Power your FPV drone with the DYS XS30A, a high-performance 30A individual ESC known for its incredible reliability and smooth operation. This ESC is an essential component for any high-performance build, utilizing the fast EFM8BB2 50MHz MCU and proven BLHeli_S firmware to deliver a locked-in and responsive flight experience.1
Smooth & Quiet Operation
The XS30A features hardware-generated PWM that is synchronous to the MCU, resulting in ultra-quiet and remarkably smooth motor performance.2 This advanced design, combined with the 50MHz MCU, can handle high-KV motors (up to 500,000 eRPM) and provides the high-resolution throttle steps needed for precise control, from cinematic pans to full-throttle racing.3
Durable Arm-Mounted Design
As an individual ESC, the XS30A is perfect for FPV drone builds that use arm-mounted electronics, a popular choice for durability and easy field repairs. This ESC includes a fitted protective case, shielding it from prop strikes, debris, and crash damage—a major advantage for pilots who fly hard 4
