Is there a Quark 125B thermal problem?

[coolhandcountry]

I am currently running a 1512 2.5d neu on it. It is currently run with 4s lipo.
Yes I have trid 6s limn on it. It had a bad start up. After I got it going it was
ok. It was like had to warm esc up or wear batts down a little. When I say
start up. I mean like first hook batteris up and try to go. Not stop and go.
I tried 6s with a 1930 10t and it poof fried esc and motor. I have ran a 9xl on
it as well. I tried a xl 1200 basic. I have tried a 12xl as well. All the motors had
same issue with 6s. I went back to 4s and have had no issues what so ever.
I do get about 45 to 60 mins of run time on 8000 mah maxxamps pack. :D
