🚁 What to Consider When Sourcing an FPV Flight Controller | F4 vs F7 vs H7 Explained

Choosing the right FPV flight controller can make or break your drone build. In this video, we break down the most important things to consider before you buy — whether you’re building your first FPV quad or upgrading a high-performance racing or freestyle drone.

We cover the key differences between getting a stack vs an all-in-one (AIO) flight controller, and which option is best for your flying style and frame size. You’ll also learn how to choose between F4, F7, and H7 processors, and what each one means for performance, future firmware updates, and peripheral support.

We also dive into practical details like:
✅ UART port count — how many peripherals you can connect (GPS, receivers, VTX, camera control, and more)
✅ Battery cell compatibility — making sure your flight controller supports your LiPo or Li-Ion setup
✅ Expandability and wiring options — planning for future upgrades
✅ Build type considerations — racing, freestyle, cinematic, or long-range FPV

Whether you’re running Betaflight, iNav, or building a custom FPV setup, this guide will help you choose the right hardware with confidence.
