Trainer Size .60 or .40
I was the same way, I left the hobby. Was doing pretty good before I had to quit. I re-entered the hobby with a duraplane 40 with the idea of less money to re-build or loose if and when I crashed. What I was amazed at was how much I remembered when I got back into the sport. I wish I would have went witha different plane. I've out grew all the diheidral so fast it's kinda discourged me, but I'm quickly building a Tiger 60 on which I'm going to put a Saito 91. If I was you, and had soloed before I left the hobby I would go with a Avistar. Great flying planes, and are capable of what most of your flat bottom winged trainers aren't.
