Are the Traxxas ESC's really designed to handle 3s?
So I've had my brand new Stampede 4x4 VXL for about a week. I've ran it a few times on the supplied 8.4v Nihm battery pack, and 2 times on the 2s Lipo that I have. It ran fine...it's a new truck, so I'm just cruising it around....trying not to run it hard and break it just yet.
Well, I decided to give a 3s lipo a try tonight.....even though I know if I run it hard, it's going to break parts. So....I just ran it up and down the street a few times..probably around 1/2-3/4 throttle. I ran if for around 2 min, when I noticed the motor started cogging really bad when I wanted to take off. So when I pulled the body off to see what was going on, I noticed that the ESC was puffing white smoke, and super hot!! The motor wasn't super hot, but it was warmer than normal. After it cooled down, I plugged the battery back in and the ESC instantly started smoking again.
I called Traxxas and they are going to replace the ESC and motor just to be on the safe side. But it stinks that I'm going to be out of a truck for a few weeks.....oh well.
So are the Traxxas ESC's really that weak? Why would it cook when running a 3s just for a few minutes under light throttle? The thing is rated for 3S...it should take the higher amp draw right?? Not sure I ever want to try a 3s again after I get my new ESC and motor back.
Did I just get a bad one? Or are the Traxxas ESC's just that weak of a design?
