One point that is different between CL and RC is that quite often, the controls in CL are not accessible for the occasional look-see like they are for RC. (although who looks!)
Also some will state that the control forces we exert on a CL model for the square maneuvers can be quite high, enough to, over time, beat up even the good clevis.
This has become a religious issue, like the slide-on line clamps or crimping control lines. However there is truth on both sides. I built a Arf Nobler when they first came out, and except for replacing the leadouts and the tank, my Nobler was stock. At the time I wrote a review on SSW, and it was later picked up in Stunt News. In any case, I used the stock clevises and rods. However I put in some of the blue locktite (242, the non-permanent type) on the screw threads, and the system held. In fact when I finally decided to replace the clevis with a ball link the following year, it was quite tough to unnscrew the clevis from the rod. On the other hand I personally witnessed Bill Calkins put in his Arf Nobler at Sig (was it really 2 years ago?) on its second flight. I think the rod pulled out of the clevis on the downward leg of the outside square.
So I am guessing, prudence may be the best! Remember it takes only one failure to eliminate the plane.
