Sub-250 depends on takeoff state
A 154 g bare aircraft leaves battery and accessories unresolved; only the fully identified measured build can support a mass statement.

Model:
The title, stored bill and black-airframe media support an Explorer LR 4 O4 identity and a 154 g bare-weight archive entry. The surrounding text also conflicts between 15 km and 20 km FCC references and mentions three-to-five-kilometre anecdotal use. Those distance statements are not combined or released. O4 Pro and O3 comparison material stays outside this item’s evidence file.


| Controlled section | Accepted source | Open question |
|---|---|---|
| O4 identity | Order, frame label, installed unit and filter | Current hardware revision |
| Bare mass | Stored 154 g record | Actual weighing state and accessories |
| Radio provenance | Conflicting 15 and 20 km FCC entries | Exact source, region and method |
| Recording workflow | Installed O4 mode and original files | Raw output and stabilization treatment |
A 154 g bare aircraft leaves battery and accessories unresolved; only the fully identified measured build can support a mass statement.
The three-to-five-kilometre narrative lacks the controlled conditions needed to settle either FCC figure.
Ask for the Explorer O4 controlled file, including the takeoff-state weighing and unresolved radio-source conflict.
