hello guys
                i have constructed my quad using a kk2 controller board . . when i give it a little throttle the quad begins to vibrate rapidly .. can anyone help me with this issue ?? its urgent

Bro do you have any video?

nope ! it wobbles even before it takes off.. i try to get the video

is theere anything like the standard PI values for quads

The default ones that come along with quad is standard PI values, if it wobbles rapidly then decrease the Roll/Pitch gain.

Make sure the board is physically oriented according to the mode set in the software.

if +, then board points to one prop
if x, then board points between two props

can u roughly say how much do i have to lower the values ??

So here is the thing, keep increasing the p value the moment you get a high frequency wobbling. And once you get wobbles start decreasing the gain until the wobble is gone..

so you want me to decrease the P and I values ??

check this video and watch full video...

here i overcome another problem ...i have set the P & I gain values
 p-gain = 40
I-gain=30
 the rest are unchanged ..
the vibrations have reduced , but when i give it a 40 % throttle ...before the quad lifts itself , it drifts away towards its left .
what should in this case
