BrianG,

I hear what you are saying; but on the other hand, I wonder if going with the 13 gauge wire was settled on taking certain factors into consideration.

From a manufacturing cost standpoint, I think that it's reasonable to assume that 13 gauge wire costs less than 12 gauge wire. If I were manufacturing the MM controllers and 13 gauge was more than good enough for the esc's intended purpose, then I can see why they would go with the thinner wire. We are, of course, running the MMs "out of spec." I may just happen to be that the 12 gauge wire is better suited to our applications. I don't think that the 13 gauge wire is any indication of "being on the hairy edge." My MMs run cool in my conversions and now, I don't have the problem of the wires heating up; not to mention that I'm having less cogging than I did with the thinner wire.

I do have to comment about doing the actual wire swap. I'll acknowledge that I'm not a soldering genius by any stretch of the imagination, but I do well enough. I'm also not using some radio shack stick iron. I use a Metcal MX500, which I believe to be among the best soldering stations that you can get. I'm also using a 700 degree broad chisel tip to do the soldering; and it isn't just a matter of touching the iron to the solder joints to break them loose. The whole esc acts as a heat sink and getting the joints up to melting temp can be kind of hard. All I'm saying is that I'd recommend a good soldering iron if you're gonna do the wire swap.
