What I want:

I want to build a system with power supply. For avionix one and for engine other.

What I have:

ArduIMU flat v2 code 1.7:

(http://store.diydrones.com/product_p/kt-arduimu-20.htm)

ArduPilot v2 code 1.6:

(http://www.sparkfun.com/commerce/product_info.php?products_id=8785)

ArduShield v2:

2 servos

And power supply:

LiPo 6Ahr/3,7 v

Problem:

Then I've soldered all modules I have aproblem. Some time servos dosn't reflet for IMU change position.

And If I tern it on fist time everything works ok.

But then I push restart or power off/on - the servous dosnt reflect for imu change position.

Why it happens?

Should servos reflect with IMU whithout GPS lock?

Do I correct power supply?

Is power 3,7 v enougt for it config?

Thanx for any answers/comments

PS 

Yellow circle - pin 13 is off on Ardupilot

(made by this recommendation: http://code.google.com/p/ardupilot/wiki/Upgrading)

Red circle - "Mux" led isn't on - is it ok?
