Has a worthy ESC been born? The Castle XLX2 looks to be an excellent ESC.

[RaceMechaniX]

Woo-hoo. Getting close. Just curious...for the water line fittings, why plastic, instead of metal?

Trying to keep the costs down and not burden Gabe at Stumpfab with too many options. In the instructions I will offer links to metal fittings since the price and size vary considerably. Likewise I will make recommendations on thermal grease and thermal epoxy. You can choose your level of performance.

Fantastic...and, I'm sure I'm not the only one thinking this, but "thank you" for that info. Looking forward to getting an order in (as long as they don't sell out before I can order).

The parts look great. Will Stump be making coolers for the Mamba X8s as well or is that Don's baby?

[RaceMechaniX]

If someone is willing to send me a X8S to pull or send me the dimensions of the cooling pad I can design a set and ask Gabe if he is interested in this size as well.
I think we will want to see how well the first batch sells for the XLX2 before adding the X8S controller.

Guys, the coolers are available now on Stump Fabs online store. $40 is a steal combined with a $250 ESC get's you the best performing ESC we have seen in a decade.

On order. Woohoo. Still waiting for ESC to arrive.

Thanks Tyler.

Great work you guys!

Order in.

Tyler, I have one quick question. Between the thermal adhesive tape, Zinc-Oxide Thermal glue, and Silver bearing 2-part epoxy, which would be your top recommendation? All three are probably "worthy enough"...but, just 'curious' (as I'm sure others might be) what your 'order of preference' would be for these three.

Tyler, what do u recommend to use for the thermo bonding of the cool plate? Brand/where to purchase. Thanks.

The silver bearing 2-part epoxy is my favorite, but it's extremely expensive. It sells for $142 for a 0.5oz combo. The best value is using a heat sink grease for computer CPU's. Something like Artic Silver MX-4. These have decently high thermal conductivity ratings and are available in very small sizes. So long as you don't mind using zip ties to hold the heat sink secure then this is best value solution.

[RaceMechaniX]

Hey guys,

We have gotten some feedback that zip ties or tape is not cosmetically ideal for some customers. Gabe and I discussed today we will work on a 3D printed cover that secures the cooling plate in place. I also have a Mamba Monster X8S on order so we will get working on that one too.

Although I do have Artic Silver (I build computers for people "on the side"), I tend to only use it when building a computer having a fan-cooled CPU, or a liquid cooled system where the pump is its own separate unit. When it comes to building computers, I avoid electrically-conductive like the plague...especially when building a liquid-cooled system (many of which have the pump install the water block), as the last thing anyone would want is a a power-spike from the pump passing through, and "electrocuting" the CPU.

Plus, I'd prefer something with more "holding power". That's the primary reason why I mentioned the three I mentioned. Unfortunately, it sounds like that particular epoxy is a bit...a BIG bit...on the pricy side. I'm assuming any quality thermally-conductive, but not electrically-conductive, epoxy would work, correct? Or, is it safe to use an electrically-conductive epoxy? Since this is the first time I will be doing this, I am unaware as to whether, or not, there is any potential for...say...electricity to pass through the water, and damage the motor. That is why I was thinking a non-electrically conductive epoxy might be a better choice.

[RaceMechaniX]

You can use electrically conductive epoxy or grease so long as it does not ooze out near the battery or motor connections. If you can find a high quality thin thermal pad this will also work. I just don't have much experience with these outside of light duty applications.

We'll work on the 3D printed pressure cage which will allow the non-setting type compounds a method to secure the chiller and keep pressure on the chill plate.

[fweasel]

I thought the cooler was screwed down. What are the four caphead screws for? Is the cooler two pieces?

[longballlumber]

Yes, it's a stand alone 2 piece unit that will then need to be secured mechanically or epoxied to the controller.
