actually wat happend there are 2 problems
1. when i increase my throttle suddenly one or two or all motors stop.
2. if motors dont stop then when quad it going to take off then its rear part leave the ground first and frnt remain on the ground.
m using kk5.5 multicopter, turnigy 9x tx, esc = fmt 30a, 1000kv motor.
i think this is due to battery as my battery is not charging above 8.5v.

1.) Please tell the specifications of your battery.
2.) Is it a x-copter or a + one?
3.) Have you build your own frame?
4.) Your problems seems like, improper calibration of ESC's and potentiometers of your KK Board.

kk5.5 = bad choice. Quite tricky and the pots acts strange at times on it. KK2.0/2.1 is great for beginners as it makes life much more easier since it have the LCD and you get to see exactly what you're doing.
Coming to the LoPo, If you're using a 3cell LiPo then i have bad news for you. One of the cells on your LiPo is dead and most probably permanently unusable.

Watch some videos on Youtube about LiPos and how do they function.
and get a LiPo alarm even before thinking about getting a new LiPo. Thumbs Up

I too agree that if it is a 3 Cell Lipo and your voltage is 8.4V then one cell is dead. also there are a number of steps to be followed after flashing the kk board... i hope you have flashed your board properly using kkflashtool.. which firmware?
Secondly, have you calibrated your ESC's , stick centering, setting gain of gyros, etc... have you followed all these steps.
Also, kindly post a few pics.

Do you have a lipo battery checker or low voltage buzzer. if not get it ASAP. Now, it seems that one cell of your battery i dead. Check the voltage of individual cells using a multimeter. if it is 8.5 then you'll have to replace your battery. then, you need to first do stick centering, then calibrate ESC's, adjust your gyros... look which side it is first rising. now compare it with the direction of KK board that whether you need to adjust pitch gain or roll gain on kk board... also, do not put props unless everything is done properly otherwise you'll hurt yourself.

Firstly check your battery issue first. Replace it if needed.
Then try out the following link:
