Quark email address.
 

I had sent an email to the quark address listed to see if there was anyone who would answer,after hearing that no one was.I received this earlier. Hi. Adam.

Just our US office is shut down now.

but Korea head office is still on the business .

If you need repair or support. just let me know through this e-mail address

Thank you.

Sky & Technology Co.,Ltd joejoepeace@gmail.com So I was glad to get a response from them.I received my Quark 80b today now I'm just looking for the right caps,I had seen someone on here had some for sale,or any ideas?

Hi Asheck,

This must be your lucky day. LOL

I've believe the Novak HV Capacitor to be one of the best ones for this.

Well guess what?

I found the EXACT same capacitor that Novak uses on Ebay, but for MUCH cheaper.

I ordered some and compared side by side with the Novak HV Cap.

Check this out: http://cgi.ebay.com/2700uf-Low-ESR-c...QQcmdZViewItem

Somehow it doesn't surprise me. Good find though.

I ordered several just to stock up for future mods.

One of these days, I'm gonna get a MMM. LOL

This seller sent my package quickly and it was well packed.

Well I just ordered a few also,but don't I want 35v for my Quark?

Most people suggest having some slack "overhead" voltage rating.

However, I have ran this Capacitor on 6S with great results.

These Caps are rated for 25 volts. 6S fresh off the charger is 25.2 volts. Close enough in my book. :yes:

I only really plan on 5s anyway so this should be perfect.So I ordered 5,how many do you think the quark warrants?

2 should be plenty.

has anyone gotten repair work on their quark esc this year. i've tried joejoepeace@gmail.com to no avail. i dont care how long it takes (other projects) but i would like it repaired
thanks

I've been trying that address as well with no response. If anyone finds something out I'll be interested.

You could try Quarks Korean support forum. It's still active.

You should get them on this..

Hey sikeston (or anyone else), do you have a model number for those Caps? I found THIS ONE, but i'm not sure it'll do the job. :neutral:

I'm currently running 16 GPs with my 125B, but I'll be running 5s soon.

Alien

hey sikeston, was that with the quark? Mine (125/80 quark's) has a slight cog or hesitation with a fresh 6s setup, so, would the cap/caps work and allow me to run 6s without fear? How are the caps setup and how do you like the quark on 6s?

The quarks were always twitchy with 6s fresh off the charger, not sure if the caps would help that really- a lower charge voltage (95% say) works wonders aparently.

As for the caps, dont go with the novak module, thats the one that has been blowing up on hvmaxx escs ever since they updated it. The specs you want are:

25v (or 35v), low esr, 105*C, 2700uf (I wouldnt excede about 6000uf if you use several in parallel). A few examples:

one

two

three

Thanks Neil... I will add those to my list. Will the 125B run well on 5s without ill effects? I noticed it's not the most favourite esc out there now.

Alien

The 125B runs great on 5s. I have that in my Ultra GTP and it runs perfectly fine.

And if you plan on running 6s, I'd get 35v caps. Yeah, 25v is really close to a "peaked" lipo (25.2v), but you always want a little overhead (I like ~15%). A little leeway stresses the caps less and there is always a chance of voltage spikes when braking.

Could this work? 35v 2200uF or is the 'uF' rating too low?

That would be fine- I'd use a pair in parallel for best performance.

The quarks used ot be popular due to good customer serive in the states, but the US office went bye-bye some time ago, and tracking down the Korean one is a bit tricky, as has been noted. Shame though, since the newer Quark Plasma escs look rather awesome....

I know neil, I was asking because i got the 6s twitchy ones. If the caps help, i might try them, couldn't hurt. I got three quarks, one 80 and two 125, while they may be replaced with mamba's or tekins, i got to make them last for now. but want more out of them and want to experiment with 6s setups. The 80 is on my GT conversion on 5s right now, I want to try 6s setup with the lehner basic XL 1200 kv motor. My G2R is set up with a 5s setup on a 125 w/2.5D neu 1515 (1600kv) I'd like to regear to 6s and 35-40 on a 3095 transmission. The other quark will probably find its way into my 8T with either the 2.5d 1515 or my 2250/10t lehner, if i go 2250 in the truggy, it'll need a big pinion even with 6s lipo's. I'm sure based on the surge ratings, the 125 can handle the 2250, just hope it can take the 6s without burning

The thought has crossed my mind to put the 2250 in the revo on the 3095 transmission, is has the mount holes already

so i emailed pjwan75@naver.com for 33 amp pro and they just said it would be easier/cheaper to buy a new "plasma speedo as it has replaced the quark 33 amp pro.....hmmmm well screw that, anyone want a dead quark 33 amp pro lol
