Manual for XM series Brushless Motor Electronic Speed Control

Thanks for purchasing our Electronic Speed Controller (ESC). The brushless system with high

power for RC model can be very dangerous, so we strongly suggest you read this manual carefully.

Any claims arising from the operating, failure or malfunctioning etc. will be denied. We assume no

liability for personal injury, property damage or consequential damages resulting from our product

or our workmanship. As far as is legally permitted, the obligation to compensation is limited to the

invoice amount of the affected product. At the same time, We do not assume any liability arising

from modifications due to unauthorized product. We reserve the right to change without notice

about product design, appearance, performance and operational requirements.

Specification:

◆Signal frequency：20-500Hz/ Oneshot125 Ultra high speed

◆Firmware：BLHeli

Feature：

◆ XM series esc is the upgraded version from SN series with advanced processor, the basic

frequency up to 50MHz and processing capacity is faster to support high KV motor.

◆ Specially for Multi-copter, throttle respond fast;

◆ Suit for throttle, which can compatible well with motor;

◆ Throttle signal is twisted pair cable, reduce the signal crosstalk effectively while transmission in

the copper wire to flight more stable;

◆ New miniaturization and ultra-low resistance MOSFET, powerful flow resistance, and

professional MOS Drive chips to improve efficiency. PCB board processed with special thickness

treatment, low resistance and calorific value, higher impact resistance.

◆ Subminiaturization design, 10/20A with high performance filtering capacitor on the board to

reduce the weight. Long bar XML20A is designed for the frame with arm tube, suit for the Φ10mm

tube to make it more neat.

◆ Support refresh rate of throttle signal maximum up to 500Hz, compatible with all flight controls;

Support ultra-high speed Oneshot125 and 3000Hz high refresh rate, fast response, better throttle

liner and smooth shooting to be the first choice for multicopter and racing frame.

◆Throttle lever travel and other settings are available to be set by USB linker; Support two-way

mode and 3D mode for racing frame.
