The SEQURE Blueson A1 4-in-1 ESC offers outstanding performance and reliability for demanding FPV builds, with two current ratings available: 65A for 6S setups and 70A for up to 8S builds.
Built on a compact multi-layer PCB with thick copper traces, the Blueson A1 is designed to handle high current while keeping heat under control. It uses quality MOSFETs and comes pre-flashed with AM32 firmware, supporting PWM frequencies up to 128KHz for smooth, responsive throttle control. It’s also compatible with BLHeli_32 variants and works with DShot, PWM, OneShot, and other common protocols, ensuring easy integration with a wide range of flight controllers.
Each channel can deliver a continuous 65A on 6S or 70A on 8S, with plenty of overhead for short bursts, making it well-suited to powerful freestyle quads, long-range cruisers, or heavy-lift drones.
The A1 uses a 20 x 20mm mounting pattern, making it ideal for modern, compact builds. Large motor solder pads make installation straightforward, while the included connector interface provides the option of a clean plug-and-play connection to your flight controller. Accessories such as an XT60 pigtail, capacitor and anti-vibration grommets are included to help complete the installation.
With its strong specifications, firmware flexibility and thoughtful design, the Blueson A1 is an excellent choice for pilots who want a compact, high-power 4-in-1 ESC at great value.
