Tom Stanton’s Hand-Cranked Plane Soars After Mere Seconds of Effort

Tom Stanton has spent years fiddling with many strange flying machines. His current idea cleverly updates a traditional toy. Rubber band planes have been around forever, storing energy in twisted bands that then spin a propeller. The problem is that they must be wound up for several minutes merely to produce a short burst of flight. Stanton sought to create a flying machine that was faster, more practical, and could be built with easily accessible components.

Instead of relying on rubber bands, Stanton used supercapacitors to store energy. A hand crank generator charges the capacitors up to a 10-farad unit, which weighs just 3 grams and takes just a few seconds to charge. To keep an eye on things, an analog voltmeter is used to ensure that the voltage does not exceed 2.7 volts and destroy the capacitor. Once fully charged, the capacitor powers a small brushed motor repurposed from a toy drone, which propels a propeller engineered to work efficiently with the capacitor’s low voltages.

Stanton just printed the wings directly onto tissue paper. He used a textured construction plate secured with magnets so that the printer could lay down the structure without breaking the paper. After finishing the print, he simply clipped the edges, applied some adhesive, and used a heat gun to mold the paper so it could function as an airfoil. The initial effort at a wing was a disaster, as it flexed too much under load, sending the plane straight into the ground. However, later versions converted to shorter wings with a greater aspect ratio, which solved the problem by reducing flex and drag while adding minimal weight.

The plane’s fuselage is built of carbon fiber rods, which provide it strength without weighing a ton. Stanton built notches into the rod to prevent it from being drilled out of the holes, allowing the wings and tail to slip in and out with a simple friction fit, making changes easy when testing the plane. The tail is a 3D print that is glued to the back of the rod, and up front, a small steel bolt serves as the nose weight to keep everything balanced. Stanton adjusted the wing mount slightly to keep the propeller out of the line of the airflow, and a printed bracket connects the capacitor and motor and simply clips into the rod.

First, Stanton tested the basic glider on its own, as it was so light (weighing only 3.8 grams) that it flew through the air like a dream and outperformed a simple paper plane. Adding the power system increased the total weight to 15.6 grams, which isn’t terrible given it’s still lighter per square inch than most paper airplanes. When he tried it with the power system, it shot up high after launch and settled into a long, steady glide. Cranking the hand crank for 4 seconds gave him 45 seconds of flight time, but what about the charging time? It was a blazing 0.1 seconds. Stanton thought the charging-to-flight time ratio was impressive to say the least, especially since the charging process takes roughly the same amount of time as blinking.

Cold and damp air reveal one weakness: tissue paper absorbs moisture and loses rigidity quickly. The wings began to sag and the plane fought to stay aloft, as Stanton mentioned in his video, although other individuals have had success with minor repairs such as coatings on comparable planes. To be fair, the primary design of the product demonstrated that the concept works. In the end, the last plane popped right up off the ground, kept altitude far longer than I expected, and then glided down for a rather easy landing.

Stanton made the glider files accessible on Printables, allowing anyone to print their own version and try it out. The entire project is very simple, as it just requires some basic hardware: a 3D printer, a piece of tissue paper, a carbon rod, and the minimum essentials of some electronics. There are no sophisticated or high-tech materials or intricate machine work involved.
