HDZero Race V3 Video Transmitter
Designed for FPV racing, the HDZero Race V3 VTX is our 3rd generation digital video transmitter. With a voltage
range starting at 4V, it can be powered by the 5V 1.5A regulator of most FC’s or up to 12V for FC’s that include a
HD VTX plug. It is small (28x32x5mm) and light (5.5 grams). With a width of only 28mm, the VTX is now a similar
width to many FC's, which improves durability and reduces weight. The antenna is securely attached with a metal
bar and screws. No soldering needed – just plug the wire harness into a compatible HD-ready FC.
The HDZero Race V3 VTX is designed with durability in mind, rather than weight. It is made with a 1.6mm thick
PCB, in comparison to the 1.0mm PCB used in the Whoop lite VTX. Moreover, it uses more large package size
components for stability consideration. For the smaller components, an additional glue coating is applied to
increase crash protection.
The HDZero Race V3 VTX offers high-quality video in 540p90, 720p60 and 1080p30 resolutions with 25/200mW
switchable power on 5.8GHz.
