Questions on heat

[Dafni]

Hmm, there seems to be no getting around a fan for me, then.
I have a fan on my brushed ESC, and also have a few fans lying around, those 12V computer fans, 4cm and 8cm, I think.
I'm just hesitant on the Revo bacause I don't really have space and I like the clean look it has now.
But you're right, I'll have a look at this.

80°C on the ESC is the extreme case, after 2 sets of packs back to back.

Wait, just got an idea: How about taking one of those 4mm fans and put it under the shrink wrap? This would look clean as well.
And then I would power it with the 18V from my packs.
Think this would work?? Could I just wire it to the input leads of my controller (which is a warrior 9918, btw)??
