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 Efficient Heavy Payload Endurance

Designed for 20–24 kg quadcopter UAVs that need efficient heavy payload operation compact transportation long service life and stable thermal performance under sustained loads

High Efficiency at Heavy Payload Hover Load

The validated I9 configuration delivers approximately 12.7 g/W at 4.5 kg thrust helping reduce continuous power demand during heavy payload endurance missions

Folding I36 Propeller for Easier Transport

The folding 36 inch propeller reduces the storage and transportation envelope of larger multirotor platforms while preserving a defined motor ESC and propeller configuration

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 frequent heavy payload missions across demanding outdoor operating conditions

Enhanced Heat Dissipation under Sustained Load

The integrated thermal design supports heat transfer from the motor and ESC during prolonged heavy load operation helping maintain stable propulsion output across extended duty cycles
