i m making a quadcopter using kk v5.5 flight controller. connections are as per directed in manual but still facing difficulties in arming and disarming ..what should i do. esc gets callibrated successfully and motors respond to throtlle but not to other sticks. 
thanks sumit.

Hi Pawan... what set up guide are you following and does the board arm sometimes? Also which part of India are you at?

setup was fine..i flashed board with v4.7 and those issues are solved. But now one of the motor stops after i increase throttle 50%. what should be the final cross checks before first flight? thanks.

If one of the motors is cutting off post 50% throttle, in all probability it is an endpoint issue with the esc, re-calibrate that esc-motor set. also if you are facing trouble with arming and disarming it again could be an endpoint adjustment issue. Try increasing the endpoints for the rudder channel to a higher than 100% value, most TX's allow for.

i am a biginner in quadcopter...and this is my final year project. can you help me how to configure the kk board v5.5 for quadcopter
