no copyright infringement if you sell the original plans... if you make copies that's another issue, the quesion is how much does it matter? you can blow up the plans that came on RCM, than make some technical changes to it and it can be called your own.

OHhhhh the Society:boxing:... Older guys correct me if I'm wrong...in the (g)olden days it was kind of an honor if somebody else used your design and your heart felt warmer... Nowadays everybody worries about copyrights and lawyers and such and how much $$$ can get out of something... so the wallet feels warmer and the heart shrinks... like the Grinch pirate:
