Hi kaos2,
I was in your situation a few years back and went with a ARF trainer and instructor for a few flights whilst I was building a kit. Once I had my confidence back it seemed like I had never stopped flying and was quickly back to the old skill levels (or lack of skill?

).
Maybe it is because there was a twenty odd year break but I am now much more relaxed flying than I was in my twenties and thirties. Maybe its' the Prozac???
Good Luck and Welcome back,
Colin
