Everyone who said "Sig Kit" is right. Great kits, good quality instructions. (I do not have experience with Carolina Customs, so I can't provide input. Sig is nice because their instructions not only tell you how to build the specific airplane, they also provide building tips for rookies.)

Are you ready to build? Spend considerable time in the basement, get CA all over your fingers, sand, sand, and sand some more? If yes, then go with Sig.

If no, well, maybe ARF - and if you go that route my suggestion is go foamie for a trainer. (I'm a balsa guy, but fully respect and appreciate the simplicity and ruggedness of foamies.)

My 2 cents.
