Try calibrating the ESCs.
Change the minimum throttle in your kk board to higher value.

Vtol, whats the update? Have you calibrated each esc separately. have you set all gyros at 50%. Please post a video of whats happening.

I have calibrated ESC's seperately but wen i run the motors with prop off each motors start at difff time...ill test it tomorrow and then ill post the video... can u tell me how to do the stick centering?

Yup, what radio do you have?
change the subtrims.

I have sanwa SD 6G... I know trims, its thr on display...I dint get the subtrims...whr is it?

OK I got it figured...yaw pot was reversed...so wen i turned it to min i was making it to max...so i was unable to calibrate ESC's with kkboard...
now all the motors r starting up at a time...
Ill be testing it today n post the video...
Can anyone tell me how to reverse the yaw pot...?
I get confused wit one pot reversed and others in normal
THANK YOU

here is the video....

I was the only one in terrace so i had to handle the Tx and also d cam...It dint come out well
but later without cam i tried to fly it went all over the place n neatly swept the whole place....

I'm glad you are making progress Vtol. Please do all your testing in an open field, crashes will more forgiving and you will have more confidence inspiring flights as you don't have to worry about hitting something.

thr r no much open fields around...one is too far...n just for 10 min flight i cant go thr...so wanted to hover perfectly n then go to a open field n fly it..

here is my first flight
It was really awesom!!!

Nice. But i guess balancing/acc calibration issues exist. All the best.
Cheers!

ya i need to tune it.....
i ahve taken another video...it was stable in it...
ill try to upload it
