How to install LuaTelemetry on a Taranis X9D+?

Download the latest release from GitHub, copy the files to your transmitter's SD card under the SCRIPTS/TELEMETRY folder, and ensure OpenTX v2.2.3+ is installed. Refer to the Installation Instructions wiki for detailed steps.

LuaTelemetry vs Yaapu telemetry script: which is better?

LuaTelemetry offers more view modes and voice alerts, making it richer for situational awareness, but Yaapu might be simpler for basic telemetry. Choice depends on your need for features versus simplicity.

Does LuaTelemetry work with Betaflight 4.3?

Yes, it's compatible with Betaflight v4.0.0+, but note that some GPS and flight mode information will be missing, as mentioned in the README under Notes.

How to change the language to French in LuaTelemetry?

Voice files and interface languages are included; select the desired language in the configuration menu within the script, or replace voice files as per the Multilingual Support wiki.

Why isn't my GPS data displaying in LuaTelemetry?

Ensure you have a compatible GPS module like the Beitian BN-880, and that it's properly connected and configured in INAV/Betaflight. Check the Setup and Tips wiki for common problems.

Can I use LuaTelemetry with a Jumper T18 transmitter?

The README lists support for Jumper T12 and T16; for T18, check if JumperTX is compatible or if community ports exist, as it's not explicitly mentioned.

What is LuaTelemetry?

LuaTelemetry is a Lua script that displays real-time flight telemetry data from INAV or Betaflight flight controllers on compatible RC transmitters. It provides pilots with critical information like battery status, altitude, speed, GPS location, and orientation through multiple visual views and voice alerts, directly on their transmitter screen.

Target Audience

FPV and RC pilots using INAV or Betaflight flight controllers with FrSky, TBS Crossfire, or compatible telemetry systems, who want enhanced situational awareness without relying solely on OSD or external ground stations.

Value Proposition

It offers a feature-rich, customizable telemetry display with multiple view modes and voice alerts, all running locally on the transmitter for low-latency feedback, and supports a wide range of popular hardware without requiring additional hardware.

Overview

FrSky SmartPort(S.Port), D-series, F.Port and TBS Crossfire telemetry on all Taranis and Horus transmitters

Use Cases

Best For

FPV pilots needing real-time battery and GPS telemetry on their transmitter

Not Ideal For

Pilots using flight controllers with firmware other than INAV or Betaflight (e.g., ArduPilot or KISS)
Transmitter users with models not explicitly supported, such as older FrSky or non-listed brands
Scenarios requiring simultaneous use of multiple Lua scripts on memory-constrained transmitters
Newcomers to FPV telemetry who want plug-and-play setups without Lua script configuration

Pros & Cons

Pros

Multi-View Display Options

Offers classic, pilot, radar, and altitude graph views, providing flexible visual interfaces for different flying conditions, as shown in the README screenshots.

Wide Hardware Compatibility

Supports a broad range of FrSky and TBS Crossfire receivers, and transmitters like Taranis, Horus, Jumper, and FLYSKY Nirvana, detailed in the Features section.

Real-Time Voice Notifications

Provides spoken alerts for critical events such as low battery, altitude warnings, and arming status, enhancing pilot awareness without visual clutter.

Telemetry Log Playback

Allows playback of previous flights with controls like play, pause, and rewind, useful for post-flight analysis and review, as mentioned in the Features.

Cons

Limited Betaflight Functionality

When used with Betaflight, some GPS and flight mode data is missing, reducing telemetry completeness compared to INAV, as noted in the Notes section.

Crossfire Telemetry Deficiencies

TBS Crossfire receivers lack support for HDOP, GPS altitude, and certain flight mode notifications, limiting data availability in those setups.

Transmitter Memory Constraints

On some transmitters, limited memory can prevent running other Lua scripts simultaneously, such as VTx control scripts, affecting multi-functionality.

PID-Analyzer

PID-Analyzer is a Python-based tool that reads Betaflight blackbox logs and calculates PID step responses to provide a systematic approach to tuning quadcopter flight controllers. It helps pilots visualize how their PID settings affect flight performance by mathematically deriving the system response from input (PID commands) and output (gyro data). ## Key Features - **Blackbox Log Analysis** — Reads Betaflight blackbox logs using blackbox_decode.exe to extract flight data. - **PID Step Response Calculation** — Computes the system response via deconvolution to evaluate PID performance. - **Weighted Response Functions** — Reduces impact of external disturbances (e.g., wind) by weighting responses based on RC-input and quality. - **Dual Response for High Inputs** — Calculates separate responses for inputs above and below 500 deg/s when D Setpoint Transition is enabled. - **Throttle and TPA Visualization** — Plots throttle and TPA thresholds to account for dynamic PID changes during aggressive maneuvers. - **Cross-Platform Support** — Tested on Windows 7/10 and macOS 10.10 with Betaflight 3.15/3.2/3.3 logs. ## Philosophy PID-Analyzer aims to replace guesswork in PID tuning with a data-driven, mathematical approach, making it easier for pilots to achieve stable and responsive flight characteristics.
