thanks joser and welcome to the forum. lots of building going on here and more to come.
re arf's, i find i go through stages, sometimes lots of building, then something arf takes my fancy, then enough of that, back to the building.
i think arf has its place, especially if you want to get into flying quickly. i'm sure lots of guys who would never have got into models did so because arf's were so readily available. once you're comfortable flying with a couple of models under your belt, then it's time to consider building your own. with a bit of practice on easy-build models who's to say what you might take on as a project, even a ka-3!! (me climbing down off speech box).
are you going to show us some of your work joser? please do, we'd love to see it.
