Quark fried, blown capacitor... - RC-Monster Forums

I took out my Hyper 8 with MM, Neu 1512 2.5D, Maxamps 4s 5000HV, and 4-cap bank. Unfortunately the cogging was still there as before, but it didn't seem as harsh as before when it did occur (which was roughly 50% of dead-stop pulls of the trigger). However, I DID notice a difference in temps - the motor seemed to be maybe 10deg. cooler, the battery was a bit cooler, and the MM didn't even feel warm (although this time it did have a small 25mm fan). I can play around with the ESC settings to see if I can reduce the startup cogging.

That's interesting that your motor would run cooler, maybe it is switching from phase to phase more efficiently? Just a guess.

So i guess it does not help the MM with cogging the Neu motors, must simply be the software, and nothing but.

At this point though, it looks like it is for surely helping to reduce esc running temp.

Well, I got my Quark back today, surprisingly fast. :003:

It is raining today, so no running. I took it apart and tried to look at the capacitor markings.... the brand looks like it's 'SANNHA' 'WB' series. I have never heard of that brand, and I can not find a SINGLE thing searching for it.

I think S&T are having trouble with 'Quality Control', my new Quark has a few near cold solders. And the caps have burn marks all around from soldering them on. The middle motor wire does not have solder on the top half of the pcb, not good.

So I was pretty dang close as far as guessing the measurements for my custom quark case. Only .5 - 1mm off hear and there.

I will fix all measurements and post a screenie of the quark case.

Perhaps there has been an increase in popularity for the Quark controllers and they are having trouble meeting demand?
