A couple of questions

[Marvin]

Hi all
Set up:
Batteries : 2 4900mAh Trakpower in series (so 4s)
ESC: MMM
Motor: 2650kV CC Neu
My 1st question is:
Would 4mm Gold Tubes (Corally connectors) be good enough to run on a brushless conv in a truggy? Would they handle the current?
My 2nd question is:
Does the MMM have a switch, or is it just plug in the batteries and it comes on? It would be good if it did have a switch as I'm not running the BEC.
My 3rd question is:
What voltage do cooling fans generally run on (e.g. the MMM's cooling fan) as I'm planning on having a few of these...

Thanks guys, I'm sure your advice will be ace as normal...
