DYS 20 Amp XM Series ESC with solder pads

$ 12.99

The new DYS XM20A V1 ESCs from DYS with the latest SiLabs F396 processor, these ESC were designed to handle the latest in high KV motors hitting the market. They capable of matching the speed of KISS ESC when using the new MultiShot firmware. The small size and integrated solder pads are much more beginner friendly and make for a cleaner and easier installation. No need to remove the heat-shrink and risk damaging components as with other ESC brands. Also makes it much easier than before to swap out motors.

These ESC come from the factory flashed with BLHeli OneShot125, but you can download and flash them with the latest MultiShot firmware using the DYS XM20A version of the hex file. The only difference between the 3 versions of the firmware (Fast March, Crazy Start, and Crazy Start) is the startup tone the ESC plays when powered up. Everyone likes Fast March. 

Some users on RCGroups have reported getting better performance flashing the XROTOR 20A version instead, with the ESC generating less heat as a result.

See the great review over at Oscar Liang's blog that goes into the details of this ESC and compares it against the new LittleBee 20amp PRO ones

MultiShot is so far only supported in latest BetaFlight or RaceFlight. To enable MultiShot use the following CLI commands:

  • BetaFlight (2.7.1 and higher): "set fast_pwm_protocol = MULTISHOT" and then "save".
  • RaceFlight: "feature multishot" and "save". You can also activate it on the configuration tab.

    • XM series ESC is the upgraded version of the SN series with advanced processor, a basic frequency up to 50MHz, and faster overall processing capacity to better support high KV motors
    • Designed for quick multi-rotor throttle response
    • Twisted pair cable is used to deliver throttle signal, reducing signal crosstalk while further stabilizing copper wire transmission
    • New miniaturization and ultra-low resistance MOSFET, powerful flow resistance, and professional MOS Drive chips improve efficiency
    • Newly designed PCB board improves impact resistance.
    • Sub-miniaturization design reduces weight while still providing a high performance filtering capacitor
