HappyModel X14 ELRS Flight Controller

Let's be honest, the guts of your 2S whoop have seen better days. Enter the HappyModel X14 ELRS Flight Controller, the AIO board that finally crams a proper brain into a tiny package. This isn't just another F4 board with a new sticker; it's a full STM32G473 upgrade with an integrated 400mW OpenVTX and a buttery-smooth 12A Bluejay ESC. If you're building the ultimate 75-85mm toothpick or just reviving a sad, underpowered Mobula, this 2S whoop AIO is the only sensible choice.

Why You Want It

Because your current flight controller has the processing power of a potato and you're tired of watching your video feed turn to static just by looking at a tree. This all-in-one board consolidates your receiver, ESC, and a shockingly powerful VTX, saving you weight, solder pads, and sanity. It's the simplest way to give your micro-drone an IQ boost and a signal that actually punches through walls, all without having to sell a kidney. (We checked, they're not legal tender in the UK anyway).

Specifications

• MCU: STM32G473CEU6 (More processing power than your first laptop)

Still Here?

Seriously, you read the whole thing? We're impressed. You're either a spec-obsessed pro or you're really, *really* procrastinating. You've now absorbed enough information to perform a Mobula8 flight controller upgrade in your sleep. Since you're clearly one of us, do your mates a favour and share this page so they can stop complaining about their rubbish range. Or just buy the thing already; it won't get cheaper by staring at it.
