Make Your Own Gadget: From Idea To Reality

Overhaul: Taking the Prototype to a New Level

In addition to an interest in flight, William also has a knack for 3D animation and computer-aided design, which he used to redesign and create a brand-new chassis for his Shrediquette. He used carbon fiber-coated plywood and tubing to save weight, which also made the design look a lot better overall. By reducing the overall weight, he increased its responsiveness, and therefore, its stability, but that was just the start of the overhaul.

William still felt that his design could be more stable. He replaced his cheap motors with more expensive and significantly more powerful motors, which greatly improved responsiveness. He also upgraded his gyros by adding more accurate models and modified the throttle response.

All together, the upgrades made the Shrediquette extremely stable. It was so stable in fact, that William decided to add profile settings to his control loop. The first mode, which he calls "hover mode," is intended for enhanced stability and is ideal for carrying heavy or unstable payloads. "Acro mode" switches the controller from keeping the craft level to instead keeping angular velocities smooth and constant, allowing for aerial acrobatics like loops and rolls.

    DAMN i hope he patents this thing,,, hes just invented something the US air force has been trying to do for years! -- fast , highly mobile helicopters with excellent hovering capabilities.

    He could patent it, but I think he's more interested in the concept of free exchange. You can pretty much find all of the information you'd need, including blueprints and source codes to build your own tri-copter right on his blog.

    Real something, not easy part to balance and stabilise whole thing. My hat! I will love to gev it a try my self. Using William's article as starting point...
    A new hobby is born?
    :P)
