motors dont run on multiwii quadcopter

[mathies]

hello,

I've just built my first MultiWii quadcopter.
My setup is:
Flight controller: MultiWii PRO Flight Controller w/MTK GPS Module
ESC: Hobby King 30A ESC 3A UBEC
Motors: D2830-11 1000kv Brushless Motor
Battery: Turnigy 3300mAh 3S 30C Lipo Pack
Props: 8045 SF Props 2pc CW 2 pc CCW Rotation

I have everything connected and uploaded the multiwii 2.3 software to the multiwii pro board.
When I connect the battery ther are 5 tunes and the leds are flashing but when I want to arm the motors, nothing happens. I tried everything but they wont work.
Is there anyone who could help me?

Greets,
Mathies

check if the yaw middlepoint are at 1500 if not trim the tx
and also did u define allow arm disarm via tx yaw

The yaw middlepoint is at 1500.
But how can I define allow arm disarm via tx yaw?
And after I connect the battery the lights stays flashing is this normal?

U can defined it in config.h
No it's not normal to leds to flash more than 20secs at least
For my boards
Did u calibrate ::acc &mag
