Key Takeaways
1. Sam built the “world’s smallest FPV drone,” measuring just 22.3 millimeters from motor post to motor post.
2. The drone was created by repurposing parts from a 64.8-millimeter BetaFPV Air65 drone.
3. The body of the drone was designed and 3D printed using a Bambu A1 Mini 3D-printer.
4. Sam made significant firmware adjustments due to the changes in the drone’s design, requiring multiple test flights.
5. The drone weighs 25 grams and has a flight time of about 3 minutes with a 300 mAh battery.
DIY engineer Hoarder Sam has built the “world’s smallest FPV drone,” which is an impressively tiny device measuring only 22.3 millimeters from motor post to motor post. This bold creation features all four rotors overlapping, giving it a chaotic appearance, yet it managed to take flight.
Components and Construction
To create this miniature marvel, Sam dismantled the 64.8-millimeter BetaFPV Air65 drone, which is currently priced at $125.99 on Amazon. He utilized its parts, including the flight controller, camera, rotors, and propellers. Additionally, he designed and 3D printed the body of the drone using a Bambu A1 Mini 3D-printer, available for $249 on Amazon.
Flight Tests and Performance
Sam also adjusted the firmware due to the major design alterations he made to the original drone’s framework. It required several adjustments and test flights to achieve successful flying. The unnamed drone ultimately weighed only 25 grams.
By using a 300 mAh battery, he achieved approximately 3 minutes of flight time. However, when he switched to a 260 mAh battery pack, the flying duration dropped by around 30 seconds.
