Chassis thoughts... vertical, or horizontal batts

I was wondering the same thing, but with lipo's. Is it ok for the packs to be mounted on their side? I'm in the middle of a conversion on a CRT and setting the lipo's on thier side seems like a good idea. Sorry to hijack, it is kind of on the same topic though.

hijacking, don't be silly, this is a forum.

I have decided im mounting vetical batts (on edge), so there wont be much of anything for a lower chassis deck. This will be pretty light, competitive with the gorrilla maxx chassis. It will be one killer truck.

Also, serum, i made the the center shaft/spur gear holder future proof, in case i ever want to use a center diff. or whatever. The CG will be low also, the motor sits 45mm lower than stock.

BrianG, do you think 2.5mm alum. plate about 6cm wide by 10cm (for Quark, thermal paste) which would be screwed along the 10cm length to the chassis brace. Or do you think some thicker plate alum. and then i machine it to heatsink fins, passive of course. What do you think?

[BrianG]

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?

[BrianG]

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

[zeropointbug]

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?

[BrianG]

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.
