Sequre Blueson A2 65A 6S / 70A 8S 128K 4-In-1 ESC (AM32 Firmware)
Price range: £29.99 through £44.99 Inc. VAT
High-performance 4-in-1 ESC with AM32 firmware, oblique pads, and 6S or 8S options—at an unbeatable price.
The SEQURE Blueson A2 4-in-1 ESC delivers impressive performance at a price that’s hard to beat, with two versions available: a 65A model for 6S setups, and a 70A model for up to 8S builds.
Designed for high-performance builds, the Blueson A2 uses a robust multi-layer PCB with thick copper to improve current handling and heat dissipation. It features high-quality MOSFETs and comes pre-flashed with AM32 firmware for smooth, precise motor control at PWM frequencies up to 128KHz. It’s compatible with DShot, PWM, OneShot, and other common protocols, ensuring flexibility with different flight controllers.
Each channel can handle a continuous 65A on 6S or 70A on 8S, with ample headroom for bursts—ideal for powerful freestyle quads, long-range cruisers, or heavy-lift setups.
Standard 30.5mm x 30.5mm mounting makes it easy to fit into most frames, and oblique motor soldering pads align naturally with frame arms, making motor wire installation cleaner and more accessible—ideal for tidy builds and easier maintenance. A connector interface is also included for clean integration with your flight controller.
Combining solid specs, thoughtful layout, and exceptional value, the Blueson A2 is a reliable, budget-friendly option for serious FPV pilots.
