I usually just use a 1,000uF rated ~10v. If you are using a heavy duty servo, you could go up to 4,700uF, but the cap will be physically bigger.

Most of the noise will probably be at whatever the BEC switches at (I've seen anywhere from 20kHz to 250kHz) and will be most evident at higher loads. And since this BEC also supplies DC power to potentially sensitive receiver circuits, I take no chances. :)
