Thank you. Your comment prompted me to test with the tricopter's hull clamped to my workbench to eliminate board movement and the tail arm didn't move at all this time. Chalk one up for newbie obsessing. The thing is that I only began to notice this recently -- probably because I started to get the hang of hovering (still no self levelling until I can upgrade the firmware) and began to look more closely at the copter.
What's the drawback of dialling down the yaw gain? More sluggish yaw response?
