FPV Assistant
Tell it what’s wrong with your drone, paste a diff or drop in a Blackbox log: it tells you what’s happening, why and how to fix it. It can also connect to the drone over USB.
Don’t have your drone to hand? A virtual drone responds like a real one: connection, setup, CLI, firmware and backups, with no risk.

What it can do
A workshop mate who understands Betaflight
Diagnosis
Tell it what’s happening
Oscillations, hot motors, propwash, jello, drift, failsafes… It gives you the most likely causes, what to check and the commands to fix it.
Blackbox
Analyse logs like a pro
Step response, noise before and after the filters with motor harmonics, a throttle × frequency map, comparison between flights and a downloadable report. With chirp logs, the frequency response and the sensitivity peak.
CLI
Review and update your configuration
Analyse a diff, spot parameters that no longer exist, convert it between 4.3, 4.4, 4.5, 2025.12 and 2026.6, compare two of them and look up any parameter with its range.
Live
Connect the drone over USB
From Chrome or Edge: real-time status and reasons it won’t arm, channel map detection, switch assignment and applying changes with confirmation.
Firmware
Install Betaflight and keep backups
Step by step: back up the configuration to the hangar, firmware built with your board’s options, install over USB (DFU), recovery of boards that won’t boot and restore of the configuration, adapted if you change version.
Everything runs in your browser: logs and configurations aren’t sent anywhere. Only the list of presets and the firmware are requested from Betaflight’s public services when you use them. The data for each Betaflight version (parameters, ranges, flags and modes) has been extracted from the official source code.
