Quark Question

[cart213]

I don't think that it is the lvc causing the problem. I've got the same problem, and I have been using the NiMH setting on the quark.

I think I remember reading in the manual that even though you pick NiMH type, if you have ever set the voltage cutoff, it will still be in effect even though you are no longer using Lipos.

Hmmm.... I remember reading that too..

Try calling Quark Direct. I had some questiions and they were very helpfull on the phone. They will help you figure it out. Im sure of it.

Let us know what they say.

thanks man. Did you talk to them about yours?:032:

Yes. I called them a while back when I was trying to figure out exactly what the "torque" setting was and how it worked. I though it was like the "timing seting on the mamba25, but it turns out its more of a current limiter according to the guy at quark. The Lipo High and Lipo Normal setting is also a current limiter, but with more of a hard cieling as I understood it.

Anyway... Yes, I talked to them directly. Yes, they were very helpful and took plenty of time to help me work though my issues and even asked me to call back and let them know how it all worked out after I got a chance to "test" the changes they recomended. Seems to be a very good company.

That doesn't make sense, if the LVC is in lipo mode even if you pick NIMH it would almost not run due to lower voltages, unless you run way higher voltages to overcome it. Glad i didn't jump on the bandwagon when they came out, I think i'll stick to castle and mamba at any price

That is the way it reads in the manual, but there has to be a way to return it to stock so you can use the other settings. If not Quark made a serious programing misstake :032: and should make right on it. Hopefully you wont have to send it back to get it corrected. Give them a call they have a good support line. Let us know what they say.

crazyjr: Yeah, there does seem to be a few issues with the Quark. However, if no one ever got on the bandwagon to find these issues, no one would ever know. :) I still love mine and it works great. Even though people have been having good luck with the MM, I feel a little more secure in the fact that there are quite a few more FETs on the Quark to share the current load. Would I buy it again? Maybe not now that I know how the MM works, especially for the price.

smhertzog: Yeah, the manual does read that way. It is confusing. On one hand it does say that changing from Lipo manual (and then setting the manual level) to Lipo automatic won't change the manual setting. It does not explicitly say anything about what happens when switching to NiMH though. Logic would dictate that any NiMH setting would disregard the manual cutoff settings, but you never know. So, to be sure, I'd set the manual cutoff to 2.2v. For 12 cells, the ESC should "see" that as 4s lipo. At 2.2v/cell, it will cut off at 8.8v (2.2 X 4), which is probably good for 12 NiMH cells. You'll surely see performance loss long before you get to that level. For 14 cells, it might see that as 5s, and cut off at 11v (2.2 X 5). See how that runs. If all looks good, you might then try setting the battery type to NiMH normal/high and try it again.

I agree, I'm the type who will wait and see what happens as far as buggs. The only reason i got a mamba max so quick was i was reading everything the betas were posting and never saw a problem with them
