i have quadcopter with following specification:
4x kv1000 bldc motor
4x 30mah esc
lipo 3000mah battery
openpilot cc3d flight controller
..after giving full throtle also is unable to lift it. the propeller are also in proper direction of rotation.
1 & 3 in cc & 2 &  4 in ccw
please help me ...

It would be very much helpful if you post a video of your quadcopter.
1) Do you feel any increase in motor speed with your throttle.
2)what is size and weight of your model.
3)what is the propeller size.

propeller of 10x4.5 sizes 2 are cc and 2 are ccw
i will upload within short time

video of my quadcopter in which we can see the exact problem plz help me

@shelake,
SAFETY FIRST.
DO NOT HOLD THE LIPO LIKE THAT.
IF THE QUAD LIFTS OFF, YOU'LL BE IN REAL TROUBLE.

Next:
Please approach the problem by analysing your observations, and using data. And unless you share the data, others cannot help.

Observation: Not lifting.
Likely reasons, a) not enough power, b) too much weight

If not enough power:
Likely reasons, a) battery voltage and/or current providing ability not enough, b) motors too weak

To proceed further, you have to tell us:
1. The number of cells, and C rating of your 3000mah lipo. Are you using a 2cell lipo where a 3cell lipo is required?
2. The wattage rating of your motors (pl mention make, model number etc)
3. Are the props the ones recommended for these motors?
4. All up weight including battery.
5. Whether you caliberated the throttle?

REPEAT CAUTION:
Pl attach battery to model. DO NOT HOLD BY HAND, ESPECIALLY ABOVE MODEL.
Why is the battery not on the model?

@shelake,
ARE ALL YOUR MOTORS/PROPS PRODUCING LIFT OR DOWNTHRUST?

I've seen this once before on RCI. Never expected to see it again.

Your ESCs look to be completely out of sync.
Follow the steps below.
1) Calibrate your ESCs.
2) Check the ESC-FC wiring.
3) Check if you have selected the right Multirotor type.
4) Check your Remote mixing.
5) Never Ever, EVER hold a lithium polymer battery like that.

It looks like on of the motor rotating in wrong direction or left red arm motor is not in synchronisation.
1.Check motor spinning directions
2.Try to calibrate ESCs
3. Calibrate accelerometer and gyroscope.
4. Try flying in open field in grass so that you have much room to play.

sorry for keeping battery in hand
yes sir i will take care about it

battery 4 cell 3000 mah zippy lippo battery
propellers  10x4.5 inchs     2  cc  &   2  ccw
i think they are in write direction
i will calibrate the esc and after that i will check
please help me for callibrating the esc

thank you
