.

In the spirit of the open source and maker movements, the Maker Plane group is including components from many designers and builders outside their circle. As they focus on the design of the airplane (fuselage, wings, etc.), the Maker Plane team helps connect those interested in building their own with other open source components such as an air data computer and radios. They even show you where you can get plans to build your own traffic and collision avoidance system.
The structural parts of the airplane, including the fuselage, will be built from composites. There are many home-built composite airplanes already taking to the skies, so the techniques are well proven. Smaller pieces such as knobs and handles will be made using 3-D printing. And after a year and a half of design, the Maker Plane team has started to build the first prototype. That’s why they’re turning tocrowdsourced funding to help the project along.
The basic specifications of the airplane follow the guidelines of the light sport aircraft regulations. The aviation industry and the Federal Aviation Administration created the LSA category to encourage more people to fly. The airplanes are limited to two seats, a maximum weight of 1,320 pounds, and a top speed of 120 knots (138 mph).
Maker Plane says they expect their design will fall within these requirements and have a range of 400 miles. More ambitious: They hope the cost to build the airplane will be under $15,000, including the engine.
The aviation world is filled with optimistic ideas that don’t always get off the ground, but the Maker Plane is the first attempt at sourcing the entire airplane from the open-source community, which should help keep costs down, assuming you have the skills to build the various components. And if they succeed, Maker Plane hopes to fly the first prototype in 2015.
