iFlight BLITZ Stack – F7 V1.2 FC + E55 4-in-1 55A ESC

The iFlight BLITZ Stack pairs the F7 V1.2 flight controller with the E55 4-in-1 55A ESC, a 30.5x30.5mm all-in-one core for 5-inch freestyle, racing and long-range builds running 2-6S LiPo.

Key features

• STM32F722 processor with an ICM42688 gyro and DPS310 barometer for stable, low-noise flight performance.
• Plug-and-play DJI HD VTX connector needs no soldering, powered by dual BECs at 5V/2.5A and 9V/2A.
• Six full hardware UARTs leave room for GPS, receiver, telemetry and VTX without sharing ports.
• 32MB onboard blackbox flash logs extended, high-resolution data for PID tuning.
• E55 ESC delivers 55A continuous current (65A burst) with an onboard current sensor.

A wiring harness and silicone grommet set are included, so the stack drops straight into a standard 30.5x30.5mm build for 5-inch freestyle or long-range frames. On 7-10 inch builds, fit an additional external capacitor to avoid overloading the ESC's onboard capacitor.
