Still, within that hemisphere you can do things that stress models way beyond what RC usually encounters...like fly combat at 110 mph - 60 feet from you, fly a precision pattern while trying for the elusive five foot radius corner in a square maneuver, etc.
Each has its good and better (no bad) parts.
CL is not going away. As a matter of fact it's still growing. The numbers are small compared to RC, and some of us fly both.
Since many hobby shops will not carry CL stuff, we rely mostly on cottage industries and mail order. Sig still has CL equipment, and Brodak's has CL exclusively. Even Tower offers some CL equipment including a couple of CL ARF's and some CL engines.
If you can't find CL stuff locally, I would suggest getting a Sig and Brodak catalog.
