Hello @Musharaf welcome to the community,

Are you doing that without props, on the ground?

Have you read How to methodically tune (almost) any multicopter using ArduCopter 4.4.x section 2.16 already?

Yes i have read that whole procedure

Please do answer all the questions.

5

yes i am doing without props on the ground,

Section 2.16 explicitly explains that those tests do not work and that the results will probably never be what you expected.

Please read it again.
