DYS multicopter parts

Take advantage of the latest BLHeli_S development with these DShot capable ESC’s. The DYS XSD series speed controllers (ESC) have been designed for high-speed motors, which make them ideal for racing drones. The ESCs utilise a high-performance Silads EFM8BB21 microprocessor for smooth response and high-resolution throttle steps. They also come with BLHeliS firmware pre-flashed and support DShot300 or DShot600. Firmware can be upgraded by signal wire using USB Linker.

The 20A and 30A versions include a plastic case to protect the ESC against prop strikes and all of the ESCs have solder pads which make it easy to quickly swap out motors during field repairs!
