Enough said.

I used some of those rings when I getting bad glitching on my crt.5 (4s a123, feigao 9l, mamba max, futaba 2.4ghz). I could even notice it with just the power system sitting on my bench. Ferrite rings made things worse for some reason, heeeaaaps worse. electronics positioning was not the problem (I even isolated the high power stuff completely on my bench when i was testing).

Still never figured out the problem *shrugs* I thought it was the MM and sent it back and they said there was nothing wrong with it. Not the case, I just don't run it anymore. Pity, really. Just waiting till i cbf posting it up here for sale heh.
