Hi

Whats the issue you are facing?
KK2 is a pretty easy FC, with most of the setup details online and other than tuning PI/Mixer editor settings rest of the stuff is easy from a beginner's POV...so just let us know your problems so that we can help you out from here.

Please explain in detail what you did till now and where are getting stuck, post a couple of close-up pics of your setup, mention the items you are using.

Initially I was facing problem with rolling over of my copter when I am trying to lift it. Later after enabling Self Leveling this problem is solved but I still cant lift it without Self Level enabled.

The problem I am facing now is it lifts but moves towards one side and it is not easy to control it. I have checked the reciever signals in the KK2.1 board. They are all in zero when idle. Any help?

Thanking you in advance

Fly High



Check motor allignment
Check trim settings
Check prop balance
Check for motor to motor length if it is self made frame
Check whether board is mounted parallel to the ground or not

And what ever you done correctly there is a limit what kk2.1 can do
In stabilize mode you will get good stability but in mannual normal mode you must control it a  bit...
All the best

If you want to fly in Acro, you need to be a good pilot, and take off quickly, otherwise due to ground effect your quad may become unstable. And nothing wrong in taking off in SL mode.

If your quad moves towards one side when sticks are centered, then what you can do is offset it in Self Level settings by changing ACC trim Roll/Pitch .If its rolling right,then use negative value and if its rolling left then add use positive value. Similarly if its drifting forwards the use negative value, if its drifting back then use positive value. Just increment values by 5-10 points each tine till you achieve stable flight. OR recalibrate the ACC again on a perfect level surface.

Re:

Thank you all.. I am able to get it stable to good percentage compared to what I had by changing the self level settings. Still some fine tunning is required.  Due to rain I was not able to test it properly.  Will try to do that will let you.

Thanks a million...
