GEP-STABLE V2 F4 30A stack

The GEPRC GEP-STABLE V2 F4 30A Stack is a highly integrated, compact, and powerful 20x20mm electronics system designed for micro, racing, and freestyle FPV drones. This triple-layer flight tower combines an F4 flight controller, a 30A 4-in-1 ESC, and a switchable 5.8GHz video transmitter (VTX) into a neat, space-saving format.

Driven by an STM32F405 processor and a reliable MPU6000 gyroscope, this mini stack simplifies wiring, minimizes overall weight, and runs popular firmware versions like Betaflight and iNav to ensure steady and precise flight control.

Features

High-performance STM32F405 processing core paired with a proven MPU6000 gyro

Space-saving 20x20mm triple-layer design ideal for tight micro and racing frame layouts

Integrated Betaflight OSD to monitor battery levels, signal status, and altitude directly on the video feed

Built-in LC filter to clear up power distribution and shield components from video noise

Includes a stacked 5.8GHz 48-channel VTX supporting up to 600mW output power and IRC Tramp control

Innovative soft-mounting silicone isolation to reduce vibration transfers to the gyro sensor
