I understand that this thread is years old but I thought the answer would be clearer than this. I had 2 Darts and 1 of the Royal trainers in the 80s-90s era. But I really think the ARF that really transformed, or truly started the ARF era was Hangar 9 Matt Chapman Cap. I think the ARF craze jumped to a new level with that plane and I am astounded that it has not been mentioned earlier. (or has it and I just missed it?)
