Yaw Behaviour with F450 Frame and Arducopter 4.1.5

hi there

i have new f450 build
it seems that yaw response its a bit strange then other builds i have .
when i release the yaw control of my transmitter when it reaches a full turn, however the drone keeps on
turning for 1 sec and not response as the other axis that stops immediately after release the stick .

which parameter do i need to change for better “sharp” response?
thanks in advance
