Motor won't start

[Rb3]

i have a problem with my Qaudcopter. I'm building my first quadcopter.
Now i have done all the steps. But the motor won't start.

- Firmware multiwii 2.3 on my multiwii pro uploaded. (with the good setting)
- Calibrate the esc (so without the multwii pro the motor and the esc's are working)
- I checked all the connections to the receiver and they all connected to the good pins.
- When i put the battery on all the esc's are armed and i getting a green light on the esc's.
- On the multiwii pro there is blinking a red led and the green led.
- On the multiwii wiki i saw that you can stop the motor. So i followed the instructions: throttle down and rudder to the right to start the motor. I see that the red light on the multiwii pro is 1 sec. stopping with blinking en then he blinks again.

Have someone a idea why the motor's won't start when i move the throttle up?

Did you cal the ACC in the GUI??
Are the TX's Stick end points correctly setup in the TX menu?
Did you read the MultiWii WIKI, beginner's troubleshooting?
