Finger-Sized FPV Drone

The Goal

I wanted to see how small I could build a functional FPV drone. The goal was to make a quadcopter about the size of a LEGO minifigure that could still fly around the house and transmit video.

Custom Shrouds

Because the props are so tiny and fragile, any bump against a wall would break them. I 3D printed custom shrouds to protect the rotors.

• Design: Lightweight PLA guards that clip onto the frame.
• Purpose: These allowed me to crash into walls and keep flying, which is essential for indoor flying.

Specs

• Size: About 4cm wide.
• Camera: All-in-one FPV camera and transmitter.
• Flight: Micro flight controller and brushed motors.

Result

It flew well indoors and was stable enough to navigate through tight spaces. I eventually lost it when I tried flying outside—it was so small and light that a gust of wind carried it away into the grass. But it proved that micro-scale FPV is feasible.
