I'm getting back into the hobby after a short (~5 years?) semi-absence.

I ordered the plans for a Loaded Dice II, Gitano 60, and a Vector II. The first 2 use 60's, the latter a 40 size engine.
During research on these models, I also found out about the LDIII, and am wondering if this plane is pretty much just for the 1.2-1.x engines with tuned pipes, or if it could be used with "regular" 2 or 4 stroke engines w/o a pipe. I'm not looking for F3A performance, so I don't really need hot performance. If were to get into pattern again, it'd be more like sportsman level.
