With a dieselized 074 you will need steel lines, either 008 or 012, 40 to 50 ft long (don't really have a good figure for you). If you have not flown CL before, I'd suggest a simple all sheet trainer with things rubber banded together for crash survivability. Also set up for short flights at first, 10 laps or so, so that you don't get too dizzy.

I see you have done some CL before; even so, a fairly cheap and simple airplane to get reoriented and get over the dizzies is not a bad idea.
