Well guYs. My slash and tqi worked perfect, didn't drop or anything,then next day nothing at all. No led light or nothing. So I called traxxas they said I've had it for 3 months nothing they can do. I've seen where people been having problems with firmware etc. I checked I getting power up through it just not working. Power all the way to circuit board. Solder joints and they way circuit board looks like a 3 year old put it together. I think the top of line controller from traxxas should last longer than 3 months especially when firmware keeps crashing. This has me so mad I canceled my summit order now I'm thinking about selling off all my traxxas products if it's all just gonna be slapped together crap. I don't want to but I just went through making all my cars run off this controller. And I need help.
