Integrated by Design Validated as a System

Motor ESC and matched propeller are engineered as one propulsion architecture to reduce integration work improve system consistency and provide a validated starting point for UAV platform development

Motor and ESC Integration

A compact integrated architecture reduces external wiring connector count and installation complexity while supporting more consistent electrical control and thermal behavior

Matched Propeller Setup

Propeller sizing is selected around the motor and ESC operating range to balance thrust efficiency current draw and thermal load at system level

Faster Platform Integration

A defined propulsion configuration reduces component sourcing compatibility testing and repeated tuning during prototype development

System Level Performance Data

Thrust efficiency current RPM and temperature are evaluated as a complete propulsion system to support airframe selection and validation

Engineered for Five Hour Endurance and Extended Duty Cycles

Designed for 16–18 kg quadcopter UAVs that need verified multi hour efficiency project specific deployment options long service life and dependable thermal performance

Five Hour Class Endurance from High Efficiency

The I8 propulsion platform has supported more than 300 minutes of verified flight time demonstrating the efficiency required for persistent surveying inspection and monitoring missions

Custom Quick Release Propeller Configuration

A quick release propeller configuration can be developed for project specific integration helping simplify installation transportation and field deployment for compatible UAV platforms

Long Life Protection and Wide Temperature Reliability

Core components are developed around a 10,000 hour service life target while IP46 protection and a recommended ambient temperature range from −30°C to 65°C support high utilization UAV platforms operating across dust moisture cold starts and elevated daytime temperatures

Enhanced Heat Dissipation for Multi Hour Operation

The motor and ESC thermal architecture is designed to move heat away from critical components during prolonged operation helping maintain stable output across extended mission durations
