About This Game
Adds a 1000Hz software-in-the-loop bridge to Betaflight firmware. Replaces the built-in flight controller with the real firmware running on your PC, turning the simulator into a controlled environment for iterating on PID gains, filters, and rates without risking real hardware.
Detailed Description
This DLC adds a software-in-the-loop bridge between SITL Forge - FPV Laboratory and Betaflight firmware running on your PC. The built-in PID controller is replaced with the real firmware, so you fly and tune against the same code that runs on real hardware — driven by the simulator's 1000Hz physics model, calibrated against real bench measurements.
Requires the base app: SITL Forge - FPV Laboratory.
---
---
Iterate on PID gains, rates, filters, and rate profiles in a simulator that aims to approximate real airframe behavior as closely as possible — without risking hardware on every change. The behavior you see is driven by the same firmware code you'll flash to your drone, running against a physics model fitted to real bench data.
---
---
You provide your own Betaflight firmware build configured for software-in-the-loop. This DLC does not include or distribute Betaflight binaries. Build instructions are available in the Betaflight project's SITL documentation. In-app setup notes are also included.
---
This DLC is an independent integration. It is not affiliated with, endorsed by, or sponsored by the Betaflight project. "Betaflight" is a trademark of its respective owners and is referenced here only to identify the firmware this integration connects to.
Requires the base app: SITL Forge - FPV Laboratory.

What This DLC Adds
- 1000Hz PWM/FDM bridge — motor outputs and full physics state exchanged every millisecond
- 50Hz RC channel link — joystick or RC transmitter feeds the firmware's stick inputs
- MSP protocol over TCP — telemetry, blackbox, and configuration access
- MSP WebSocket bridge — connect a Configurator session straight to the firmware
- One-click mode switch — flip between built-in SIM and external firmware in-app

A Controlled Environment for Real Tuning
Iterate on PID gains, rates, filters, and rate profiles in a simulator that aims to approximate real airframe behavior as closely as possible — without risking hardware on every change. The behavior you see is driven by the same firmware code you'll flash to your drone, running against a physics model fitted to real bench data.
- Validate filter setups against simulated motor vibration
- Iterate on PID gains and feedforward without crashing real hardware
- Test rate profiles and stick feel before flashing
- Reproduce tricky tuning issues in a controlled environment
---
Technical Details
- UDP data link between simulator and firmware (ports configurable in-app)
- TCP MSP server for Configurator-style tooling
- Coordinate transform handled in-engine (Godot Y-up ↔ aviation NED)
- Per-axis vibration injection into the firmware's simulated IMU
