Chassis thoughts... vertical, or horizontal batts - RC-Monster Forums

Generally, the thicker the plate for a heatsink the better (to a point). You need thermal mass to pull the heat away, then fins to dissipate it. I would use 1/8" thick aluminum, but maybe not so long/wide. Using the chassis as a secondary heatsink is always a good idea, but I don't like to count on it.

Well then maybe i'll use the same 6mm stuff the braces are made from and machine fines into it (3mm) and the other 3mm for heat spreader. This should keep the thing as chilly as a male penguin waiting for his love to return. :005:

Also, im curious, do you have pics of your E Revo by any chance?

Yeah, I have some pics: Pic1, Pic2. The colors are washed out because the camera I used at the time was kinda crappy.

That's one nice setup man. But hey i thought you said you had your Quark's heatsink on the bottom of it?

Also, im just trying to remember who was it that did the Quark mod, you and who else?

Thanks!

I do have the heatsink on the bottom. The heatsink is a 1/8" thick piece of angle aluminum with extra heatsinks epoxied on top. This allowed me to mount it the ESC on its side to save some room. The pic below is a little different than it is now (the top HS are different and larger), but you get the idea...

Smertzhog (I hope I spelled that right) did a mod where he attached super large heatsinks all over it. Jhautz machined the heatsink found here in the store. Maybe one or two others have done some type of mod, but I can't remember off hand.

Wow, cool, it only makes sense making the heatsink come the sides of the esc. I can't however, as much as i would like to, oh well, im sure it will never thermal, as hard as i would push the system. Not that i would push it that hard anyways, but like you said, it's just a good feeling knowing nothing will ever happen. Plus i bought the 540C 7xl, so the motor HS should add more peace of mind too. My truck will weight 9 lbs now, and 7.5 lbs with 1/8 tires on it. :017:
