Heavy-Lift FPV Motors (2406–3115)

In this category, we have gathered the most powerful brushless FPV motors intended for building large and demanding drones. You will find units with robust stator sizes, from 2406 up to powerful 3115, designed for payload capacity and long flight times. These are motors for special tasks, such as:

• Long-distance Long Range flights
• Cinelifter platforms capable of carrying GoPro cameras, and even larger ones
• Stable and reliable X8 (eight-motor) configurations
• Professional applications: video production, inspections, mapping

These motors work with large propellers (6, 7, 8, 9 inches and larger) and are most often powered by 6S LiPo batteries (or higher voltage in advanced projects). Their main task is to provide high thrust, flight stability even with heavy payloads, and energy efficiency allowing for extended time in the air. The dominant manufacturer in this segment, offering proven and reliable solutions, is T-Motor.

Selecting motors for a large FPV drone requires careful analysis to achieve the desired performance and reliability. Key factors include:

• Required Thrust and Efficiency: Determine the drone's all-up weight (with payload and battery) and choose motors providing adequate thrust margin (a thrust-to-weight ratio of at least 2:1 is often recommended, even higher for dynamic flights). Analyze thrust test tables provided by manufacturers, paying attention to efficiency (grams per watt - g/W) at the expected load and cruise speed.
• Stator Size (e.g., 2808, 2812, 3115): A larger stator means more torque, better handling of large, low-RPM propellers, and potentially higher efficiency in level flight, but also increases motor weight. Choose the size based on the planned propeller size and flight characteristics.
• KV Rating (RPM/V): In this segment, KV values are significantly lower than in smaller motors (often 600KV - 1300KV). It must be precisely matched to the propeller size and battery voltage (most commonly 6S). Lower KV with larger props favors efficiency and long flights.
• Build Quality and Cooling: Heavy-lift motors operate under high load. Robust construction, high-quality bearings, and effective cooling are essential for reliability during long missions.
• Voltage Compatibility: Most motors in this class are optimized for 6S LiPo, but always check the manufacturer's specifications for the maximum allowable voltage.

Remember to choose sufficiently strong frame arms and ESCs with ample current headroom capable of handling the power of these motors.

Building a long-range drone, cinelifter, or other large FPV platform is an ambitious undertaking. Wondering which motor size – 2808 or maybe 3115 – is right for your project? What KV rating should you choose for 8-inch props and 6S packs? Are T-Motor motors the best choice in this class?
