iFlight BLITZ ATF435+BLITZ E55S FPV Stack

Propel your FPV flying to new heights with the iFlight BLITZ ATF435+E55S Tower System. This powerhouse duo integrates the advanced iFlight BLITZ ATF435 flight controller with the robust BLITZ E55S ESC, providing a seamless blend of next-generation performance, durability, and control for your 5-inch freestyle or racing drone.

Next-Generation AT32 Processing Power

At the core of this stack is the Blitz ATF435 flight controller, featuring a cutting-edge ArteryTek AT32F435 processor. This advanced MCU often runs at higher clock speeds than traditional F7s, providing an incredible amount of processing headroom for Betaflight’s most demanding features. Paired with the modern, low-noise BMI270 gyro and a high-precision DPS310 barometer, this FC delivers an exceptionally smooth, responsive, and locked-in flight experience.

Powerful & Feature-Rich ESC

The included Blitz E55S 4-in-1 ESC is built to handle aggressive flying, delivering a massive 55A of continuous current (65A burst) on up to 6S LiPo. While it comes on reliable BLHeli_S hardware, it is fully compatible with Bluejay firmware, which unlocks modern features like bi-directional DShot for RPM filtering, giving you top-tier performance without the cost of a full BLHeli_32 ESC.

Key Features:

• Advanced AT32F435 MCU: Delivers exceptional processing power for the smoothest, most responsive flight experience with all modern Betaflight features enabled.
• High-Performance BMI270 Gyro: A modern, low-noise gyro providing the clean data needed for a locked-in feel and easier tuning.
• Robust 55A 4-in-1 ESC: Provides plenty of reliable power for aggressive freestyle and racing, with a 65A burst rating for peace of mind.
• Bluejay Firmware Compatible: Unlocks modern features like bidirectional DShot and RPM filtering on the reliable BLHeli_S hardware platform.
• Dedicated 9V BEC for Digital FPV: A powerful 9V/2A BEC and dedicated port make installing a DJI Air Unit or other HD systems simple and reliable.
• Large 32MB Blackbox: Ample storage for detailed flight logs, essential for professional-level tuning and diagnostics.
