I'm a builder at heart. The problem for me with ARF's is I can put one together so fast, I am now inundated with airplanes. I'm currently getting a major dose of building therapy with the Ziroli Stuka. Now I can build until my heart is content without worry of where to put another plane. Of course when the stuka is done, I'll have to get rid of 3 ARFs to make room for it.
