Default Trackstar 120amp and 6.5t modified v2 motor

I just completed installing everything and I have double checked all my connections.

My problem is my motor is smoking and very hot after just a couple seconds. I have the motor in factory settings running in blinky mode.

I'm new to electric and clueless as to what is going on. Any help is appreciated.

I even pulled the motor from the car and by itself does the same thing.

Trackstar 120a esc

Help.

Check and see if your solder connections at the motor are not touching each other.

There have been lots of issues with Trackstar 120A ESC. The good news is that HobbyKing will quickly issue you credit for a new one.
I had 2 bad ones in a row and decided to stop buying their stuff.

So it's the esc causing the motor to overheat?

I can attest to this issue. I've smoked two 7.5s and a 7.0. The only common factor was they were all Reedy motors. I currently run the track star 120s with a 5.5 in my 4wd and a 7.5 in my 2wd both Reedys and haven't had an issue. I have no idea what caused this as I still run the esc that this issue happened with. The motors would smoke make an almost dog whistle noise and be hot as sh!t in like 2 seconds. I'm not sure what you were doing when this happened but on two of the incidents for me was landing completely sideways off of a medium sized jump and then the car wouldn't move. As I walked up to it I gave a little throttle I heard the whine almost like the pinion came off then smoke came from the motor.

I eventualy figured out that the Trakstar connectors were poorly soldered.
I soldered on new connectors on the last one and it stopped cogging and ran ok.
Just use trakstar stuff in bashers now.
