SEQURE H743 V2 & E70 G2 Stack (ICM42688P + 70A 128K AM32 Power Stack)

The SEQURE H743 V2 & E70 G2 combo is the “I’m done rebuilding mid-season” stack for racers, freestyle fanatics, and long-range pilots who insist on flying like they’re filming the DRL finals. With a 480 MHz H7 brain, premium ICM42688P gyro, and a 70A 4-in-1 ESC that shrugs at 8S, this stack keeps your quad locked in even when your thumbs aren’t. SEO tribute: H743 flight controller, 70A FPV ESC, AM32 stack.

Why You Want It

Because you want clean gyro data, punchy throttle, and fewer “why did it desync?” post-crash therapy sessions. The H743 V2 brings dual-BEC convenience for O3/O4 and analog VTX, full X8 motor support, and actual log space (16 MB!) for tuning obsessives. Pair that with the E70 G2’s 128 kHz PWM smoothness, massive MOSFETs, and real telemetry, and you’ve got a stack that flies stable, hits hard, and forgives the occasional Bardwell-inspired tree kiss. (Existential shrug: no FC can fix bad rates.)

Specifications

• FC Processor: STM32H743 @ 480 MHz (fast enough to judge your PID choices)

Still Here?

You’re either speccing a dream build or procrastinating soldering. Either way, this H743 & 70A AM32 stack is ideal for high-power 8S racing and freestyle frames that demand clean gyro data and ESC response that doesn’t flinch. Share it with a mate — or claim it before they do.
