I understand your point.
The point of view I am coming from is that most of my flying
is done with my brother and/or my best friend.
They both have small children that come with us flying
sometimes. My daughter is grown and moved out but
my parental instincts are still there and pointed towards
reasonable risk minimization.
I feel in my case there could be an exposure risk to carbon
dust and fragments to the children should I crash (When Don't
I crash ... heh
I can build good planes of the type I like to fly without carbon
fiber. Specialy with the help of the fine group of people on the rcgroups board.
Keep em flying
