One compact airframe, one quick-swap battery, one operator. The Vantrel series is engineered to go from case to airborne without tools, a ground crew, or a second pair of hands.
Carbon-fibre-and-polyurethane arms, quick-release props and a sub-15-second battery swap let a single operator unpack, power up and launch from one case — no tools, no ground crew.
Vantrel 30 pairs an 8MP day sensor with 30× hybrid zoom; Vantrel Duo pairs a 5MP day sensor with a 384×288 thermal channel at 4× hybrid zoom. Both run onboard AI target identification and tracking across a 3-axis-stabilised, ±95° yaw gimbal.
FHSS frequency-hopping with AES channel encryption across 2.4 and 5.8 GHz control and video links, with sub-20ms control latency, so the mission feed can't be intercepted or spoofed mid-flight.
IP55-sealed airframe rated −20°C to +55°C, with a −15°C cold-soak launch capability from 21,000 ft, plus Auto-Home failsafe on link loss or low battery.
Most tactical quadcopters give up around 15,000 ft. The Vantrel series launches from 21,000 ft and holds a 27,000 ft service ceiling — deep into the thin air that grounds lesser airframes, just shy of Everest's own summit.
Vantrel 30 and Vantrel Duo share the same compact airframe, KAT7 Pro controller and encrypted datalink — the difference is what's on the gimbal.
The Sniper30 gimbal pairs an 8 MP day sensor with 30× hybrid zoom, stabilised across 3 mechanical axes plus EIS, with onboard AI handling target identification and tracking on every flight.

Both gimbals share the same aerial vantage at wide angle. Drive the master zoom to full telephoto and Vantrel 30's 30× reach isolates the target where Vantrel Duo's 4× day channel tops out — the trade for holding a thermal channel on the same turret.
At 0% both feeds are identical — same scene, same framing. At 100% Vantrel Duo holds at 4× while Vantrel 30 continues to 30×, a 7.5× tighter crop on the same target.
Both frames come from the Spectra384's Night Sight — a 384×288 px thermal imager refreshing at 30 Hz. Body heat cannot be camouflaged: personnel resolve as unmistakable hot signatures against the cool terrain, shown here in two of the sensor's 9 selectable colour palettes.
Every Vantrel mission runs over an FHSS + AES encrypted, dual-band link between aircraft and controller, so the mission map, live feed and telemetry can't be intercepted or spoofed mid-flight — controlled entirely from the KAT7 Pro.
The KAT7 Pro is a palm-sized, one-hand-operable controller running the KlmFly app — smart integrated aircraft control, live sensor feed and mission telemetry in a 5.5" FHD display, with dual-band radio diversity and 180 minutes of endurance on internal power.

Same compact airframe, same encrypted link, same one-man deployment. Pick Vantrel 30 for long-zoom stand-off identification, or Vantrel Duo for day-and-night dual-spectrum coverage.
The stand-off specialist. A 30× hybrid-zoom day sensor identifies targets from kilometres out, keeping the aircraft unseen and unheard.
The day-and-night specialist. A Spectra384 gimbal pairs day and thermal imaging in one turret, holding a target from first light through total darkness.
