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.

Yep, I forgot to ask about the bec, use a ccbec if you can.

A fan and good heatsinking is a must, but it is good to test on lower gearing and them gear up until the equipment starts to overheat.

The Quark line of ESC's are not over rated. They will deliver the amperage they advertise.

The catch is the liniar Battery Eliminater Circuit they have built in, isn't capable of carrying the Receiver/Servo's when powered by more than 4S.

The internal BEC just creates soooooooo much heat. Even on 4S, by adding a Castle Creations BEC circuit, ESC temps will be reduced alot.

In other words, if you're NOT using an External BEC, the majority of the heat that you are seeing isn't necessarily coming from the Power FET's inside the speed controller. Most of the heat is coming from the internal BEC that just can't keep up.

The Castle Creations BEC is soo nice also. It gives you the option to adjust the amount of voltage supplied to the Receiver/Servos. I have mine set to 6.0 volts. This makes the Servo's stronger and faster than powering them by an ESC (5.0 volts).

Look in your Quark manual under "Opto-mod" for more information on using an external BEC.

I've been tempted to try one of the large 6 pole Mega Motors in an E maxx.

I wonder how it would do?

Like the 22/50 series? Those look like beasts!

Maybe the 22/45?
