Key Advantages & Use Cases

1. Heavy-Lift Cargo Drones

With up to 12 kg thrust, the MN801-S is an excellent motor for heavy-payload drones used in logistics, agriculture, and material transport.

2. VTOL UAV Applications

Powerful torque and high efficiency make it suitable for vertical takeoff and landing aircraft, providing stable lift during transition and cruise phases.

3. Fixed-Wing UAVs

Large fixed-wing drones that require high thrust for takeoff or heavy payload capability benefit from the motor's robust design and wide voltage flexibility.

4. Industrial Missions

Ideal for mapping, surveying, inspection, forestry, and long-endurance industrial missions thanks to its IP45 protection and reliability.

Integration Guidelines

• Ensure ESC and cables support the peak current draw.
• Select proper propeller sizes to match the KV rating.
• Allow adequate cooling airflow around the motor.
• Perform periodic lubrication for long-term performance.
• Use vibration-damped mounting structures for optimal balance.

Limitations to Consider

• Larger size and weight compared to hobby-grade motors.
• Requires large frame clearance for 26 - 29 inch propellers.
• IP45 protects against splashes, but not immersion.
• Higher power consumption under heavy load.
