Downtrodden, I've been fooling with one kind of an engine or another since I was a kid. That is one part of this hobby I feel comfortable with. As far as building, when I try to glue two popsicle sticks together, I break the sticks and glue them to my hands. I sure wish I knew how to build. I think I started the hobby too late to learn. ARF's (and a friend who loves to build) are probably what has kept me in this hobby.
