Model:
X4-1900H service and logistics dossier
Wheelbase:
Service register starts from the archived 1900 mm X8 family designation.
Flight Control:
Name the maintained fuel-cell and propulsion-control revisions before support begins.
Empty Weight:
Set the project speed ceiling separately from the old 18 m/s listing.
Power Battery:
Two 6S 5300mAh auxiliary packs are historical references requiring label checks.
Wingspan(without propellers):
Maintenance drawing records 1500 × 1500 × 650 mm unfolded; verify after assembly.
Folded Size(without propellers):
Logistics record gives 900 × 800 × 650 mm folded; measure the packed service unit.
Empty Weight:
Resolve 14.5 kg versus 16 kg by weighing the supported configuration.
Satellite Navigation System:
Identify the receiver behind the generic multi-GNSS and RTK option.
Endurance Time:
Two hours without payload remains an old service-family reference, not acceptance.
Maximum Horizontal Speed:
Set the project speed ceiling separately from the old 18 m/s listing.
Image Transmission:
Maintain model, frequency and approval records for any quoted communications link.
Electronic Speed Controller:
Record the serviced unit that corresponds to the old 48 V, 3 kW entry.
This X4-1900H archive describes a 1900mm X8 folding platform, 48V 3kW fuel-cell reference, 12L cylinder at 350 bar, two 6S 5300mAh auxiliary batteries and a 29kg maximum take-off entry. Its source body says 14.5kg empty while an old field says 16kg. That discrepancy changes the remaining payload allowance and must be resolved on the current weight sheet.
| File | Archived detail | Current proof |
|---|---|---|
| Weight sheet | 14.5kg body entry; 16kg field entry | Calibrated empty and configured mass |
| Fuel cell | 48V, 3kW | Model, limits, startup and shutdown manual |
| Cylinder | 12L, 350 bar; 4.3kg full reference | Certification, valve, inspection and transport record |
| Auxiliary power | Two 6S 5300mAh packs | Wiring role, charger and isolation procedure |
Cylinder filling, storage, vehicle carriage and local facility rules can determine feasibility. Identify trained personnel, approved replacement parts and the maintenance location before treating long duration as an advantage.
Record the airframe serial, fuel-cell model, cylinder identity, battery set, installed civil sensor and centre of gravity. A payload-free archive result cannot be transferred to an inspection configuration.
Share the intended civil sensor, operating region and service arrangements before configuration approval.
Connect every mass and energy-system entry to one maintained aircraft revision.

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
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
The long-distance capabilities of this drone impressed me right away. It kept a reliable link out to several kilometers, and the sturdy build handled a few rough landings without issue. A solid choice for expansive FPV flights2025-12-30
This long range FPV drone did what I expected: extended signal and smooth video. Just be mindful of battery life and wind conditions — pushing too far without planning can risk signal loss or low power return2025-12-30
