Quark on 6S with Mega 6 pole

[sikeston34m]

I have heard no mention of a BEC being used.

Are you using a BEC with this? Because if you're not, it's going to fry the internal bec very quickly.

The Quark 125 amp version is capable of alot. I've ran 6S on 2 of mine without any issues using multi-pole motors.

As far as heat issues go, you're alot better off to mount it to an aluminum surface, if you have one available. Coat the underside with thermal heat sink compound, then secure it with ties or something.

A fan doesn't hurt anything either, especially if you're going into that upper realm of it's ratings.

I hope this helps.
