Let me as a newbie (well to air planes anyways) key in. I bought my trainer as a arf why?, well I did not feel that I wanted to spend the time to build a plane that I was going to out grow. Now I want to build a kit why?, because thats the 1/2 the fun of it. Why do we build model cars when we can buy diecast cars? Because the building is the fun part. Just my .02.
