Why would you worry about enjoying building more than flying? I think Sandman had a couple of great points and suggestions.
When I first started in R/C some 15 years ago, I 'took the plunge' with a GP PT-40 ARF. There was a lot to learn about engines, electronics etc. But when I took it out the first time with an instructor I was simply thrilled that it got off the ground. Anticipating that R/C planes have a limited (and uncertain) lifespan, I bought a PT-40 kit. That kit taught me an awful lot and, although I did solo on the ARF, when the inevitable pilot error struck, the kit was just about ready to go. Took all the components from the ARF, got them installed and took up the kit. It flew so much better I couldn't believe it. That led to a .40 size GP Cub and from there it's history. I've built several nice TopFlite warbirds, Sig Astro-hogs and bipes, some BUSA kits (just finished their D-VIII), several Flair kits and a few birds from plans. I'm a decent pilot but no 3-D. Doesn't interest me. But if you find you enjoy building you'll really enjoy bringing out a new, unique bird every few months because there aren't too many out there these days. Yes, I still slap together an ARF once in a while because I WANT to. The H-9 Hellcat is one of my favorites and I fly her with a little more abandon than say my Flair Puppeteer. But so what?

A fellow at the field once asked me how much time I spent building vs. flying. I think I told him about 80% of my time was building. In re-thinking that, it's more like 90+%. Six months of shop time for maybe 100 eight or 10 minute flites on an airframe? Just might be! The answer, at least for me, is to do both kits/plans built and an ARF now and then. Even though I get out to the field maybe 100 days per year there are a LOT of hours in those other 265 days . Sometimes, I might just put in 20 minutes in an evening. But there is a sense of accomplishment, progress- even if it's slow. I've passed the point in my life where life is a 'race'.

Whatever you decide, enjoy it! About 3 years ago, I took my old GP Cub which has been on floats for 8 years and spent about 2 months building a Midwest canoe kit for it. Building that canoe was a blast and strapping it onto the struts of the Cub really adds to the realism. In fact our club does a display once a year at a museum called Wings Over the Rockies and when I ask the guys if I should bring the Eindecker or the AT-6 (I'm proud of both) they all say 'Bring out the Cub with the canoe!'. Go figure. And as the folks pass by during the day I hear 'Hey Dad, look at that canoe'. Makes me smile.

Best of luck!
