Hi Dharmik,
I built a quadrotor recently with hobbyking kk board v2.1 shown at the link below.

My quadrotor is doing take off and landing as usual and i am using firmware minsoo kim 2.5 but i want to change it to kk 4.7 version since the quad is not very stable. I can't keep it hovering at a single place as you are doing in your videos. Please guide with the 4.7 firmware me so that i can achieve such stability in my quad copter.

Regards
Rahul

Hi Rahul bro,
Sorry for late reply. I haven't tried minsoo Kim's firmware but you have to tune your quad to get stable flight. Try increasing P gain and decreasing I gain. KK 4.7 has ability to adjust both gains separately but it requires to reverse gyro gain. I am using KK2.0 LCD version. Please let me know if you need any help.
