That is true, the legs don't glow at all with tightly wound coils (but of course they do get hot). I have ben running tightly wound micro & mini coils in all my RBAs & on none of them do the legs glow. But on my RSST the coil in it now is not tightly coiled & one leg does glow. I've been meaning to make a new coil for it but I don't use it all that much.
