got problem???

i am using a monster stock motor and all of a sudden my car seemed to be going very slow, then it needed to be pushed so the motor would start turning and now the motor won't turn at all.
anyone have any ideas? any help would be appreciated.
thanks

Have you checked the brushes and comm? Are they just worn and glazed?

Might be time for a comm-cut and a fresh set of brushes?

Could be several things causing your problem:
-A hung brush.
-Motor could just need a rebuild
-Loose wire on your ESC/motor/battery
-Motor could be bad

The first thing I would do is to see if the motors brushes are actually making contact with the com. Make sure that the shunts are not hung up on anything causing the brush to not make contact with the com.
Just give everything a good look over to make sure everything is in proper working order.

i looked at the motor and had others look at it since i am new in this hobby. they said it seems to be fine.
i have a xray t1r and i believe it is called a v12 speed control.
the speed control comes on and acts like it wants to work but nothing from the motor.
oh yeah the motor was ran in only 3 heats.

try another motor, if another motor works then it is a problem with the motor. if another motor doesn't work then its a problem with the speedo or electronics.

thanks for everyone's help. i put a new motor in and it seems to work fine now.
now i need to find out what is wrong with the motor since it has only 2 1/2 heats on it, and what would cause the motor to do this.

Sounds like you have a blown connection at the comm tab. If you look at the three connections you'll see the high-temp solder missing off one of them. You can resolder it if you were able to get some of that high-temp stuff.

You can spot welded with 1200 degree Silfos, a special material plumbers use for brazing copper together. It never comes off. But Mike Reedy believes this temp is too hot as it tends to anneal the copper plates making them wear faster, he says.


This a quote from "Big Jim" when I had the same problem with my Reedy TI 9x2.
