BLITZ ATF435

Positive Spin

✓ BLITZ ATF435 — high-performance flight controller with ample UARTs and Betaflight support.

Reasoning

Across sources, the Nazgul Eco's flight controller is consistently referred to as BLITZ ATF435 (or ATF435 variants), with multiple mentions of the six UARTs and Betaflight support. Alternative references to AT32 are less consistent. Therefore, BLITZ ATF435 is the most accurate and commonly used canonical term.
