What is HDZero?
PUSH YOUR SKILLS TO THE LIMIT
HDZero offers industry-leading low latency, giving you more time to react and the best possible chance
of hitting that next gap. With its smooth, consistent FPV video feed, you’ll experience the same locked-
in feeling you get with analog video–but with the clarity of HD.
MAKE IT AN EVENT
HDZero supports the standard 5.8ghz video channels, meaning you can have up to 8 simultaneous pilots
flying either full-quality HDZero or analog video. When you’re ready to take a break and spectate, you
can tune in to any channel and view the pilot’s feed with no loss of quality, giving you the same feeling
of being in the air yourself.
UPGRADE YOUR FLEET
From 1S whoops to long-range wings, HDZero offers a variety of VTX and camera options to suit every
build. You may even be able to use the gear you already have–the HDZero receiver will work with any
FPV goggle with an HDMI input. HDZero can grow with your needs and fit perfectly into your preferred
FPV craft.
RAPIDLY EVOLVING SYSTEM
HDZero is rapidly evolving. Please always use the latest firmware that is located at www.hd-

Introduction
Designed in collaboration with racing pilots and MultiGP event coordinators, the HDZero Event VRX
makes it seamless to integrate HDZero into race DVR and live stream setups.
The Event VRX automatically switches between analog and HDZero video based on received video signal.
This means separate software is not needed to switch the recorded video between the two and no
special setup is needed ahead of time.
The Event VRX outputs both HDZero and analog video on HDMI and CVBS outputs. This means you can
use existing legacy analog video capture equipment such as an Owl DVR box or analog capture card,
keeping cost and complexity to a minimum.
The Event VRX packs four 2-antenna HDZero receivers into one enclosure, which reduces cost and
simplifies setup. The 2-antenna HDZero receivers have less noise rejection than full goggle VRX’s with 4
antennas, but still have excellent video reception for outdoor race events. 8 analog receivers are
included, setup in a diversity arrangement (2 analog receivers per channel).
