About JeNo 5.1

JeNo 5.1 is an open-hardware 5.1-inch FPV drone frame for freestyle, freeride and cinematic flying, designed around the DJI Air Unit O3/O4 with an unobstructed field of view. The repo provides DXF, STEP and STL files for the carbon frame plus 3D-printed TPU protection, with Classic, Light and Bando variants and several camera plates. The 3D view shows the frame only, without motors, props, battery, flight electronics, wiring or TPU parts.

How to build JeNo 5.1

5 steps

Steps marked Motari summary condense the linked source; follow the source for exact instructions.

  1. Cut or order the carbon

    Order frame cuts from the DXF/STEP files, or buy a pre-cut version from a retailer. Arms are 6 mm for rigidity.

    Motari summarygithub.com/WE-are-FPV/JeNo-5.1/blob/main/OTHER-FILES/JeNo5_A...

  2. Print TPU protection

    Print the TPU parts you need from the 02-TPU folder, such as bumpers, arm protections, antenna supports and action camera mounts. The camera plates themselves are carbon.

    Motari summarygithub.com/WE-are-FPV/JeNo-5.1/blob/main/OTHER-FILES/JeNo5_A...

  3. Assemble the frame

    Follow the PDF assembly manual: stack the plates with M3x30 standoffs and countersunk screws.

    Motari summarygithub.com/WE-are-FPV/JeNo-5.1/blob/main/OTHER-FILES/JeNo5_A...

  4. Install the stack and video system

    Install the stack screws before the middle plate, then mount a 30.5 x 30.5 mm or 20 x 20 mm flight stack and the video system (DJI O3 or O4 Pro, Vista, WalkSnail, HDZero or analog) on the camera plates.

  5. Final wiring and tune

    Wire your electronics per their own manuals, then load the JeNo tune preset for Betaflight 4.4 or 4.5 from the WE are FPV preset source.

Builds of JeNo 5.1

0 reviewed

No reviewed builds of JeNo 5.1 yet.

A build log records the evidence (photos, a video, your repository), what the build cost, how long it took and what you changed. Each one is checked by Motari (until a maintainer claims this page) before it shows here, and reviewed builds count toward the reproducibility score.
