Hi Sporty, Welcome to the forum. I'm not Ruben, but I also can answer your question. Just keep looking around and enjoy the builds and threads here. Keep posting for a while longer. After about 8 or 10 posts (if I recall correctly) you will get a better access to the forum itself. The DC3 is available in the download section here. It is a very large file containing several liveries and there also are a couple of additional separately available files for improvement here and there.
Have a nice time here and please also share your builds with us! And please visit our forum's
Welcome desk, too, to introduce yourself 'officially'.
