Performance Focused ESC for Multirotor Flyers

The Hobbywing XRotor 40A ESC, model number 30901001, is engineered to improve throttle responsiveness and flight stability on medium class multirotors. It uses a dedicated ESC profile to refine control compared with many stock firmwares. The device arrives with most parameters preset and leaves timing as the primary user-adjustable option.

Reliable Throttle Signal Handling

With a twisted-pair throttle lead the XRotor 40A reduces electromagnetic interference and delivers steady inputs to your flight controller. It supports throttle signal rates up to 621Hz to suit a variety of modern flight systems.

Durable Low-Resistance Design

High-quality MOSFETs give this ESC very low internal resistance while maintaining strong current capability. That improves efficiency and helps extend the service life of on-board electronics.

A dependable ESC choice for pilots seeking efficient power delivery and smooth throttle control on 550/650 class frames.

Will this ESC handle aggressive flying on 5S batteries?

Yes, the XRotor 40A is rated for up to 6S and can cope with spirited flights on 5S when paired with suitably rated motors and props.

Do I need extra cooling for long flights?

Good airflow over the ESC helps. While the low internal resistance reduces heat, extended high-current flights benefit from additional ventilation or mounting that allows airflow.

How do I calibrate throttle range?

Throttle range calibration is supported and usually done via your transmitter and flight controller following standard ESC calibration steps; refer to your FC documentation for the exact sequence.

Are the gold output connectors replaceable?

Yes. The 3.5mm female gold connectors can be replaced or re-soldered if needed, provided you maintain correct polarity and secure solder joints.
