RE: Why is CL losing popularity?
I read a comment somewhere in an RC article some years ago to the effect that one day all modeling would be reduced to electric CL because of space, noise, etc. etc. Hopefully that is far in the future.
The fact is that competition stunt and sport flying are much healthier than they were 20 years ago (at least in my experience). Other aspects of CL are not doing so well, but still hanging in there. It will be interesting to see what the increasing numbers of quality ARFs will do for CL. I'm really waiting to see who will put a fully stunt-pattern capable electric on the CL market.
