One other thing that it could be is vibration.  Have you balanced your props well?

@f5soh:  Video shows that it gets off the ground without flipping, but wobbles / oscillates and is mushy.

This begins to sound like something I suspected.  Do you have ESCs 1-4 actually plugged into connectors 1-4 or maybe into connectors 3-6?  That would explain the wobble in a round about way.  Plug them into 1-4 rather than changing config to allow 3-6.

I re calibrated the ESc's and now its fine and i have attached the propler and one isssue is that its not taking off...just the motor spinning really hard and no lift is produced and i have attached the props in all possible combinations and not even lifting off from the ground.and i really need this to fly asap.Please do help

Bad ESC Calibration that does not run the ESCs at full power?

Props not tight?  Wrong prop on each motor so that it blows upward?  Dead battery?

Bad ESC calibration can do this.  Considering that you did ESC calibration recently, I would suggest recalibrating and make sure you use full throttle during calibration.  It is best to do it according to wiki instructions, using FC, not transmitter, so you know you used full throttle range, and got all ESCs calibrated the same.

If you put props in the wrong place, it blows upward, not downward.  Is it blowing upward?

It used to lift off.

That means it is either:
- tx stick not producing large enough signal
- fc configured to not produce enough output signal from the input signal
- esc calibration
- battery
- props on wrong somehow (e.g.upside down)

One last question.  Did it used to take almost full throttle to take off?  That will cause instability

Well, no need to start a new thread.
I see you go back to Gcs 15.09.

There is nothing wrong in configuration you posted.
We do not have a crystal ball to magically resolve your issue remotely :)
 
Post pictures from your build maybe.
