T-Motor Velox F7 SE 8S+V70A SE Stack AM32 8S 4IN1 Stack

T-Hobby Velox F7 SE 8S + V70A SE 8S 4-in-1 ESC Stack

Extreme 8S Power. Open-Source AM32 Control.

The T-Hobby Velox F7 SE 8S + V70A SE Stack is a heavy-duty, high-voltage powerhouse engineered to push the boundaries of modern FPV performance. Upgraded with native support for up to 8S battery input, this combo unlocks up to a 50% increase in maximum thrust while delivering a massive electrical headroom threshold for safer operations under high load. Designed with unified plug-and-play wiring following strict Betaflight socket standards, it streamlines clean layout integration while preventing incorrect wire positioning.

At the core of the stack is the high-velocity STM32F722 processor paired with an ICM-42688-P gyro via high-speed SPI. The flight controller integrates a huge 128MB onboard flash Blackbox chip—providing eight times the storage capacity of standard budget boards—allowing pilots to record extensive flight log streams without constant clearing. Power stability is managed by a third-generation dual BEC circuit that slashes ripple voltage by 50% compared to previous designs, filtering electrical noise up to 90dB to provide clean, low-latency data straight to your gyroscope.

The companion 4-in-1 V70A SE ESC runs open-source AM32 firmware on an upgraded 32-bit chip architecture to sustain an enormous 70A continuous current. Built on an optimized multi-layer PCB layout that limits structural resistance and maximizes thermal dissipation, it provides stable performance across high-stress racing and long-range tracking lines. Whether assembling an aggressive 5-inch freestyle weapon or a heavy 10-inch long-range cinematic lifter, the Velox 8S stack delivers incredible headroom.
