Help!
Yaw problem with HK KK Board V2.1, KK firmware 4.7

Hi,

the controller mentioned above worked fine before, but was lying in its box for a while. Now I installed it in my H-Quad and started to test everything, when I noticed the motors only react to left yaw input and counteract right (CW) yaw rotation only. Pitch and roll work as expected.
I would be very thankful for any ideas.

Do you have 2 motors spinning faster than the other pair (aka lazy motor)? You might need to add some rudder subtrim until the motor speeds balance out. Check if you have some trim/subtrim on the pitch/roll, and add a similar amount for rudder.

what about a double check on the direction of each motor spinning?
