Thanks @gunnu

The problem may be due to Improper throttle curve settings. Check 'throttle curve' setting on your Radio it should be linear (diagonal line from bottom left corner of graph to top right corner.) - If you don't understand what i mean, i can post pics of the curve on my radio setting.
Also check whether any unwanted mixes in turned ON on your Radio. If you are completely noob on radio settings, just Factory reset your radio, and try again.

@sooraj.palakkad
Kindly post the picks of settings.

Thanks and Regards

Here is the Throttle curve (This is on my Flysky FS-T6 radio, however the graph should be like this on your 9X too)

Is this ok?

Ok that is enough.
Now is there any improvement in flight ?

As I am currently using NAZA, i learned how to set it up I think I can help you better now.
If it is still showing problems, I would recommend you to clear the transmitter model memory , and do the Tx calibration again.
Do the sensor calibtration and try again.

I assume that all your connections, motor rotation, prop direction, Flight controller mounting is correct.

Thanks to all.

Cheers
