Take advantage of the latest BLHeli_S development with these DShot capable ESCs. 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 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!
Features:
- Utilizes high-performance EFM8BB2 50MHz MCU
- 12 FET Design
- High-current burst rating
- High-Resolution Throttle steps
- Supports Dshot600, Dshot300 – faster than Oneshot
- Dshot ESCs don’t require an ESC calibration
- Firmware upgradable via signal wire (works with USB Linker for XM series)
- Supports Motors with super high KV (EFM8BusyBee 50MHz can handle up to 500k eRPM)

Questions and answers of the customers

Here at Flying Tech we have a wide choice of electronic speed controllers (ESCs).
There are two main types of ESCs: 4-in-1 ESCs and single ESCs. A 4-in-1 ESC integrates four individual ESCs onto a single circuit board, each controlling a separate motor. A single ESC controls only one motor.
This 4-in-1 ESC is a more popular choice for racing quads, while single motor aircraft such as fixed wings would use a single ESC. Single ESCs are still used by some drone racers though, as after a crash or a burnt up ESC, they only have to replace one, not an entire 4-in-1 or stack which is a lot more costly. Single ESCs are also available which much greater current ratings (80amp +) so they are also used by power hungry multi-rotors, for example X-Class racing quads, professional camera flying “Cinelifters”.
When using individual ESCs, they typically need to be connected to a single power distribution board (PDB) or an “AIO flight controller” (a type of flight controller with integrated PDB) for power supply.
