>>82112009They probably both get the standard tiny salary that Coco and others mentioned, but it's not really worth considering because it's very small compared to the money they all make from other sources of revenue.
Usually, as far as channel earnings go, the revenue is split evenly between Cover and the talent after Google takes its 30% cut. Since there's only one youtube channel, it's unlikely that they're getting twice the revenue split as other members because that would mean Cover would get nothing. It might be possible that they and Cover split their channel earnings three ways instead of two after the Google cut, but they've never said anything about that and I doubt they ever will. It's probably safer to assume that the channel's revenue split is 30%/17.5%/17.5%/35% between Google, Fuwawa, Mococo, and Cover respectively. However, Fuwawa and Mococo almost assuredly share bank accounts and so it doesn't really matter what their individual split is.
