FlightHUD

Fullscreen telemetry widget for EdgeTX 2.12+ color-screen radios (reference layout: 800x480, RadioMaster TX16S MK3). Built as a standard overview widget for LOS models with mixed FrSky / ExpressLRS receivers.

Features

• Battery: total voltage, per-cell voltage (auto cell-count detection), min/max, 0-100% charge bar
• Current (live + max), mAh consumed
• RPM (live + max), speed (live + max)
• Timer 1
• Link quality with color-coded thresholds and min-LQ; dBm/ELRS RF mode/TX power shown automatically when present
• Header: model name (left), flight mode (centered), TX battery voltage + clock (right)
• Missing/unconfigured sensors show --- instead of erroring
• Automatically switches to a compact layout on 480-wide radios

Install

Download the ZIP attached to the latest GitHub release, extract it, and copy the included WIDGETS folder to the root of the radio's SD card. The repository and release ZIP already use the same EdgeTX-ready layout:

• /WIDGETS/FlightHUD/main.lua
• /WIDGETS/FlightHUD/app.lua

Add FlightHUD as a fullscreen widget on a Main View screen (1x1 layout).

Options

Each of the six main values has its own Source picker in the widget's settings screen (long-press the widget -> Configure widget), just like any other EdgeTX source field - pick the exact sensor from the standard list instead of relying on name-guessing:

• Battery Voltage, Current, mAh Consumed, RPM, Speed, Link Quality: pick any matching sensor on the model (defaults to a sensible guess - Cels/VFAS/RxBt/A1/A2 for voltage, Curr/Iavg for current, etc. - but always overridable)
• Cell Count: Auto-detect or manual 1S-14S
• Theme: Dark or high-contrast

dBm, ELRS RF mode, and TX power are not user-selectable - they're auto-discovered by name (1RSS/TRSS, RFMD, TPWR) and simply omitted from the LINK card when not present, since they're auxiliary readouts rather than flight-critical values.

Notes

• Auto cell-count detection is exact when using a per-cell Cels sensor. With total-voltage sensors (VFAS, RxBt, A1, A2), set Cell Count manually if you power the model from a partially discharged pack. Once locked, the detected count is also treated as plausible after a voltage sag (e.g. under load) so it doesn't flip mid-flight.
• RFMD is decoded using the official ExpressLRS 4.x mapping, including 28 -> 333Hz Full on 2.4GHz. Unknown values are shown as Mode N so a newer or unsupported firmware mode remains visible.
