SpeedyBee F405 V5 Stack Pro Kit (55A)

Let's be honest, nobody enjoys crouching over a laptop in a damp UK field, praying to the Betaflight gods while your mates are ripping packs. The SpeedyBee F405 V5 Stack Pro Kit is your official release from that digital purgatory. This isn't just another 55A 30x30 flight stack; it's a complete builder's care package. With its workhorse F405 FC, a beefy 55A OX32 ESC, and glorious wireless tuning, you can flash firmware and tweak PIDs entirely from your phone. Welcome to the future.

Why You Want It

Because your time is worth more than the tangled mess of USB cables at the bottom of your flight bag. This Pro bundle is for the pilot who's released the magic smoke one too many times. On top of the legendary SpeedyBee wireless convenience, you get the tools to build it right first time: a soldering practice board to warm up your shaky hands and a smart short-circuit protector to save your new £70 investment from a momentary lapse in judgement. We're basically selling you peace of mind, with a flight stack attached.

The 'Pro' Part: What Makes This a Deluxe FPV Flight Stack?

It's the stuff that separates a clean build from a fire hazard. SpeedyBee bundled in the essentials that experienced builders already have, and that new pilots desperately need. Think of it as your build-day safety net.

• Soldering Practice Board: Get your eye in before you touch the flight controller. Cheaper to burn this than your ESC.
• Power Expansion Board: Tidy up your BEC and power wiring like a pro. No more rat's nests.
• USB Extension Board: Mount your USB-C port somewhere sensible, not buried under your GoPro mount.
• Smart Short Circuit Protector: The real MVP. Plugs in before your LiPo and tells you if you've made a terrible mistake, without the fireworks.

• Bluetooth Tuning: Yes, the main reason you're here. Full control via the SpeedyBee App.
• Blackbox: 16MB Onboard (Because you need irrefutable proof you hit that gap)
• BEC 5V Output: 9 groups, 1.5A total. Power more LEDs than a Vegas slot machine.
• BEC 9V Output: 2 groups, 3A total. For your power-hungry DJI O3 or Walksnail VTX.
