HGLRC Zeus Nano VTX 350mW Analog Video Transmitter, 25.5x25.5mm

The HGLRC Zeus Nano VTX fills the smaller end of HGLRC's video transmitter range, putting 350mW of analog FPV output into a nano-size board built to mount on tight 25.5x25.5mm stacks as well as the smaller 1616 and 2020 hole patterns found on micro quads. It is aimed at builds where a full-size 2.5W VTX like the Zeus is simply too large or heavy, while still giving more range than a bare whoop-class transmitter.

At 350mW, it sits comfortably within most regional power limits for everyday flying without needing to switch into a lower mode, and HGLRC positions it as suited to both small and larger builds where reliable, straightforward video transmission matters more than maximum range. The compact board size is the main selling point here: fitting a 25.5x25.5mm or smaller stack means it slots into freestyle and whoop-class frames that a larger 30.5x30.5mm VTX simply will not clear.

In the box, HGLRC includes an IPEX linear brass antenna along with an IPEX-to-SMA adapter cable, so the transmitter can run its stock linear antenna close in or be adapted to a larger SMA-mount cloverleaf or patch antenna when more range or better polarization is wanted. Six VTX cables are also included, covering the common wiring variations found across different flight controller and stack layouts, which saves hunting for the right connector on a build day.

Builders working on a small freestyle quad, a 3-inch or smaller cinewhoop, or any frame where a full-size VTX won't physically fit will find the Zeus Nano a sensible match. For long-range work or anything needing more than 350mW, the larger Zeus VTX 2.5W is the better pick.
