High Torque FPV Drone Motor for Long Range & Heavy Lift - QPT 3115 900KV Brushless Motor.

QPT 3115 900KV High-Torque Brushless Motor

The QPT 3115 900KV is a heavy-duty workhorse. Unlike high-speed racing motors that prioritize pure RPM, the 3115 series is engineered for leverage and endurance. With its massive 31mm stator diameter, it generates the substantial torque required to swing 8-inch to 10-inch propellers, making it the ideal choice for long-range exploration, aerial photography, and industrial UAV applications where stability and flight time are non-negotiable.

Designed for Heavy Lifting

This motor is built to handle the "heavy stuff." Whether you are mounting a high-end cinema camera, a larger GPS module, or a high-capacity 6S LiPo/Li-Ion battery pack, the QPT 3115 handles the extra mass with ease. Its high-torque magnetic circuit ensures that your drone remains agile and responsive despite the added weight, while the 900KV rating provides a perfectly tuned RPM band for efficient cruising.

Efficiency and Reliability

Long-range flying is all about maximizing your time in the air. The QPT 3115 is optimized for high-voltage (6S) efficiency, keeping current draw manageable and motor temperatures low even during long, sustained flights. With its robust construction and high-quality bearings, it is built to survive the rigors of field operations, providing a reliable power system you can trust when you are miles away from the takeoff point.

Key Features

• High-Torque Performance: Specifically designed to swing 9-10" propellers for maximum lift and efficiency.

• Optimized for Long-Range: 900KV rating provides the perfect balance of thrust and efficiency for 6S setups.

• Heavy-Lift Capable: Engineered to handle the high demands of cinematic rigs and large payload drones.

• Robust Construction: High-grade components and an efficient cooling structure ensure long-term durability and thermal stability.

• Anti-Slip Prop Mount: Includes an advanced grooved propeller mount design to keep your large props secure and prevent slipping.

Why Pilots Choose the QPT 3115

Pilots who fly 10-inch "beast class" drones choose the QPT 3115 because it offers a "no-nonsense" approach to power. It’s an accessible, reliable, and high-thrust motor that turns a large, lumbering drone into a smooth, stable aerial camera platform. If you’re building a long-range rig meant to conquer the horizon, this is the propulsion system you need.
