how to build a drone
For this course, we have selected a frame that has become a benchmark in the community: the JeNo. Available in 3 or 3.5-inch versions, this model strikes the perfect balance for those seeking the compactness of a small drone without sacrificing the power and cinematic quality of larger rigs. It is the ideal learning platform—forgiving of mistakes yet capable of competition-level performance.

Why this specific frame
The JeNo is a high-performance 'Open Source' project born from the passion of French designers. Unlike generic industrial products, its 'Deadcat' geometry was engineered to clear your field of view: no props will ever obstruct your HD footage. Its T700 carbon structure offers exceptional rigidity, making it easier to tune your flight controller and ensuring maximum durability during intense freestyle sessions.
The Essentials:
Before picking up the soldering iron, the very first step is getting the right parts, Here is the essentials to get started.
- The Frame: JeNo 3" or 3.5" (Carbon plates, hardware, and TPU 3D prints)
- The Stack: 20x20 Mini Stack (Combined FC & ESC) capable of at least 35A.
- Motors: 1404 to 1604 brushless motors (depending on 3" or 3.5" choice.
- Digital/Analog VTX: DJI O3, Walksnail, or Analog system for your video feed.
- The Props:HQProp or Ethix propellers matching your motor size.
- Battery: 4S or 6S LiPo (850mAh is the sweet spot for this build).
Step 1: Frame Assembly (Carbon structure setup and arm securing). Step 2: The Electronic Heart (Stack installation: ESC/FC orientation and data flow). Step 3: Propulsion & Soldering (Motor mounting and critical wire management to prevent interference). Step 4: Video & Radio Link (Setting up HD/Analog transmission and the control link). Step 5: Software Configuration (Betaflight flashing, flight modes setup, and motor direction testing).
