2S 18650 MINI FPV DRONE

FPV drones are a fun but often costly hobby for beginners. Opting for a smaller drone will reduce the chance of damaging the drone when one invariably crashes, and the smaller props are also a lot safer if there are any innocent bystanders. In this project, we wanted a 3D Printable FPV drone that they could comfortably fly in-and-out of doors, so of course they built their own.

Once the drone’s frame was 3D printed, the most complex part about soldering four small-yet-powerful 8.5 mm motors to the AIO flight controller is ensuring that you attach them in the correct configuration and triple-checking them. A quick reshuffling of the battery connections and mounting the FPV camera all but completed the hardware side of the build.

Before plugging your flight controller into your PC to program, the battery must be disconnected unless you want to fry your board. Otherwise, flashing the board and programming it simply requires patience and a lot of saving your work. Once that’s done and you’ve paired everything together, the sky or ceiling is the limit!

We have made a tutorial video of the entire build, below we will also provide a full list of the parts needed, as well as alternative options like building the frame in less than 6 hours for anyone wanting to make their own and fly the same day.
