RTK to the centimetre
Dual-antenna RTK on the AX4, carrier-phase RTK on the X8 and X9. Heading from the antennas, not the compass, so steel structures don't pull the aircraft off line.

A folding carbon quadcopter with a 360° LiDAR in its nose, a dual-sensor thermal gimbal under its chin and a solid-state battery that slides in from the tail. Scroll to take it apart, piece by piece.

01 · Transport
Inward fold
The front arms sweep back along the body, then the rear pair tucks forward underneath. Folded, the aircraft is 510 × 350 × 380 mm with the props and camera off, small enough for a backpack case.

02 · Shell
Moulded fuselage
A faceted polymer fuselage, 270 × 150 × 96 mm, with a 45° black-glass nose, side light bars and a fan-ducted bay that keeps the battery and avionics cool at 36 °C.

03 · Sensors
LiDAR, gimbal, altimeter
The 360° LiDAR is built into the nose at 45° so it sweeps from the horizon to the ground ahead. Below it, a quick-release 3-axis gimbal carries a 4K camera and a 640 × 512 thermal core.

04 · Propulsion
Folding carbon arms
Four 20 mm carbon tubes fold inward for transport. 5008-class motors turn 17-inch one-piece carbon props: the front pair inverted, the rear pair upright with LED orientation rings.

05 · Power
Tail-loading cartridge
A 6S 16 Ah solid-state pack, 355 Wh and 1.49 kg, slides in from the tail and latches without tools. Its outer skin is part of the fuselage, so nothing hangs off the aircraft.
Battery cartridge
06 · Avionics
One deck, everything on it
The autopilot, 4-in-1 ESC and the digital link's air unit share one deck inside the fuselage. The link carries RC and video for kilometres, and fails over to 5G cellular on its own.

07 · Ground
Fixed carbon gear
Straight 16 mm carbon legs on 10 mm skids. No folding mechanism to fail, and enough ground clearance for the gimbal to look straight down on landing.

The stack
One brain,
four airframes
The AX4, X8, X9 and FX7 share the same open flight stack, the same handheld ground station and the same permission workflow. Train a crew once and they can fly the whole line.
Positioning
Command link
Digital link, 5G failover
Long-range digital RC and video out to 15 km on the heavy-lift platforms. If the link drops, the AX4 fails over to 5G cellular automatically and the mission carries on.
Payloads
Quick-release everything
The AX4's gimbal and battery swap without tools. The X8 and X9 take firefighting, rescue and logistics modules on one mount. The FX7 drops a 1.5 kg payload on command.
Environment
Built for 36 °C
Fan-ducted battery and avionics bays, sealed motors and conformal-coated boards. Full endurance is rated at 36 °C ambient, not at a lab temperature.
Tethered
Unlimited time on station
The X8 and X9 fly tethered on ground power and water for facade cleaning and fire suppression, so endurance is set by the shift, not the battery.
Training
Sim first, then fly
Crews build stick time and release discipline in the FPV simulator, then transfer straight onto the FX7. The same ground station flies every aircraft in the line.
Compliance
Built to the
Drone Rules
Indian airspace is zoned, registered and logged. Vayuveer aircraft are engineered for that system rather than adapted to it afterwards.
UINDigital Sky
Unique Identification Number per aircraft; flight logs retained as the rules require.
NPNTNo permission, no take-off
Permission artefacts are fetched, signed and logged on the aircraft before every flight.
RPCPilot training
Remote Pilot Certificate courses through a DGCA-approved training partner.

AX4 and FX7 in the Small class; X8 and X9 at the Small-to-Medium boundary.

answers
What buyers ask first. If yours isn't here, the form below reaches an engineer, not a mailbox.
What does Vayuveer build?
Four aircraft: the AX4 folding surveillance and mapping quadcopter, the X8 and X9 heavy-lift octa-quads for firefighting, water rescue and logistics, and the FX7 7-inch FPV payload quadcopter.
What is the AX4's endurance?
About 34 minutes of hover at 36 °C with a 20 percent reserve, or about 38 minutes in cruise, on a 6S 16 Ah solid-state battery. These are design estimates from calculation, not flight-test results.
Are Vayuveer drones made in India?
Yes. The airframes, flight stack integration and ground stations are designed and assembled in India.
Do the aircraft comply with the Drone Rules?
They are engineered for the Indian system from the start: Digital Sky registration, NPNT, and the DGCA type-certification pathway. The AX4 and FX7 fall in the Small class, the X8 and X9 at the Small to Medium boundary.
How much can the X8 and X9 carry?
The X8 carries about 20 kg and the X9 about 30 kg, with firefighting, rescue and logistics modules. Both can fly tethered for unlimited time on station.
How do I request a demo?
Use the form below or write to hello@vayuveer.in with where the aircraft would fly, how often, and what it should carry or see.
