Flywoo Capacitor Kit

Capacitors act as a buffer for your drone's power system. They smooth out voltage spikes caused by your motors and ESCs, which protects your sensitive flight controller and video transmitter from electrical noise and potential damage.

A good rule of thumb is to choose a capacitor with a voltage rating at least 1.5 to 2 times higher than your battery voltage. For example, use a 35V or 50V capacitor for a 4S (16.8V) battery setup to ensure it handles spikes safely.

Yes, higher capacitance generally provides better filtering, but it also adds slightly more weight and bulk. For most 5-inch freestyle or racing builds, 470uF is a standard, reliable choice, while 220uF is often sufficient for smaller, lighter builds.

Yes, these are polarized electrolytic capacitors. You must solder the negative lead (marked with a stripe on the side of the capacitor) to the ground pad and the positive lead to the positive voltage pad; reversing them can cause the capacitor to fail or pop.

These are universal components. While branded by Flywoo, they are compatible with any FPV drone or RC aircraft that requires through-hole mounting for power filtering.
