If i do find a field, should I get a RTF or a kit? Would a kit be a bad thing, since Ive never had experience with a plane like these? How long do first builds usually take?

Im thinking either a [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXEXK2**&P=0]NexSTAR[/link] RTF or a [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJ557&P=0]Great Planes PT-40 MKII Trainer Kit .35-.46,60"[/link] Kit.

I would love to build a kit, but im not sure if its worth doing. I mean if I do go to a field I would hope to have a plane by summer when im out of school, but I doubt I could build a kit on the weekends and spare time.
