Model:
X4-1900H revision reconciliation
Wheelbase:
The folding frame is described as 1900 mm, but propulsion identity remains held.
Flight Control:
X9 conflicts with X8 family evidence; require a revision-specific propulsion record.
Empty Weight:
Current conditions are missing for the archived 18 m/s value.
Power Battery:
Two auxiliary 6S 5300mAh batteries are listed without resolving aircraft identity.
Wingspan(without propellers):
The 1500 × 1500 × 650 mm unfolded figure requires a matching dated drawing.
Folded Size(without propellers):
The 900 × 800 × 650 mm folded figure stays provisional during identity review.
Empty Weight:
Keep 16 kg versus 14.5 kg empty mass visibly unresolved.
Satellite Navigation System:
Do not assign the multi-GNSS/RTK entry until equipment and revision match.
Endurance Time:
The old unloaded two-hour result cannot release the disputed heavy-payload build.
Maximum Horizontal Speed:
Current conditions are missing for the archived 18 m/s value.
Image Transmission:
Link wording remains held until the aircraft and installed radio are identified.
Electronic Speed Controller:
A 48 V, 3 kW source entry does not resolve the X8/X9 conflict.
This X4-1900H article names an X9 propulsion system, 16kg empty weight and 52kg maximum take-off entry. Nearby archived records for the same model family instead name X8 propulsion, 14.5kg empty weight and 29kg maximum take-off weight. Both also mention a 1900mm folding frame, 48V 3kW fuel cell, 12L cylinder and dual 6S 5300mAh batteries. The larger weight figure must remain disputed until a revision-specific structural and propulsion file supports it.
| Record | This article | Other archived family entry |
|---|---|---|
| Propulsion | X9 | X8 |
| Empty weight | 16kg | 14.5kg |
| Maximum take-off | 52kg at a stated throttle point | 29kg at a stated throttle point |
| Shared outline | 1900mm; 48V 3kW; dual 6S packs | Similar headline components |
Maximum take-off approval requires the exact propulsion model, propeller, frame revision, configured mass, centre of gravity, structural basis and controlled test evidence. Do not infer allowable equipment mass by subtracting two disputed numbers.
For inspection, survey or environmental sensing, record the equipment mass, mount drawing, power demand, data interface and balance. The supplier should then provide an acceptance result for that exact installation.
Send the intended civil equipment and ask for a serial-specific weight and propulsion dossier.
Hold performance release while the X8/X9 and mass conflicts remain unresolved.

Using this drone for scenic long-range flights has been an amazing experience. Controls feel smooth even at the edge of transmission range, and the battery life lets me stay airborne for extended sessions. Ideal for explorers and aerial photographers alike2025-12-30
My experience with the FPV Drone has been positive overall. The long-range capability is solid for cruising and exploration flights, and the stable flight characteristics in crosswinds give me confidence flying farther out. Perfect for intermediate pilots looking to push their limits2025-12-30
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
Long range FPV is incredibly fun, but you need to know what you’re doing. With proper setup and antenna orientation, you can push distances further. I lost signal once flying too quick without checking wind — lesson learned!2025-12-30
