NexusFlight Suite
Flight controller firmware that adapts to how you fly
Less propwash. Handles wind without retuning. Consistent stick feel from full pack to empty. NexusFlight is a complete FC + ESC firmware stack with a desktop configurator — built from scratch with algorithms that adapt in flight so you spend less time tuning and more time flying.
Integrated ESC firmware with smoother throttle response than six-step. One-click auto-tune from a blackbox log. 29 FC boards, 220 ESC targets, and a 15-tab configurator that's 10x smaller than Betaflight Configurator.
Currently in hardware integration and flight testing. First flights February 2026. Not recommended for production use yet — beta testers welcome.

NexusFlight Suite — Configurator (v0.4.2), FC Firmware & ESC Firmware (v0.3.2)
Beta Testers Wanted
Hardware integration and flight testing begins this week. We're looking for experienced FPV pilots to test NexusFlight on real hardware. If you have a supported FC board and want to be among the first to fly Rust-based firmware, we want to hear from you.
Source code access available by request. Contact devops@automatanexus.com or submit an access request on GitHub.

4 Components, One Ecosystem
From embedded firmware to desktop tooling — every layer built in Rust
NexusFlight
v0.3.2From-scratch FC firmware — 132,000+ lines of Rust, 551 tests, 29 boards across 5 MCU families (STM32F405/F411/F722/G473/H743) including HDZero boards. Zero heap allocation.
- Adaptive gyro filter — less propwash, less delay, adapts to your style
- Handles wind and dirty air without retuning (ADRC disturbance rejection)
- Cleaner yaw spins — cross-axis decoupling eliminates roll/pitch wobble
- Consistent feel from full battery to empty (gain scheduling)
- One-click auto-tune from a blackbox log (frequency-domain analysis)
- Deterministic 8kHz PID loop — zero jitter, zero surprises
- CRSF/ELRS, SBUS, DShot 150/300/600 (bidirectional), OSD, GPS rescue
- 96-byte blackbox with delta compression for long recording sessions
NexusCoreDrive
v0.3.2From-scratch ESC firmware — 31,000+ lines of Rust, 356 tests, 220 board targets across 4 MCU families. Drop-in replacement for BLHeli/AM32.
- Full sinusoidal FOC + Six-step dual modes
- Q15 fixed-point math — zero floating-point, FOC in <5µs
- Sensorless observer with adaptive LPF
- Autotune: measures R, L, Ke for optimal PI gains
- 5 fault protections (OC, OT, UV, desync, stall)
- EDT telemetry: eRPM, voltage, RMS current, temperature
- 3D mode, DShot commands, AM32 4-way passthrough
NexusGround
v0.4.2Cross-platform desktop configurator built with Tauri v2. Lighter and faster than Electron-based configurators.
- 15 tabs: Setup, Firmware, PID, Rates, Receiver, Motors, Filters, OSD, VTX, GPS, Blackbox, CLI, ESC, Auto-Tune, Debug
- Frequency-domain auto-tune (Bode plot, step response)
- Built-in blackbox log explorer with SVG plots
- ESC/CoreDrive passthrough configuration
- Flash firmware via STM32 UART bootloader (FC & ESC)
- Interactive rates curves & PID tuning
- Cross-platform: Windows & Linux
nexus-core
v0.3.2Pure math flight algorithms library (no_std). Zero hardware dependencies — 401 core tests execute in 40ms on your laptop.
- All 5 flight algorithms — runs and tests on your laptop, no FC needed
- PID + ADRC controllers, Kalman filter, dynamic notch
- Gain scheduling, cross-axis decoupling, airmode mixer
- Betaflight-style rates & expo curves
- AHRS, MSP protocol, OSD, VTX, Blackbox, FFT
- 401 tests execute in 40ms — iterate fast without hardware
What You'll Actually Notice
Less Propwash, Less Delay
Adaptive Kalman gyro filter auto-adjusts to your flying style in real time. No manual filter tuning — it adapts so you don't have to.
Handles Wind & Dirty Air
ADRC disturbance rejection fights wind gusts and prop wash without you touching a PID slider. Fly through dirty air like it's not there.
Cleaner Yaw Spins
Cross-axis decoupling compensates for the roll/pitch wobble that other FCs introduce during fast yaw rotations.
Consistent Feel, Any Battery
Model-based gain scheduling keeps your quad flying the same from a fresh 6S pack to 3.5V per cell. No more mushy end-of-pack handling.
One-Click Tuning
Frequency-domain auto-tune analyzes a blackbox log and calculates optimal PID gains. No guesswork, no test-crash-adjust loops.
Smoother Throttle Response
CoreDrive ESC firmware uses true Field-Oriented Control with sinusoidal commutation. Smoother than BLHeli, more efficient than six-step.
Why NexusFlight?
What changes when your entire flight stack is built from scratch in Rust
| Capability | Traditional Firmware | NexusFlight Suite |
|---|---|---|
| Language | C (manual memory) | Rust (compile-time safety) |
| Memory Safety | Buffer overflows possible | Guaranteed at compile time |
| Heap Allocation | malloc / dynamic | Zero — fully static |
| Gyro Filtering | Static notch / RPM filter | Auto-adapting — less propwash, less delay |
| Wind & Dirty Air | PID only — retune manually | ADRC handles disturbances automatically |
| Yaw Spins | Roll/pitch wobble during yaw | Cross-axis decoupling — clean spins |
| Auto-Tune | Step response only | One-click from a blackbox log |
| ESC Firmware | Separate project (BLHeli/AM32) | Unified stack (CoreDrive) |
| ESC Control | Six-step trapezoidal | True FOC sinusoidal + six-step |
| FOC Pipeline | N/A | <5 µs (Q15 fixed-point) |
| Configurator | Electron (~200 MB) | Tauri v2 (~19 MB) |
| Test Coverage | Minimal | 551 FC tests, 356 ESC tests |
