Smoke from the ESC, can't be good.
Last weekend I thought I burnt out my motor, I still think I did but now i'm not too sure. I had a Novak GTB Vloiciti 5.5 brushless system in my Losi Strike, made it two laps around the track and lost power, got to the truck and the motor was HOT, didn't get a temp gun on it because I didn't think there was a reason. I decided to buy a used 6.5 Velociti to replace the 5.5, that came in the mail today. I soldered up the connections to the motor, plugged the sensor motor in it and put a 6 cell pack in the truck and punched it and started to smell that burnt electronic smell. I thought first off all the motor was bad because I bought the motor used and then I punched it again and smoke started coming from the bottom of the ESC. I quickly unplugged the battery. The ESC was hot, really hot, the wires going to the battery were very hot, I could hardly get them apart. I checked the motor and it was cold, all the wires running to the motor were cold as well. It obvious the ESC is shot but my question is do you think it harmed the motor? I'm trying to decide if I should get another Novak GTB ESC or just something else. Any info would be appreciated. Thanks.

I personnaly don't like Novak. They always overheat. I would get a mmpro or Tekin RS instead. That is good quality stuff. Don't waste anymore time with Novak if you had many problems already.
I wouldn't think your motor would be affected. A motor only gets voltage and makes your car move. It doesn't do anything else. It should be fine.

drop novaktwo a message about the esc and see what can be done. Is it still in warranty period?
I would probably do the following in your case:
1. have someone else try the motor on there ESC to see if all is well
2. call Novak and see what can be done / or how much it is to send in to fix
You can try another esc for sure. If you find you are hard on stuff, I would go with the one with the longest warranty, and that right now is the castle Mamba Max Pro. For the money in comparison to other ESCs out there, sounds like you get a lot of bang for the buck.

Well now another turn of events.
I decided to hook up my motor that I thought was shot, the 5.5 and just run it till it quit. I ran it and it studdered for a second then the motor gained RPM's and the ESC stopped getting hot. I threw the setup in my XXXT and sure enough the power is back to the motor, the only problem I have now is once and a while the ESC studders when I hit the gas. I'm sure that the ESC is shot or about to die but I think the 5.5 motor that I thought was burnt out is ok.

Also, free revving your BL system can damage your electronics.
