The Hobbywing XRotor 3115 900KV is a high-performance FPV brushless motor designed for powerful 9–10 inch FPV drones. With strong torque, high thrust output, and reliable cooling, it is ideal for long-range, freestyle, and cinematic FPV applications.
Built with premium materials, optimized electromagnetic design, and an efficient self-cooling rotor structure, the XRotor 3115 900KV delivers stable power, smooth throttle response, and dependable performance during demanding flights.
High-Efficiency Heavy-Load Performance
The XRotor 3115 900KV is optimized for strong heavy-load efficiency and stable power delivery.
With up to 5177 g of maximum thrust, it provides the power needed for large FPV drones carrying bigger batteries, HD systems, or cinematic payloads.
Its 900KV configuration is well suited for 4–6S LiPo setups, offering strong torque, efficient control, and smooth throttle response.
Efficient Cooling Design
The rotor uses a cooling structure to improve heat dissipation during flight.
This helps reduce temperature rise under load and supports more consistent performance during demanding FPV use.
Anti-Slip Propeller Mount
The motor uses a tooth-groove anti-slip propeller mount design.
This helps prevent propeller slippage during high-throttle operation, improving safety and maintaining consistent thrust output.
Premium FPV Construction
The XRotor 3115 uses high-performance 0.2 mm silicon steel sheets for improved efficiency and reliability.
Its 200°C high-temperature resistant enameled wire improves durability under demanding FPV use.
The 12N14P motor structure provides smooth operation, strong torque, and reliable throttle response.
