smoked!!!!
 

my quark 125 burnt out. I didn't actually see smoke let out but sure does smell like burnt popcorn. I've only had it for about 2 months and there were no signs of problems. My temps were around 100 and motor 160. All of a sudden the truck got a burst of speed flipped it backwards and hit so hard that it bounced back forward. OUCH!

Any of you know if there is some kind of warranty?

Sorry to hear that. Mike said they (Quark) have been responsive to warranties & service.

Yes, Quark takes their responsibility when it comes to warranty.

You got yours thru Mike?

sure did
