Recently purchased t-BIRD lightsport taildrager. Having problems when landing and tailwheel makes contact it starts to vibrate and flutter side to side causing loss of control.Anyone have any ideas?Shold cables and springs be tight or have some slack?Tailwheel does lean a little to one side when in sraight position.

castering wheel axis should be horizontal under normal load. as in picture .. There should be some form of spring to dampen out the enevitable rough movements. compression shown

My buddy mentioned his Yak has a terrible shimmy problem if there is "a little too much" weight in the back seat. I think he said the solution to it is a stiffer spring, but I am probably wrong. I thought he said he was going to put a scott tailwheel on it and that should fix it.

Jim is right ,..the axis point should be 90 degrees to the surface ,..but sometimes depending on the manufacturer of the tail wheel ,..the centering/axis mechanism get's plumb worn out ,..which allows the wheel to go into all kinds of camber caster positions,.have you checked the sleeve or bearing points( again depending on manufacturer) for slop?

Springs should have some tension. Caster as previously noted. Reducing the load on the tail will help also (stick forward to stop the shimmy, then reaply back pressure as able.). Additional suggestion, land on the grass. Wheel landings will help also.
