SEQURE Blueson A2 70A 8S AM32 4-in-1 ESC (30×30)

The Sequre Blueson A2 is a heavy-duty 4-in-1 ESC engineered for demanding 7-inch long-range rigs, macroquads, and heavy-lift cinelifters. Delivering 70A of continuous current per motor and supporting up to 8S LiPo power, it provides the electrical overhead required for large-stator motors swinging heavy payloads without overheating.

Key features

• Pre-flashed with open-source AM32 firmware, supporting up to 128KHz PWM frequency for precise low-end motor control and reduced desync risk.

• 70A continuous current rating per channel handles aggressive throttle spikes on large props and heavy builds.

• Native 8S LiPo compatibility allows builders to run high-voltage setups for lower current draw and cooler electronics.

• Standardised 30.5x30.5mm stack footprint for straightforward integration into mid-to-large FPV frames.
