Stock wheel
The standard kit wheel is likely what you have. Simple and effective. You cannot push the plane backward or it will wrap up the chains. Cables are loose , but the link cables and chains are what sets the control sensitivity. I have found this to be one of the best controlling tail wheels ever. Make sure the wheel is installed correctly and perfectly vertical. Some tail springs become loose or where drilled incorrectly. Install a new tire if it's more flat than rounded at the tread. They are solid and require no air. With the plane sitting on ground the chains and cables should have a slight amount of slack, but that's it.
