Why this model

The model that has the receipts

At 2,788 m, air density is roughly 72% of sea level. A drone rated 450 kg at sea level does not deliver 450 kg there — most lose a third of rated payload before they lift. The LY400 delivered 410 kg of grid hardware on site, repeatedly, across a full construction cycle.

The same airframe has flown at 4,200 m in Liangshan and 4,300 m on a high-altitude logistics route. This is why the LY400 is the model we put forward for grid, plateau and mountain work: the derating curve is already documented in the field, not extrapolated from a test pad.

Configuration is 8-axis 16-rotor on T-MOTOR A16 or Hobbywing H15plus propulsion, with 73-inch one-piece straight props. High voltage, low current, large lift reserve — and motors that stay cool enough to keep flying through a full day.

Battery: four fast-charge packs (22 kWh) for continuous duty, or eight solid-state packs (40 kWh) for long-endurance routes. T-MOTOR lists the LY400 on its own website as a reference platform.

FAQ

Common questions on this model

How much payload can the LY400 actually lift at altitude?

The documented field figure is 410 kg delivered at 2,788 m. Above that altitude payload derates with air density. Send us your site elevation and ambient temperature and we will calculate the expected figure for your route.

What is the highest altitude the LY400 has flown?

4,300 m on a high-altitude logistics route, with a separate 4,200 m operation in Liangshan. These are documented jobs, not design targets.

Is the LY400 used for power grid construction?

Yes — that is its primary reference application. It has been used for tower erection support, conductor stringing and insulator transport on live grid projects.

Why does T-MOTOR list the LY400 on its website?

The LY400 uses T-MOTOR A16 propulsion, and T-MOTOR features the platform as a reference integration on its own site. It is an independent third-party endorsement of the airframe and power system pairing.
