In a world where advanced drone technology often comes with a four-figure price tag, a DIY engineer is proving that high-tech capabilities don't have to break the bank. Hoarder Sam, a popular YouTuber known for his inventive drone content, has done it again. He recently unveiled a fully functional, semi-autonomous drone capable of waypoint navigation and carrying a 2-pound payload, all for a staggeringly low total cost of approximately $220.
The project, detailed in a comprehensive video on his channel, demonstrates that with the right knowledge and a bit of ingenuity, creating sophisticated unmanned aerial vehicles (UAVs) is more accessible than ever.
From Scratch to Sky: The Build Process Unveiled
Staying true to his channel's ethos, Hoarder Sam’s latest video is more than just a showcase; it's a step-by-step guide. He meticulously documents the entire construction process, from unboxing components to the final calibration. This transparency is a goldmine for fellow DIY enthusiasts and aspiring drone builders, demystifying the often-intimidating world of autonomous flight.
The bulk of the parts were sourced from online retailers, emphasizing the project's accessibility. For the custom pieces that couldn't be bought off-the-shelf, he turned to 3D printing, a technology that has become a cornerstone of modern DIY projects. Notably, the single most expensive component was the flight controller, which cost just $42.45—a fraction of the price of controllers found in many commercial drones.
The Brains and Brawn: Key Components for Autonomy and Power
What separates this homemade drone from a simple remote-controlled toy is its sophisticated suite of features. At the heart of its "semi-autonomous" capability is the HGLRC-M100 mini GPS unit. This compact module, which includes a built-in compass, is the key to the drone's intelligent flight modes.
With this GPS, the drone can perform two critical functions:
- Position Hold: It can automatically maintain a stable hover in a fixed location, even in the presence of light wind, without constant pilot input.
- Waypoint Navigation: The pilot can pre-program a flight path by plotting specific GPS coordinates on a map. The drone will then autonomously take off, fly to each waypoint in sequence, and return to its starting point—a feature once reserved for high-end commercial and professional drones.
For communication, the drone relies on a standard radio control system, giving the operator manual override and control at all times. But the innovation doesn't stop there.
Payloads and Parachutes: The Ingenious Airdrop System
Moving beyond simple flight, Hoarder Sam equipped his creation with a practical payload capability. He engineered a simple yet effective latch-based "airdropping system" using an MG995 servo motor. This allows the drone to carry items weighing up to roughly 1 kilogram (2.2 lbs) and release them on command from the transmitter.
This opens up a world of potential applications, from delivering small supplies to remote locations to conducting amateur scientific experiments. For those looking to replicate this feature, a reliable servo motor is crucial.
For builders inspired to start their own project, a high-torque servo motor like the one used is an essential component. You can find a suitable model online.

A Pattern of Innovation: Hoarder Sam's DIY Pedigree
This impressive build is not a one-off for the resourceful engineer. His channel is a testament to pushing the boundaries of what's possible in a home workshop. Just days before this reveal, he made headlines with another miniature marvel: a successfully flown drone measuring a mere 0.88 inches from motor post to motor post, featuring four overlapping propellers. While its flight time was a brief two and a half minutes, the achievement highlighted his expertise in micro-scale aviation and complex design.
Democratizing Drone Technology, One Build at a Time
Hoarder Sam's $220 semi-autonomous drone project is more than just a cool DIY build; it's a significant statement in the world of technology. It proves that advanced features like GPS navigation and payload delivery are no longer locked behind corporate R&D departments and hefty price tags.
By sharing his process openly, he is empowering a new generation of makers, students, and hobbyists to explore the skies. This project serves as a powerful reminder that with creativity, patience, and a well-stocked online parts cart, the sky is truly not the limit. For anyone who has ever dreamed of building their own drone, the blueprint is now available.
