This thing is nothing but a capacitor - but - in the hobby trade they're called glitch busters. Why? Because under load some receivers will reset (brownout) leading the servo to glitch when it comes back alive. So the way the capacitor works is it gooses the receiver with enough current to keep this from happening, hence the moniker . . . glitch buster! They're also useful to goose the servo losing too much voltage due to being on a long extension. We recommend adding capacitance at the load end when the extension exceeds 30 inches.
