My 9 y/o opened his Mini Summit this morning.
He didn't get across the front yard before the ESC started cutting out.
This would have been a bummer had this been his first truck, but since he races, he totally gets it. He grabbed our 18 month old MERV and his toolbox, pulled the speedo, installed it in his new Summit, and is ripping as we speak...
The bad ESC will be sent back to Traxxas on Monday...
You have a speedometer in your RC's?

What is up with these esc's... Everyone seems to be having trouble with them. Traxxas needs to acknowledge there is an issue and take care of it. I had trouble with mine and did some adjustments on my radio that helped, but not %100... I have not talked to anyone that has not had this issue with the summit so something is obviously wrong.
For what I've seen here in a few ESCs, when they waterproofed the electronics, they put the transparent epoxy all over electronics and over the power transistors too... Then added white thermal paste and glued the heat sink to the power transistors instead of gluing them first and adding the transparent epoxy later to waterproof it... So, basically, it overheats rapidly because there's a thin layer of transparent epoxy between the transistors and the heat sink...

This is pure speculation on my part but I am starting to think Traxxas may have had a bad batch of the VXL-3m ESC, maybe they got a bad batch of a particular component from a supplier or something. This ESC has been in use for a pretty long time without having this issue.My thought is they ran a batch of them when they started production of the mini Summit and that is why the Summit is having this issue while it has not been seen in the other 1/16th scale cars that use the same ESC. Like it has already been stated if you are having issues contact Traxxas they have a great track record and will do what it takes to make it right.

Man did I ever luck out! I've been following this ESC problem in the forums for over a month now. Finally got my blue Summit VXL yesterday morning. Was already mentally preparing myself for the worst and a phonecall to Traxxas on Monday. But thank goodness mine turned out OK.
Sorry to hear everyone else's problem. I was totally ready to join the crowd. Just know that once its fixed, this little beast is S-W-E-E-T!
Actually I bought it at Thanksgiving, but my wife made me wait. Thats why I was so nervous, that was at the time all the problems were surfacing.
I'll keep my fingers crossed it doesn't 'go bad.' So far I've only managed 2 packs of run time, family visiting and all. Only issue I've encountered so far is the slipper clutch seems a bit too loose.
