I was able to fly better today...
Had it under cotrol until d charge got over...dint break any props!  gt props n prop adapters frm edall hobby :thumbsup:
But wen in hover it keeps moving or wandering everywhr...
How to make it stay in one place? Wat would be the PID values?

Dont go to alter PI values now.
Trim it level, watch in which direction it is drifting, apply trim in that channel in opp. direction, till it is stable, perform this for 3 of the channels .

How is it flying with this values ?
If it is comfortable for you with this values, then there is no problem.

Wen increasing throttle it wanders everywhr... Doesnt stay in one place bt its controllable..

sooraj.palakkad

you need trimming to make it stable, also is your frame balanced ?

Flew it during night... Near my home..

VTOLkarthik

Oops it was in private all the time...changed

VTOLkarthik



Wen I fix throttle to 50 or 60 it wil lift off to certain height but it won't maintain the same height, it falls down but if I increase throttle even for little ir goes high...
any idea wat I should change in the setup?

Tried the Same thing today.. the hovering you mean ?

I did it via the trims :)

and I couple it with throttle cut to disarm the board.

Me too had this problem. Later found that there is a height dampening feature in KK board, I just tried increasing the value unti. my quad stopped altitude variation by it's own .

You can find the difference in here:
this is my first flight, I didn't tweaked the height dampening in this, you can notice the quad coming down on its own. www.youtube.com/watch?v=6FSuqgml5hI 

And here is the fully trimmed and tuned  stable flight with KK 2 : www.youtube.com/watch?v=ldRUtiPZzWA
