New heatsink idea. - RC-Monster Forums

How does that work SMHERTZOG? We were thinking of something a little more civilized? :005:

I think I might have said this before, but the heatsinks on the caps won't do anything for cooling, almost no contact area.

I will post a pic of what I had in mind, for a Quark case (CAD Design). This might take me a couple days to work out. :030:

Also, that heatsink will not perform as well as RC-Monster's, IMO.

Crap, I don't have any dimensions right now (Quark sent for replacement), so I can't make an accurate design.

yeah, pin milling is expensive and hard to do. But there is alot of surface area, like THIS, I don't know how they make those?:032:

The caps get at least 30-40 degrees more than the hottest place on the heat sink. The caps get so hot that the heat shrink peeled off. Maybe the extra caps quark has mentioned will help keep the cap temps down. It may be ugly but it works. How many quarks have you seen running a 10+lb gmaxx in 90f heat with a 7xl, orion lipos, and geared for 40+ mph without thermaling and all with no fan?

I have a 7XL too, I did the internal mod to it, but I don't know if it was just my radio TQ-3 (i know, i know) but after about 10+mins, it would sometimes stop. I wonder if it was a thermal, because it stopped, and I went and pushed it with my foot, the brakes are on?

Also, I was talking about the other heatsink there, not yours SMHERTZOG, just in case... :032:

Yes, I would recommend soldering some caps to your Quark, that will help save those caps, the 7XL is one current greedy motha.

I had similar problem with my first quark. Although I was using a spektrum radio at the time. It would just stop I dont remeber if the brakes were on. I would wiggle the throttle and it would start up again. That one took a dump and the replacement didnt do it.
