New heatsink idea.

[QUOTE=zeropointbug]I have a XL 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?QUOTE]

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.
