I attached the Quark naked board to a decent sized heatsink with the stock thermal sticky pads, and then shrink wrapped it, as well as adding two extra caps on the input bar, opposite of the stock caps. (this is temporary)
Even with a large heasink on there, and moderate driving the Quark got very hot. The heatsink got very hot and just almost as hot as the output wires, but no thermals, and the caps stayed only slightly warm to touch.

AAngel: With my Spektrum radio now, I don't have the low speed capability I had with the stock TQ-3 radio, it's definitely not a snails crawl anymore, which I miss... but no more glitching! |
Looks good ZPB. How hot is hot? Did you temp it?
One thing though, it looks like the shrink is all the way around the heatsink. You might want to allow some better air flow over the heat sink fins so it can get rid of the heat.
