This might not be the correct place for this post (I've no issuues with it being moved), but given the nature of my work it seemed like the best place. I'm having so much fun working on this project that I thot I'd share. I get paid an Engineer's salary to play with engines, how cool is that? APT The OPOC engine design is scaleable. Not sure how much I can say beyond what the page has on it so ask Q's if you've got some and I'll answer what I can. How about some sort of buggy powered by a bigger version of this?
