In regards to the Revell/Foose partnership I don't think it is out of line to believe he would invest some capital in the project. That would also help justify doing one off customs that can't be modified easily for more versions to help pay for the tooling. And yes, of course they are going to pay him royalties. I could also see him getting a bigger portion of the profits/royalties from the following kits in this line to repay the initial capital invested on his part. As they say it takes money to make money.
