Well after work tonight I just ran 2 full charges through it using 8000mah 5s setup and Feigao 9XL. Gearing started at 22/70. It was just about exactly 80 air temps outside. Before I plugged anything up and started running I took a baseline reading on the motor and the Quark. Both right about 84.
Started off running easy, then ripped into it after I saw the temps were so low. Didn't matter, ESC was still under 110.:027: The motor temp were getting a little high at 155 or so. After the first pack I changed the gearing up to 24/70. ESC still stayed nice and cool under 110 and the motor temps came down to 135-140 or so. I probably could have gone even taller on the gearing, but that was all I had with me. Toward the end of the second pack I wanted to see if i could get it hotter so I did about 5 minutes of WOT runs back and forth in the taller grass field. I was able to get a reading at 142 right where the wires are attached to the board of the esc, but the aluminum case was still a cool 112.:dft003:
I can't even believe the difference. Not even a hint of thermaling. Thats just crazy compared with the 140+ readings from the aluminum case I was getting consistently before even with the lower gearing and having to stop to let it cool every 10 minutes.
I'm HAPPY:D This is the way its supposed to run.
