Good to know you don't know how to Google search. You obviously got something wrong, because if you look around instead of assuming like most people on this forum, you'd know that you can absolutely fix this issue.I've had the balance rings for a while and the gimbal still drifts even when perfectly balanced with the 45mm. I think it's just the nature of the gimbal. Mine drifts very slowly from right to left or vice versa.
I fly dual operator 90% of the time so my partner is usually correcting it himself. If you fly single op, just make sure the C1 or C2 button on the back of the remote is assigned to reset yaw.
But I'm tired of spoon feeding stupid here... bunch of amateurs.
