BLITZ Mini ATF435 Stack (E55S Mini 4-IN-1 ESC)

Experience next-level performance with the latest iFlight BLITZ Stack, designed for reliability, precision, and seamless integration in your build.

Flight Controller (FC)

Powered by an ultra-fastATF435 MCU, the BLITZ Mini F7 Flight Controller delivers responsive control and stable flight performance on 26S LiPo setups. Featuring an improved circuit design and high-quality components, it ensures low electrical noise and enhanced durability. A built-in DJI HD VTX plug-and-play connector removes the need for soldering, while LED indicators and an integrated LC filter simplify setup and troubleshooting. The 20x20mm mounting pattern makes it the perfect fit for modern freestyle and racing frames.

Electronic Speed Controller (ESC)

The latestBLITZ Mini E55 4-in-1 ESC pushes performance boundaries with 55A continuous current on 26S batteries, ideal for even the most power-hungry motors. Running BLHeli_S firmware (BlueJay), it ensures smooth throttle response and precise motor control. Engineered for efficiency and reliability, this ESC perfectly complements the BLITZ Flight Controller and fits the same 20x20mm mounting pattern, offering a clean, compact stack solution.
