I have been building for about twenty yaers now, and have nerver once considered an ARF. Even if my time is limited, and soimetimes it is(very). The fact that someone else has assembled some thing that not only FLYS.. but has the potential to do great damage/ harm really bothers me. I trust my judgment, through years of experience, and input from fellow modelers at our club with many years modeling. Just reading some of the responses in this thread only reinforces my feelings. ALSO i love the fact that MY plane internally and FINISH as well is my own, i almost never use the kit manufacturers scheme, and almost always modify the intenal hookups to my liking, (seems like MOST builders do this to suit what they like). LAST but not least is the GREAT satifaction i get when my two hands Create what i consider to be mans greatest contributiontions, a flying machine. I have started building a Trainor with my son and hope he can enjoy the process of Building with his kids as well.
