I prefer to build, when I started in the mid 80's, all ARF's were pretty much Junk. I learned to build from the get go, BUT I have built and flown the snot out of several ARF's over the last 5 years. Sure they needed some going over, but all flew and held up very well. I love to build, but I will always have an ARF or two in my hangar.
Either way it boils down to the individual "having FUN", ARF or Build.
