iFlight BLITZ ATF435 E55S 4-IN-1 Stack
The iFlight BLITZ ATF435 stack consists of an AT32 flight controller and an E55S 4-in-1 55A ESC.
Powerful FC/ESC combination with AT32F435 and 55 A ESC. Tuned for efficient, modern FPV builds.
The ATF435 flight controller is based on the AT32F435 MCU from ArteryTek - a powerful, cost-efficient alternative to the F7 series. Equipped with OSD, barometer, 32 MB black box and dual BEC (5 V & 9 V), it delivers everything that advanced FPV setups require. It is complemented by the BLITZ E55S 4-in-1 ESC, which is an ideal addition with 55 A continuous current and only 14.7 g weight. Thanks to the 30.5 × 30.5 mm standard mounting, the stack fits perfectly with Nazgul F-series quads and many other builds.
