RE: How many park flyers have YOU seen?
I think that is an EXCELLENT question, I understood it perfectly.
None. Zero. They fly them at my clubs, and they fly them at indoor gatherings, but I do NOT see tons of park flyers at every local soccer field. I do not go to my club field with any worries of being shot down by a park flying unknowingly flying across the way. Most of these totally ready to go ones are on 27mhz anyway.
I'm not afraid of park flyers. They are just fine by me. I don't think kids are really into it, it's not like thirty years ago. Too many other interests.
