Swappable Elements

Injected Loveliness

No milled carbon, 3d printing, or bent aluminium in sight. The LZR Mini is a full-custom, injected plastic design, which matches the Dominator goggles perfectly.

The single M3 mounting screw allows the antenna array to swivel upwards for pilots who tend to watch their feet while flying, and lie flat for zipper case storage.

rapidFIRE Integration

The twin RSSI bars (especially the full-width version) may be used to aim the antenna.

The latest rapidFIRE firmware augments the RSSI bars with audible feedback, allowing An upcoming firmware update (v1.3.0) will augment this with audible feedback, allowing a long-range pilot to keep eyes on the target, and not the OSD.
