i do rc, here's why, i run 8 frame medium supers, the capped comb is very thick. i can cut this quicker and with greater ease using a plane rather than a heated knife, and the plane's depth is adjustable. what i do is i adjust the depth of the plane to only cut even with the frame itself and nothing deeper than that, the more you cut off, the more work the bees have to re-draw the comb out. the other reason i like them is because the element is replaceable, whereas when a hot knife dies, you buy another. the only thing about this is you are not going to be wanting to replace the element in the middle of uncapping frames or extracting.......
i keep a back up, or one could even keep a hot knife or serrated knife as a back up on hand.
with that said, it will take a great deal of uncapping frames to burn that element out. i have only replaced mine once in 10 years. it died as i was just starting to uncap frames from about 28 supers one year.......
