11 Servos on red back spider (ATmega1280), how to power?



I'm stuck! I am trying to connect 11 servos to the red back spider board, and as soon as I turn on the power (up to 12v) the servos all jerk and move like crazy and the board turns itself off again. 


I'm not quite sure what I am doing wrong or how I need to power 11 servos (9g micro servos) without the board crashing? 

Anyone can help me out?

From my experience micro 9g servos draw 200-300mA. If you are moving 11 servos at the same time you are close to the limit of the 5V 3A regulator on the red back spider. You could try powering the red back spider with a 2 or 3 cell lipo battery.
