Well its going to go backwards for a start unless you have a blue positive and red negative wire from your speedo for some bizare reason. Is the motor new? If not check the brushes, if it needs skimming etc, it could just be a sticky brush. Does the car roll when you push it? If not it could be something in the drivetrain or the motor.

No the positive and negative are the wrong way round, brushes look to be soldered ok. Did you skim/cut on the comm before you put new brushes in?

that would help.... to put wires right way. blue to the -ve and red to +ve.

also maybe just flick your brushes, they may be hanging.

No it won't make a difference, even if mounted backwards the motor should run. Besides, you only need to turn the can 180 to make it turn the correct way if the wires are soldered the wrong way around.

If you've recently cut the comm, Check that there is no copper dust in the segments between the comm's poles. Also make sure your endbell's 0 matches the can's 0 point...

Its a slim chance I know,but maybe its a dry joint on the soldering? looks like the wires might need tinning a little more.

If its making a noise like a high pitched noise then the motor has something physically stopping it from moving. Take the motor out the car and see if you can spin the main motor shaft. If its free try "pinging" the brushes, pull them out a couple of millimeters then let go, make sure the brush is sitting on the comm. Are the lights on your speedo working? does it have any? normally when you give it full throttle an LED will indicate this. If they are not. Reset your speedo (see manual)

Its not on the wrong side, you just have positive and negative reversed, so if it did run your car, it would go backwards...When you put them on the right way, try pushing the car forward to see if one of your brushes is hung up, if that doesnt work, then make sure the wire coming from your esc to your motor is not damaged or disconnected some how...
