Shimmy
When I owned my Bingelis RV-3 it would shimmy in the 20-25 kt speed region while taxiing or after landing and lowering the tail wheel . It was happening because the springy gear legs wanted to track out then back in with the tail on the ground. It never happened with the tail off the ground. Solution was to put wooden stiffeners on the back of the gear legs and to balance the wheel pants. Once I did that the shimmy went away.
