Default WooKong- M Problem

I'm having a strange issue with my Quad and WooKong-M. After 60 seconds or so the quad will slowly turn left and I have to apply rudder or trim to correct than another 30 seconds later it will again start turning left, I apply more trim. Or sometimes after applying trim the quad will make a very quick turn to the left almost as if I slammed the rudder stick the the left. Any thoughts on what may be causing this?

compass calibration? probably need more info like setup, etc.
But you may also want to post this on multirotorforums or rcgroups (although abit of a mess on the later). Lot's more wkm users there.

Have no idea, still trying to figure out programming issues with mine. Does sound like a compass issue though.
Have you tried re-calibrating?

I did run through the compass calibration again. From what I can tell the motors are aligned.

One motor may not be responding as quickly or has a bearing going out causing more drag, or there is a bad electrical connection to a motor, as it heats up it creates more resistance, and again one motor is slower than the others.

Ensure that all props are balanced as well. A vibration may be affecting the gyros..
