RC-Monster Forums - View Single Post - Quark 125B works, but stops after 3 minutes...

ncalenda · 11:22 PM

I installed the Quark in my e-maxx today, to only find it would do 2 laps on the track before it would thermal, I was running 5S, so I tried 4S and I got another lap extra, I was not happy.

Now, I do have the heat sink from rc-monster. I have a few questions to see if I can fix this problem:

1. Do I use the heat sink on the top or bottom? I have it on the bottom (with the ESC on its side), so I could have access to the program button.

2. Should I lay it flat on my FLM chassis? With the button side down, and the heat sink on the bottom face up? What is the best way to install it so that it will run cooler?

3. I set Li-Poly High, and I'm running MaxAmps 5S 8000. Should I try Li-Poly Normal?

4. Should I cut out holes in the body? I haven't done this yet, to keep it clean inside. But, with it the way it is now, I can't even run it for 3 minutes with it stopping.

More info:
Around 9lbs with no batteries
Castles BEC
3 fans, 1 for motor and 2 for ESC, using rc-monsters heat sink
I wire the fans directly to the batteries
9xl
Strobe Spur 51/14

Any other ideas, is greatly appreciated!!
