Quark 125b thermaling

[smhertzog]

I am having problemes with my quark thermaling after about 10 minutes of running. I had two of the large novak fans on it and am running 20/66 gears with 1/8th scale buggy diffs. I switched back to my old MGM controller with no fan and had no problemes. I talked to Frank on Radio Control Zone forum, he's a rep for Quark. He said with my setup I will be able to run 6-7 minutes before it thermals? He said brushless technology is new and this is all I can get from their controller or any controller for that matter? I also tried gearing down like frank told me too and it helped but then my truck was lucky if it went 30 mph. I then took it up a gear and it started thermaling again? If you would like to see the posts by the Quark rep here it is: http://forums.radiocontrolzone.com/s...st2033099:031: I was hoping I got a bad controller but after reading this post I dont know what to do.
