T-Motor V70A ESC & F7 FC SE 6-8S 4IN1 Stack

The T-HOBBY Velox V70A F7 SE 8S FPV Stack is a high-performance power and control solution designed for demanding FPV pilots who require reliability, clean power delivery, and future-ready 8S support.

Built around a 70A continuous 4-in-1 ESC and a powerful F7 flight controller, this stack is optimized for freestyle, cinematic, and high-power FPV builds. The upgraded 8S voltage input provides greater electrical headroom, helping maintain stable performance under aggressive throttle and heavy load conditions.

An optimized multi-layer PCB design significantly improves current-carrying capability while reducing heat and electrical stress. Combined with a third-generation BEC, the stack delivers cleaner power to sensitive components, resulting in reduced gyro noise and more consistent flight performance.

The Velox stack features a full plug-in design following Betaflight standards, allowing for fast, clean, and reliable installation between the FC and ESC. With built-in Bluetooth and onboard Blackbox, pilots can easily tune, configure, and analyze flight data without additional hardware.

Designed with durability, safety, and performance in mind, the Velox V70A F7 SE 8S FPV Stack is an ideal choice for pilots upgrading from 6S systems or building next-generation high-power FPV drones
