T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack
Extreme power and stability in every second of flight thanks to T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack
The T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack is a professional power and control solution designed with modern FPV drones in mind. With full support for up to 8S voltage, the stack provides an incredible power reserve and operational stability even at maximum throttle opening. The multi-layer PCB design effectively dissipates heat, reducing electrical stress on the components. A built-in Bluetooth module and a modern ICM-42688P gyroscope guarantee lightning-fast configuration and remarkably smooth drone responses to stick movements. It is an uncompromising choice for any pilot.
Intuitive Plug-in signal installation in
T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack
Assembly and servicing of the electronics become extremely simple thanks to the use of a Full Plug-in Design for all signal connections in the T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack. All wiring connecting the flight controller (FC) to the electronic speed controller (ESC) strictly follows plug standards compatible with the BF. This eliminates the need for complicated and time-consuming soldering of tiny signal wires, drastically reducing the risk of error and keeping platform build time to a minimum.

Optimized 70A Multi-Layer PCB
The ESC features an optimized multi-layer PCB designed to handle 70A continuous current. Thickened copper power layers eliminate energy distribution bottlenecks, allowing high current to flow freely without the risk of overheating. This maximizes the FPV drone's overall efficiency and reliability under sustained heavy loads.
Unmatched 8S Power Reserve
The innovative design of the T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack officially supports 8S battery packs. This upgrade boosts burst thrust and efficiency by up to 50%, radically transforming freestyle flight dynamics. Additionally, the higher voltage headroom guarantees safe and stable electronics operation during extreme throttle inputs.
Upgraded 3rd Gen BEC System
The integrated 3rd generation BEC power system reduces ripple voltage by 50%. Delivering perfectly clean current drastically minimizes electrical interference reaching the gyro, ensuring more precise sensor readings and flawless noise filtering by the flight controller.
