Multirotor drones tend to need quality and well-matched parts in order to stay balanced and in the air. However, crash enough drones and you might find you’ve got plenty of mistmatched bits and pieces lying around. In just this vein, [Jason Suter] decided to raid his junk box and built himself a little FPV airboat using spare parts.
The airboat consists of a 3D printed hull, paired with a separate power module. The power module houses the flight controller, and mounts twin motors on the rear. Fitted with three-blade props, they propel the boat and allow it to be steered with differential thrust instead of a rudder. It’s then fitted with a camera to allow it to be piloted with an FPV headset.
Handling still isn’t perfect, and water on the FPV antenna causes some issues with video transmission. However, it’s a fun project that makes good use of old parts. Of course, if you’re having vibration problems with your own FPV projects, consider building a vibration-absorbing mount. Video after the break.
