Key Features
- Brushless Motor Design — Brushless technology eliminates carbon brush wear and maintenance, providing you with a motor that requires minimal upkeep whilst delivering consistent power throughout extended flying sessions. This means longer motor life and better reliability compared to conventional brushed alternatives.
- 1950KV Rating — The 1950KV specification means the motor will rotate approximately 1950 revolutions per minute for every volt of input applied, allowing you to select appropriate propellers and gearing for your specific aircraft type and performance requirements.
- Inrunner Configuration — As an inrunner motor, the rotating shaft spins inside a fixed stator housing, creating a compact design that fits neatly into aircraft fuselages whilst still delivering excellent power and efficiency characteristics suitable for RC aeroplane applications.
- 4-Pole Motor Design — The 4-pole stator configuration optimises torque delivery and smoothness during operation, resulting in consistent thrust and predictable flight characteristics that serious RC pilots demand from their aircraft propulsion systems.
- Adjustable Timing — This motor features adjustable timing settings that allow you to optimise commutation advance based on your specific ESC, battery configuration and flying style, ensuring maximum efficiency and performance across different flight conditions.
- 4mm Bullet Connectors — The standard 4mm bullet connector type ensures reliable electrical connections with most brushless ESCs and power systems used in RC aircraft, making installation straightforward and connection secure for consistent power delivery.
- Designed for Aeroplanes — Purpose-built specifically for RC aeroplane applications, this motor's characteristics and specifications have been carefully engineered to deliver the power, efficiency and reliability that fixed-wing aircraft require for controlled, stable flight.
