I've checked all the below and are correct.

- is the software configured for X and not + copter?
- is your "front" orientation correct on your board?
- is your board mounted right side up?
- do you have the CW and CCW props attached to the correct motors?

I've checked the manual from kkmulticopter and http://rcexplorer.se/page14/kkguide/kkguide/quad.html
