Do You Still Need Low ESR Capacitors in Digital FPV?

Do you still need low ESR capacitors in your FPV builds now that we’ve moved from analog to digital video? Back in the day, a missing cap meant rolling lines, banding, and noise all over your goggles. But with DJI, Walksnail, and HDZero, things have changed. In this video I’ll break down: 🔹 What low ESR capacitors actually do 🔹 Why they were essential for analog VTX 🔹 How they affect modern digital FPV systems 🔹 When you should still add one to your build 🔹 The truth about voltage sag, noise, and reliability Whether you’re building your first quad or fine-tuning a long-range rig, this guide will help you decide if those chunky capacitors still earn their spot on your frame. ☕ Buy me a coffee: https://ko-fi.com/whirlybloke ► Substack - https://whirlybloke.substack.com/ ► Instagram -   / whirlybloke   #whirlybloke 00:00 Intro – Do we still need capacitors in digital FPV? 00:53 Why ESCs and motors create noise 01:20 Analog vs digital – what changes 01:49 What low ESR means and why it matters 02:56 Onboard caps in DJI, Walksnail & HDZero 03:39 Early FPV days & capacitor experiments 04:27 Where to mount capacitors correctly 05:04 Modern 4-in-1 ESCs simplify things 05:22 Sub-5” builds – when you can skip caps 06:02 5” and larger – why caps are essential 06:43 Real flight tests: with vs without a capacitor 07:29 My capacitor recommendations by build size
