RE: Is it time to build?
if you really like to build a model from a box of wood that is great. I am not a great fan of ARF's they do not teach you anything about building a plane and the skills to build an airplane,
there are not many kits out there anymore just ARF's, A good kit is the sig astrohog, or the goldberg supersporster, both are easy to build. the astrohog would be the better plane for you since it is a great flyer. then you can move up to the topflight kits you want scale, but those are 6 month projects
