Will I figure i would be the first to say.
I have fried the first quark.
I don't know what happened.
The esc got to a hotest of 121 today.
I geared it up some.
It normally runs about the 110.
It had a problem from the start.
I talked to mike and he said it was not right.
Well it really is not right now. Blackened esc any one?

Not a very good birthday present :( That stinks leroy, im sure mike will figure this out! The temps your quark was running are colder than my 9920.

Sounds like it was just a bad one,hard luck Leroy.

How do you mean 'problem from the start' Did it do anything strange?

coolhandcountry · 06.16.2006, 09:38 PM

It acted like 2 out of 3 phases was hooked up. It only did this on first plug up of batts. If you got it to go it seemed ok. It was accually a great esc. I loved it. It was smooth and stuff after you got it going. I just don't know what was wrong. I guess I am going to see how the customer service is now. I know mike has good but have to see about quark.

Hopefully they are good because I want to use them for my 18T when I go BL.

I've had mine up to 145*F after about 12 minutes with no thermal shut down yet. I have not run mine very many times yet though. I like mine so far too. I hope the customer service is good for all our sakes!

I heard from Mike, that they had a no complain, replace kind of warrantee..

Seems that brushless still is too fragile.

coolhandcountry · 06.17.2006, 07:48 AM

I think it was something from the factory. It did it from first time to the lastime it smoked. I find out. It is going out monday.

Just wait for the Mamba Max, and that should change things!

Isn't the Mamba Max for 1/10 scale though?

squeeforever · 06.17.2006, 02:20 PM

Theres gonna be 2 versions. One for stadiums, tc's, ect. and another for Maxxes, ect...

MetalMan · 06.17.2006, 06:12 PM

The one that's coming out on Monday is the 1/10 version. The Monster version won't be out for a while still. I was merely commenting on the fragility of brushless.

I was just reading on another forum.
A guy had the same problem I was having on the quark 80b.
He said it was a problem with running 6s lipo.
Does any one else know if that is the case?
Will the 125 run on 6s lipo ok? I was thinking of getting another and see if it smoked but makes me worried not about doing it.

BrianG · 06.24.2006, 10:33 PM

Maybe it's possible that even though it says it's OK to run to 6s lipo, the voltage (~25v) is a little too high or maybe very close (if not over) the FETs' safe working voltage?

Or, it could simply be bad luck. There are bound to be a few released that may have a bad component or two. These ESCs have a bunch of paralleled FETs for each phase and if just one develops a short from the drain to source electrodes, then it could pass enough current to burn out a few traces rendering the whole thing useless.
