8. Frequently Asked Questions
What is the maximum takeoff weight for a quadcopter using X1104 motors?Four X1104 motors provide approximately 400g total thrust (4 × 100g). For safe operation with 50% throttle hover, the recommended takeoff weight is 30-50g. This is perfect for sub-50g selfie drones and tiny whoops.
What propeller is recommended for micro drones?For 1-2" micro drones, we recommend 3020 (3x2.0 two-blade) or 3020-3 three-blade props. For tiny whoops, 1.6-2 inch props work well. The test report used 3020-3 three-blade propellers.
What battery voltage should I use?Voltage range is 1~2S. For maximum performance (40W), use 2S (7.4V). For ultra-light sub-25g builds, 1S (3.7V) provides sufficient power with minimal weight.
What is the maximum continuous current?For continuous operation (＞10 min), we recommend ≤4.5A (≈70% throttle). Brief peaks up to 8.0A are acceptable for punch-outs.
Can this motor be used for selfie drones?Yes. At only 5g, the X1104 is perfect for palm-sized selfie drones that fit in your pocket. Its high 4200KV provides responsive control for stable hovering and smooth selfie photography.
What is the thrust-to-weight ratio of this motor?The X1104 achieves an industry-leading 20:1 thrust-to-weight ratio (100g thrust / 5g weight) – over 20 times its own weight.
Is this motor suitable for nail polishing devices?Yes. The X1104's high RPM (31,000 no-load) and ultra-compact 5g size make it ideal for portable nail polishers and files. The 9N12P design provides consistent torque at high speeds.
What ESC is recommended for this motor?We recommend a 6A-12A BLHeli_S or BLHeli_32 ESC for drone applications. For handheld devices, a simple 1-2S PWM ESC is sufficient.
Do you provide custom winding (other KV)?Yes. KV can be customized from 3000KV to 6000KV for the X1104 stator. MOQ applies for custom KV.
Is there a test report for each motor?We provide batch sample reports. For OEM orders, individual test reports (including RPM, current, thrust, temperature) are available with additional QC fee.
