HDZero RACE V3 VTX Wiring
Unfortunately, the previous batches of HDZero VTX-R3 have different signal definitions for its connector, requiring users to re-pin it (see picture below) to match the correct connections. However, the latest HDZero Race v3 VTX features an updated connector that perfectly matches the Halo FC, enabling seamless plug-and-play installation.

Racing Stack
Here are two examples of how to mount the HDZero Race v3 VTX and the HDZero Halo stack in a racing drone. The configuration on the left fits a frame with 21.5 mm of clearance between the carbon plates, while the one on the right is suited for taller frames with a minimum clearance of 23 mm. To reduce space between FC and ESC, install the FC and ESC with plugs facing downward (note, this requires changing the order of the motors in Betaflight Motors tab).
ELRS Antennas Mount
Use the included antenna retainers—indicated by red circles below—to guide the antenna wires to the top plate and one of the arms. If space is limited, such as on compact racing drones, mounting only one antenna is acceptable.
