An INAV-labelled seven-inch aircraft requires a configuration-led handover. Freeze firmware, navigation sensor, receiver, battery and installed mass before any supervised result is attached to this build. Article 2428 has a locked archived lead image but no retained gallery images in its pics field. The displayed same-article source image is a provenance exhibit only; it does not close the identity review. Its text lists a seven-inch X4-7, 45A four-in-one ESC, 4S 5100mAh battery, 1.35kg empty-weight entry, 915MHz receiver reference and INAV or Betaflight support, although the title specifically names INAV. An old issue says twenty minutes while the visible field says thirty. Until current identification photographs and a build sheet are supplied, the page should remain a document-led configuration hold.
| Evidence | Archive state | Required delivery |
|---|---|---|
| Model identity | Locked lead image; no retained gallery images | Current overall and component-label photographs |
| Controller | INAV title; INAV/Betaflight text | Board, firmware target and backup |
| Power | 45A ESC; 4S 5100mAh | Motor, propeller, connector and battery labels |
| Duration | Twenty-minute issue; thirty-minute field | Configured test with mass and reserve |
Request photographs of the complete aircraft, frame, controller, ESC, motors, battery, receiver and video equipment. Connect those images to a dated parts list rather than reusing pictures from a neighbouring X4-7 article.
Identify the controller target, GNSS receiver, compass if fitted, antenna placement, calibration notes and saved settings. Firmware capability alone does not prove installed navigation hardware.
It establishes only that this image belongs to the article archive; the open identity check prevents it from proving the supplied build.
It preserves identity, but board, firmware and sensor evidence are still required.
Neither until the selected battery, mass, conditions and reserve are documented.
Ask for current model photographs and a matching INAV build sheet before release.
Tie navigation behaviour to a frozen controller and power configuration.

I’ve tried several FPV drones, and this one stands out for quality and performance. The build feels solid, and the video feed is crystal clear. Definitely recommended for serious hobbyists.2025-12-29
I regularly fly over fields and forest trails, and this long range FPV drone never disappoints. The signal range is excellent, and it’s stable even in moderate winds. It’s become my go-to for remote adventure flights and scenic FPV clips2025-12-30
I mounted a lightweight camera on my Long Range FPV and got stunning FPV footage over open fields and trails. The signal stayed strong over long distances, and the build held up well to minor bumps. Definitely a great rig for scenic long flights2025-12-30
This long-range FPV drone gives me real confidence when flying far from the launch point. Signal penetration remains stable over open terrain, and the video feed stays clear enough to judge distance and orientation accurately. With proper battery planning, I can comfortably explore wide areas and s2025-12-30
