The HDZero Gamma is a compact, high-performance flight controller built around the G473 MCU, delivering powerful computational capability. It comes with an integrated 2.4GHz ELRS receiver and dual BEC outputs-an 8V/3A line for video transmitters and a 5V/3A line for LEDs and peripherals-streamlining quad assembly by reducing external components.
8+
9+
At its core, the Gamma features a 4-in-1 ESC engineered to deliver exceptionally clean power to the MCU, shielding it from voltage spikes caused by rapid motor acceleration or deceleration. This protection minimizes the risk of brownouts or lockups, which are often responsible for burnt motors, failed MOSFETs, and catastrophic flight failures. Each motor is capable of sustaining 45A for 30 seconds, with peak bursts reaching 60A.
10+
11+
Purpose-built for drone soccer and digital FPV systems, the Gamma eliminates the analog OSD chip to save space and reduce costs. Optimized for pairing with the HDZero Whoop v2 VTX, it enables a low-profile stack ideal for competitive and lightweight builds.
