Select the I Series by MTOW Class

Five configurations cover quadcopter MTOW classes from 4 kg compact platforms to 48 kg heavy-lift multirotors. Each model combines optimized propeller sizing, integrated FOC ESC control, and application-specific quick-release or folding propeller architecture for predictable platform integration.

Why I Series for Long-Endurance UAVs?

The I Series is built around three engineering priorities: integrated propulsion for simpler airframe installation, high thrust efficiency for longer time aloft, and mission-ready reliability supported by thermal management, low-noise operation, and long service life.

Motor, ESC, and Propeller — Engineered as One System

Each I Series configuration combines the motor, FOC ESC, and matched propeller within one integrated propulsion architecture. This reduces separate component selection, shortens the integration path, and provides a more predictable performance baseline from prototype evaluation to production deployment.

  • Integrated FOC ESC reduces external component placement, wiring complexity, and installation time
  • Matched propeller sizing supports predictable thrust, efficiency, acoustic, and thermal performance
  • PWM and CAN communication options support flexible flight-controller integration
  • Quick-release or folding propeller architecture supports faster deployment and transport

High Thrust Efficiency That Extends Time Aloft

The I Series is engineered for multirotor missions where endurance directly determines coverage, productivity, and battery-cycle demand. Optimized propeller airfoils, system-level motor and ESC matching, and dedicated cooling paths help convert available battery energy into longer useful flight time.

  • I8 flight validation exceeds 300 minutes on an endurance-focused multirotor platform
  • I7 delivers more than 120 minutes of flight time in a validated long-endurance configuration
  • I7 reaches 13.23 g/W at 2.5 kg thrust under the referenced test condition, providing a model-specific efficiency benchmark
  • Expanded ventilation and propeller-driven airflow improve thermal stability during sustained operation

Long Service Life, Low Noise, and Mission-Ready Reliability

Repeated commercial missions require propulsion that remains stable across thousands of operating cycles. The I Series combines condition monitoring, temperature protection, low acoustic output, and durable propeller interfaces to support high-frequency field use.

  • 10,000-hour service-life design supports high-frequency commercial mission profiles
  • I7 records 65–67 dB at 5 m, supporting urban, public-safety, and wildlife-sensitive operations
  • Health monitoring and ESC protection provide voltage, temperature, RPM, and current-status visibility
  • Operating capability across model-specific temperature ranges up to −30°C to 65°C

I-SERIES

Built for Missions That Demand Hours, Not Minutes

I Series propulsion supports multirotor UAVs that must cover more ground per flight, remain on station longer, and reduce battery-change interruptions — while maintaining low acoustic output and predictable performance across repeated missions.
