90%! My arse! These ARF's are build in China and Korea by guys that could care less whether it crashes. A person who builds a plane invests the time to make it right. Anyone can believe their ARF, (ARF is an acronym for puking) is better than my home built plane but I'll put my planes (one right now) (4th plane total) up against anyones ARF any time! The same people that build sunbeam stuff at Walmart put those ARF's together.
