Everything CB said is correct. Get with the club you mentioned. I would get an ARF trainer just so you can be flying while we have good weather. The two trainers I would recommend are the Tower trainer and the Hobbico Superstar. Mainly because both are covered with monokote which will make repairs easier than the trainers covered with the shelf paper covering.

And yes start building a plane. I personally love to build. just as much if not more than flying. When I started flying in 1978 you built your own plane or you didn't fly unless you bought a used plane. I have 3 kits stashed away now and am thinking about buying a couple more just to have them. I prefer glow power over electric and recommend that whatever you build it will be able to use the power plant of your trainer after you become bored with it or kill it. But then again having a trainer for relaxing flying isn't a bad idea either.

Happy hunting and welcome back to the hobby.
