❓ Frequently Asked Questions
Q1: What UAV takeoff weight is suitable for the X11PLUS-85KV?
Recommended continuous thrust per motor: 10-25kg (40%-70% throttle). For 4-axis configuration, total takeoff weight: 80-140kg. For 6 or 8-axis configurations, supports 120-200kg class heavy-lift platforms.
Q2: What's the difference compared to X9-110KV?
The X11PLUS-85KV features a larger stator (Φ111×18mm), higher voltage rating (14S), max power 7107W, and max thrust 37.38kg. Designed for heavier payload requirements and industrial drone applications.
Q3: Can I use other propellers?
Yes. Test data is based on MFP 43×14 propeller. Alternative propellers from 38-46 inches can be used, but thrust and current must be re-validated to avoid overload. Custom thrust optimization services available.
Q4: What is the motor temperature limit?
Insulation rating: Class H (180°C). Recommended continuous operating temperature: <130°C (case temperature <85°C). Built-in temperature sensor with customizable feedback interface.
Q5: What ESC is recommended?
Recommended 14S 150A-200A ESC with PWM/DShot/CAN protocol support. Please choose ESCs from reputable brands to ensure adequate cooling and continuous output capability.
