WhyCopperhead

No Launch Infrastructure

Lifts off vertically on its own two motors and lands back on its tail. No runway, catapult, net or launcher — the aircraft and an operator are the whole system.

Survey-grade positioning

u-blox F9P RTK with matching base station, dual redundant heater-stabilized IMUs and dual magnetometers — accuracy that holds in high heat and sub-freezing air.

Over an hour on station

70–73 minutes with a real payload aboard and 64.6–67.7 miles of still-air range, working out to 21.7 miles and back. Payload barely costs you endurance.

Built to be repaired

PA-12 nylon airframe, Multi Jet Fusion printed, designed to a 7.5 G limit load and tolerant of hard vertical landings and tip-overs. A damaged panel is a reprint, not a rebuild.

Launch toRecovery

1

Vertical launch

Lifts off tail-down from any clear patch of ground.

2

Transition

Pitches over into wings-level flight and accelerates to cruise.

3

Cruise

55.9 mph on ≈250 W at a lift-to-drag ratio of 19.7

4

Transition back

Decelerates and pitches nose-up over the recovery point.

5

Vertical landing

Descends onto its tail. Sized for hard landing.

IntroducingC6Layla

Ceres Air C6 Layla spray drone in flight

A 25 L spray platform on a four-axis truss airframe with dual centrifugal nozzles, RTK dual-antenna positioning and 360° radar obstacle avoidance — now specified with a 30 Ah 18S smart battery and a 9 kW fast charger, doubling on-board energy without extending turnaround.

30 Ah · 18S Battery9 kW Volt Smart 4.6 charger30 Ah 18S Battery

Effectof the 30AhBattery

The C6 manual specifies the HE103 pack at 1,012 Wh (14,992 mAh, 20.9 lbs). The 30 Ah 18S pack doubles on-board energy to approximately 2,025 Wh for 28.7 lbs — a step from 48.5 to 70.8 Wh/lbs in cell energy density, so the aircraft gains all of the energy for only 7.7 lbs of mass.

A grille-type structure with 700% more dissipation area and combined active and passive cooling holds the pack below 149°F, and rated life is 1,500 cycles at under 7% degradation. Paired with the 9 kW Volt Smart 4.6 charger, charge time is unchanged.
