High-Performance Mini Power System for 3-5" Builds
The iFlight BLITZ Mini F722 Stack is a high-density power combo designed for modern freestyle and racing drones. Combining a lightning-fast F7 processor with a massive 55A ESC, this 20x20mm stack delivers "full-size" performance in a compact footprint.
Equipped with the STM32 F722 processor and the latest ICM42688 gyro, this FC handles high PID loop frequencies with ease. The improved circuit design significantly reduces electrical noise, providing a cleaner signal to your motors and VTX.
User Value: Smoother flight feel, ultra-low latency, and easier tuning even on high-KV racing setups.
BLITZ Mini E55S: 55A Continuous Power
Don't let the "Mini" tag fool you. The E55S ESC supports 2–6S input and provides a rock-solid 55A continuous current (65A Burst). With BB21 MCU and Bluejay firmware compatibility, it ensures a linear throttle response and precise motor synchronization.
User Value: Confidence to push high-pitch props on 6S without desyncs or burnt ESCs during aggressive power loops.
Plug-and-Play for DJI HD System
Say goodbye to tedious soldering. The integrated connector allows for a direct plug-in to your DJI O3 or Vista Air Unit. The FC also features 6 dedicated UARTs for GPS, telemetry, and external peripherals.
User Value: Reduces build time significantly and minimizes the risk of short circuits from soldering errors.
Visual Debugging & Blackbox Data
Equipped with 8MB onboard flash for Blackbox logging and visual LED indicators for power/status. These features allow you to diagnose flight issues at the field without a laptop.
User Value: Faster troubleshooting and precise PID tuning based on real flight data.
Lightweight & Built-Friendly Design
Weighing in at only 16.3g (total stack), the 20x20mm mounting pattern is optimized for tight freestyle frames and lightweight racing builds. The included silicon grommets provide excellent vibration dampening.
User Value: Keeps your build light for better power-to-weight ratio and protects delicate sensors from motor vibrations.

FAQFeel free to ask us any questions
Q: What size drone is this stack designed for?
A: With its 20x20mm mounting pattern and compact form factor, it is ideally suited for 3-inch to 5-inch mini drone frames.
Q: Does this stack support the DJI HD VTX system directly?
A: Yes, it does. Please note the integrated plug-and-play connector that allows you to connect your DJI HD VTX without any complex soldering.
Q: Is it "beginner-friendly" or will I burn it on the first flight?
A: It is user-friendly due to the connectors, but please note: high-power stacks require the included capacitor to be soldered correctly to prevent voltage spikes from frying the FC.
Q: Does it handle 6S batteries without overheating?
A: Yes, it is optimized for 2S–6S. Please enjoy the 55A continuous rating which handles the high-torque demands of 6S setups comfortably even during aggressive punch-outs.
Q: Why should I choose the F722 over a cheaper F405 stack?
A: The F722 processor is significantly faster and more future-proof. Please find that it handles complex filters (like RPM filtering) much better, resulting in a noticeably smoother and more "locked-in" flight feel.
