Live CRSF telemetry
Plug your radio over USB and stream telemetry in real time — RSSI, link quality, battery, GPS, attitude.
FPV · Telemetry · Flight logs
Every flight, recorded.
Live CRSF telemetry over USB, Betaflight blackbox import, and a hangar that remembers every drone you fly. Built for pilots who want signal, not noise.
Join the GhostTrace community on Discord What it does
Built around the way pilots actually fly.
Betaflight blackbox import
Drop your .bbl logs. GhostTrace parses, indexes, and turns them into replayable sessions.
Drone hangar
Track every build: motor count, battery cells, frame. Stats roll up per drone automatically.
Map replay & charts
Replay flights on an OpenStreetMap track with synced telemetry charts. See exactly where the signal dipped.
Pilot stats
Total flight time, distance, max speed, max altitude — across every drone you own.
Find your lost drone
Last known GPS position is saved automatically. If you crash out of sight, GhostTrace guides you to the spot with bearing, distance and a compass.
A look inside
Designed to read at a glance.
Telemetry HUD, session replay and drone hangar.
FAQ
Radio compatibility
Live USB recording depends on your radio firmware and your RC link. Blackbox import works with everything.
Which radios can record live over USB?
| Radio | Firmware | Live USB | BLE bridge |
|---|---|---|---|
| Any EdgeTX radio (RadioMaster, Jumper, FrSky…) | EdgeTX 2.7+ | ✓ | ✓ |
| Jumper T16/T18, RadioMaster TX16S, FrSky Horus X10/X12S | OpenTX 2.3.15 | ✓ | ✓ |
| Other OpenTX radios (Taranis X9D, Q X7…) | OpenTX (any version) | ✗ | ✓ |
| TBS Tango 2 / Mambo | FreedomTX | ✗ | ✗ |
Live telemetry needs an ELRS or Crossfire module (CRSF). BLE bridge: works with any radio firmware via the ESPNOW backpack of an ELRS module (ELRS 3.4+). Blackbox import works with every radio.
Do I have to switch from OpenTX to EdgeTX?
Not necessarily. On a Jumper T16/T18, TX16S or Horus, updating to OpenTX 2.3.15 is enough — your models and settings stay untouched. Then pick USB Mode → “Telem” when plugging the cable. Other OpenTX radios (Taranis X9D, Q X7, …) do need EdgeTX for USB telemetry.
Is the TBS Tango 2 or Mambo supported?
Live recording is not possible: their FreedomTX firmware has no USB telemetry mode, and EdgeTX never supported these radios. Blackbox import works normally.
Do I need an ELRS or Crossfire module?
Yes, for live telemetry: the app decodes CRSF, the protocol used by ExpressLRS and TBS Crossfire/Tracer. FrSky, Flysky or DJI links do not produce a CRSF stream, regardless of the radio firmware.
My radio cannot stream over USB — any other option?
Yes: the GhostTrace BLE bridge, a small USB-powered ESP32 that receives the telemetry your ELRS backpack broadcasts (Backpack ON, Telemetry = ESPNOW) and re-emits it over Bluetooth — it needs an ELRS module with backpack support, whatever the radio firmware. And blackbox import (.bbl/.csv from the flight controller) works with every radio: flights, charts, GPS replay and stats need no live link at all.
