MMMv3 ESC package question and some other stuff

[Aceldama]

I've finally grown tired of waiting for the CC/Neu 1800kv motors. And to be honest 1800kv is a bit on the high side for 6s anyway. So I'm thinking the best motor for my 6s truggy is probably the Medusa 36-70-1600 w/heatsink-clamp.

That being said, I'm wondering if the MMMv3 comes with anything?. I'm particularly interested in the CastleLink.

And I guess while I'm at it, does the Medusa come with any connectors installed?

Thanks.
