Seriously? :shock: I wish I could say the same. Mine, of course, got much smoother after the software update, but the cogging did not completely disappear. I also have the drag brake cogging that I haven't figured out yet. Do you mind sharing your MMX settings?There's a part of me that misses my Holmes 540XL 3500kv. It's just brutal power that makes you giggle with every trigger pull. I wish I could try one out on the new MMX firmware to see for myself. I ran it on the same MMX when I had one and smooth was not the word I would use to describe it. I have no doubts the new firmware improved low speed control though. It made my Holmes non XLs feel even better than I thought was possible for brushless. Very interested to hear your thoughts, FFWF.
