NeuiFlight BLITZ Mini ATF435 Stack 55A 2-6S FPV-Flugcontroller mit Regler
The iFlight BLITZ Mini ATF435 Stack is a compact high-performance FPV stack built for pilots who want strong power handling, clean wiring, and reliable tuning support in a mini form factor. Combining an AT32F435 flight controller with a 55A 2-6S 4-in-1 ESC, this stack is a great choice for freestyle, racing, and advanced DIY drone builds where space is limited but performance still matters.
Whether you are building a lightweight 3-inch freestyle quad, a powerful 3.5-inch setup, or a compact 5-inch performance drone, this stack gives you the control response, current headroom, and tuning flexibility needed for modern FPV flying.
The iFlight BLITZ Mini ATF435 Stack combines an AT32F435 flight controller with a 55A 4-in-1 ESC, giving compact FPV drones the power and control usually expected from larger stacks. Designed in a 20x20 mini FPV stack format, it is a strong fit for 3 to 5 inch freestyle drones, racing drones, and performance-focused DIY builds.
Built around the AT32F435RGT7 MCU, this FPV flight controller also features a BMI270 gyro and DPS310 barometer for fast processing and stable signal handling. Compared with more basic FC setups, it gives pilots a cleaner control foundation for demanding freestyle and racing use.
User value: smoother flight response, more precise tuning, and a more locked-in control feel.
The E55S Mini 4-in-1 ESC supports 2-6S LiPo input with 55A continuous and 65A burst output, making it a reliable choice for aggressive throttle changes, higher KV motors, and heavier prop loads. This gives the stack the current headroom needed for more demanding FPV builds.
User value: stable power delivery, stronger punch-outs, and more confidence during hard freestyle moves or race acceleration.
With 6 UARTs, 16MB blackbox, and support for SmartAudio and IRC Tramp, this FPV stack gives pilots more room for tuning, telemetry, and VTX control than basic mini stacks. It is better prepared for GPS, receivers, video transmitters, buzzers, and other accessories used in modern custom builds.
User value: more control, cleaner wiring options, and better data for tuning and optimization.
Designed with a 20x20 mounting pattern, a compact 30.5 x 27mm FC size, and total weight under 20g, this mini drone stack fits tight frames without giving up key performance features. It is ideal for lightweight freestyle drones and compact racing builds where space and weight both matter.
User value: easier installation, cleaner layouts, and better fit for small high-performance builds.
The BLITZ Mini ATF435 Stack supports DShot150/300/600, MultiShot, OneShot, BLHeli_S, and Bluejay, and uses the IFLIGHT_BLITZ_ATF435 firmware target for easier setup. With support for common FPV protocols and accessories, it integrates smoothly into many modern freestyle and racing drone builds.
User value: less setup hassle, faster configuration, and easier matching with popular FPV components.
