another burned quark
 

it finally let go. i was running 5s lipo today at the track and after the 2nd lap the truck slammed on the brakes mid throttle. i attempted to reprogram the controller with success, but it still wouldn't move. it just cogged really bad. i cut it off and tried giving it throttle and it let out a sizzle and smoke. this sucks really bad, i have(had) a race in two days. i can't bring myself to say one good word about this controller! guess i'll send it off for repair. i will be really pissed if this has any ill affect on my lmt 1950! heres a links to some pics of my baby:

I hope the motor survived as well but Coolhand_country had a motor damaged with his quark 80

he's my reason for worry!:026:

I can't really tell, but did you do the Opto mod for the Quark?

That is one NICE setup you have there, i notice you set things up in similar ways I do... ;)

Did you use thermal epoxy to bond your heatsink to the esc?

did the opto and used a ubec and arctic silver. my 12020 is fine, but has no midrange throttle. i need to send both of them off.

lol...12020 has no midrange? Well, I guess that wouldn't affect the way I drive ;)

Wow...two ESC's that dont work...and expensive ones at that...that sucks.

I always thought the 125B's were super reliable...maybe time to look at a MM? Seems like a good replacement for now...someone was running his on 5S...

The 12020 will take forever to get back FYI! BK is having issues with repairs and controllers right now, not sure why.

The service of S&T is perfect. Let's hope your motor is still among us..

Yeah, they have awesome CS!

I just got a replacement for my fried Quark 125 back. They replaced it no questions asked as long as its still in the 120 day waranty. Total time including shipping was around 2 1/2 weeks from when I sent it until the time I got it back. I sent them a white wire version and the sent me back a neon colored wire version back.

BTW my 1940/7 survived the burnout no problems. I was running the 1940 in another model on a diferent quark125 I have. No problems. I wouldnt get to worried.

do you think S&T would send me some white wires free of charge you think? I really don't like the 'fruit-cake' color wires on it now.

120 day warranty? I thought they have a 1 year warranty.

Real men do not fear neon!

LOL, hahaha

I'm sure you could even ask Mike for some wire too.

My bad.... Its 180 day according to the back page of the manual.

i'm well passed 180 days! will they just repair it and send it back? also, the motor seems ok. i hooked up my 12020 and everything seems ok on 3s lipo. what about my ubec?

Let us know how it goes since past the warranty date.

Good news on the motor.


Don't know about repairs outside of the waranty. You should call them. they answer pretty much any question I have ever had. They told me mine was ''unrepairable'' and just replaced it outright. I don't think they are set up for any real repair work. Just replacement stuff. You might ask them if there was any core value to the burnt controller. They may give you a discounted price on a new one.

These things come with a 180 days warranty only? this is a big disappointment..

And what if you are over that by a tad? I got mine back in July, and thought about sending it in.

i hope it is out of warranty, that way i can be done with "QUARK"! this thing has been nothing but problems since day one. first off it won't handle 6s and doesn't like to handle 5s. secondly it randomly resets itself, which is dangerous when using the built in lvc and lipos! guess i'll have to send off my 12020. i tried a few laps at the track running the 12020 today and it runs at very low speeds better than the quark. after 1-2 laps all the midrange throttle went out and made it extremely painful to drive on the track. maybe the mgm 24160 is the perfect esc, i don't care how tough it is to program as long as it works properly!

Wow, it really sounds like you got a lemon. My Quark has VERY good low speed control and I've never had it "reset" on me. I've run up to 16 cells, so I'd imagine 5s would be about the same.

If you decide to get it fixed under warranty and decide you still don't want it, let me know and I may want to take it off your hands.

i'll send it in for sure. if they fix/replace i'll let everyone know! help me remember that you want it and i'm sure we can work something out.

Will do, and good luck with any future ESCs! Although, if you get your Quark back, I would give it one more try real quick. It really is a nice ESC despite the cooling and 6s issues...

i will take pics of my wiring to see if everything is perfect, when i get it back
