how much percentages/royalties to i ask for?

i would like to know how much of a percentage i should charge for designing a complete line of toys for toy company that’s just starting? any idea on royalties, if i should ask for a stake in the company…

Thanks in advance. I’m pretty clueless about this aspect. I know what to charge for freelance and such, but royalties and cuts, I think I’ll need a bit of advice from you experienced folks.

Best,

H

oops. nevermind. just saw a recent similar post. but any additonal feedback/insights would be great anyway.
