Unexplainable cogging

[lincpimp]

Good bullet connectors are as good as direct soldering. However they can get loose and dirty (sounds nasty, huh, lol) where as the direct soldered connection will last without failure (as long as it is done correctly).

I got sick of fixing bullet connectors, so I deleted most of mine. I just recently used some 4mm conectors to test various motors in my xxx-cr. I had purchased a used hacker 12s 540 and tied it out. It cogged and beeped away, I thought that the guy had sold me a dud motor. I was pissed, then I played with the connectors, and cured the problem! I would say that unless you use the 5.5mm connectors or larger, direct soldering is the best bet.
