Rich,
I'll second John's comments here. CA hinges have their benefits: cheap and easy to install, light, etc. However, they require extra force to deflect, and that force grows with the deflection angle. Also, they (like most plastics) gets stiffer with lower temperatures, so on a cool morning they will feel stiffer than on a 90-degree day. The RC guys can't run into the Netzeband wall: their control force comes from servos, which simply draw a little more current if extra force is required. The guy at the transmitter doesn't feel any "side effects". With control line, we worry about running out of available line tension (mostly overhead) before we can deflect those flaps and elevators.
Here's where I think CA hinges can be used in CL: simple 0.20-.40 size trainers with elevator only. To reduce the bending force necessary, I usually cut the standard 1/2" wide strips in half, and install about 4-5 of the resulting 1/4" hinges; the total force required is like bending 1" strip of plastic. Kids usually crash trainers long before any hinge will wear out.
For larger planes (say, SV-11 ARF), do the math: we have typically 12 hinges, at 1" wide each. It's like bending a 12" long strip of plastic, that constantly wants to return itself into the neutral position. I'm building the SV-11 right now, and will be replacing those with pinned hinges. Interestingly, the building manual shows pinned hinges and better quality horns than those supplied with the kit. But I can't complain, it's still a lot of plane for the money.
