INAV and Betaflight are the two most popular open-source flight controller firmware projects. While they share common roots in the MultiWii/Cleanflight heritage, they've evolved to serve different purposes. This guide breaks down every difference to help you make the right choice.
Quick Summary
| Feature | INAV | Betaflight |
|---|---|---|
| Primary Focus | GPS Navigation & Autonomous Flight | Acrobatic FPV Racing |
| Fixed-Wing Support | ✅ Full support | ⚠️ Limited |
| GPS Navigation | ✅ Waypoints, RTH, Position Hold | ⚠️ GPS Rescue only |
| VTOL Support | ✅ Full VTOL | ❌ No |
| Acro/Freestyle | ⚠️ Good but not primary | ✅ Best-in-class |
| OSD | ✅ Rich navigation OSD | ✅ Rich flight OSD |
| Waypoint Missions | ✅ Full mission planning | ❌ No |
| Return-to-Home | ✅ Advanced RTH with altitude control | ⚠️ Basic GPS Rescue |
| Supported Boards | Wide range | Wider range |
When to Choose INAV
- Long-range FPV — INAV's GPS navigation, RTH, and failsafe are essential for beyond-visual-line-of-sight flights
- Fixed-wing aircraft — INAV has first-class fixed-wing support with autolaunch, autoland, cruise control
- Autonomous missions — Waypoint missions, geofencing, safehomes
- VTOL builds — Transition between multirotor and fixed-wing flight
- Aerial photography/mapping — Stable position hold and autonomous flight paths
When to Choose Betaflight
- FPV racing — Betaflight's PID controller is optimized for aggressive flying
- Freestyle tricks — Better acro feel and fine-tuned motor control
- Tiny whoops — Better support for micro quads
- Short-range proximity flying — No GPS needed
GPS Navigation — The Biggest Difference
INAV was built from the ground up for GPS-assisted flight. It supports:
- Return-to-Home (RTH) with configurable altitude, speed, and landing behavior
- Position Hold (POSHOLD) — hover in place using GPS
- Waypoint Missions — plan autonomous flight paths with altitude, speed, and actions at each waypoint
- Cruise Control — maintain heading and altitude for fixed-wing aircraft
- Safehomes — alternative landing locations when home position is not reachable
- Geozones — virtual boundaries to prevent flyaways
Betaflight only offers GPS Rescue, which is a basic emergency return feature. It cannot plan missions, hold position precisely, or navigate autonomously.
Supported Hardware
Both firmware support STM32F4, F7, and H7 flight controllers. INAV additionally supports AT32 processors. Popular boards for INAV include:
- Matek F405-Wing, F765-Wing — purpose-built for fixed-wing
- SpeedyBee F405 V4 — popular all-around FC
- Matek H743-Wing — high-end fixed-wing controller
- JHEMCU GF30F722 — compact multirotor FC
- Flywoo GOKU GN745 — versatile board
Conclusion
If you need GPS navigation, autonomous flight, or fixed-wing support, INAV is the clear winner. If you want the best acrobatic FPV experience, Betaflight remains king. Many pilots run both — Betaflight on their racing quads and INAV on their long-range and fixed-wing builds.
