Plug-and-Play Industrial Flight Platform
A 6-axis industrial flight platform engineered as the base drive for light-duty UAV missions. Triple-IMU flight controller, dual RTK positioning, and IPX6/IPX7 power & battery management ship standard. Mission payloads attach via a unified PNP interface.
Core Technology
17 in-house engineered subsystems ship standard with every K8 — built around a triple-IMU flight controller and an IPX6/IPX7 power & battery system.
Lightest of the M6K Family
15 kg rated payload on a 1783 mm wheelbase. The smallest, lightest, most agile K platform — purpose-built for portable single-operator missions and rapid field deployment.
Broadest Battery Compatibility
12S 22–36 Ah standard — works with the widest range of off-the-shelf smart batteries on the market. Lower cell count, lower cost per cycle, easier field charging.
Compact Fold, 100 KV Motor
30-inch folding propellers driven by K8 motors at 100 KV. Lower per-axis thrust (5–7 kg) for efficient cruise — ideal for cameras, sensors, and lighter mission payloads.
Industrial-Grade In-House Flight Controller
6 Subsystems
Full-Cage Integrated Damping Chamber
All FC components are mounted inside a single vibration-isolated cage. The integrated damper structure cuts flight-controller vibration, protects IMU accuracy, and eliminates the need for field calibration.
Aviation-Grade J30J Gold-Plated Terminal
Oxidation-resistant, anti-vibration, firmly connected. Industrial-grade signal integrity.
Integrated Design · Minimal & Reliable
RTK, datalink, and compute core integrated into one board. Fewer connectors, lower failure rate.
Triple-Redundant IMU · Triple Safety Net
Three independent IMUs vote in real time. A single sensor failure will not interrupt flight.
Dual RTK Antennas for Heading
Two RTK antennas resolve heading directly. Anti-jamming, cm-level positioning, no compass dependency.
Integrated IMU Thermal Chamber
The IMU is held at a stable 45 °C regardless of ambient temperature, so sensor drift stays flat from -20 °C to +65 °C. Heading and attitude remain accurate in extreme environments.
Power & Battery Subsystems
11 Subsystems
In-House Smart Battery · Built-in BMS
Self-developed pack with built-in battery management. Hot-swap ready, balance-managed, cycle-counted.
FOC Vector Control with Flux Observer
Negative-pressure cooling, Miller-clamp driving, FOC vector control, and flux observer deliver industry-leading energy efficiency. Motor drive efficiency breaks 98%, and the system runs at lower temperature for longer service life.
IPX6 / IPX7 System-Wide Waterproofing
The full electrical path is sealed to IPX6/IPX7. Operate confidently in rain, spray, and coastal conditions.
MOS Thermal Optimization · TOLLT
Thermal resistance down 40%, response speed up 20%. Sustained high-current operation without throttling.
Integrated Copper Busbar
Current transfer efficiency up 5%. Lower impedance, lower heat, higher peak-current margin.
Strong Stability · Dual Backup
CAN + PWM dual independent control signals. A single-channel fault does not stop the motors.
Extreme Conditions · No Power Loss
Wide-temperature electronics and rugged power design keep the platform powered on through harsh environments — from freezing mornings to hot midday operations.
Six-Channel Temperature Sensing
Cells, MOSFETs, and key nodes all monitored. Precise thermal control and multi-level protection.
Massive Data Storage
Charge, discharge, and abnormal events are logged in real time. Full traceability for warranty and analysis.
High-Precision V / I / T Sampling
Voltage, current, and temperature are sampled at high precision with fast system response.
High-Performance High-Temperature Magnet
Motor magnets rated for sustained high temperature, preserving motor efficiency and demagnetization resistance over the full flight envelope.
