Steering servo arm for Tamiya Blitzer Beetle / Stadium Thunder. Most likely works with other Tamiya models with same type steering linkage. Note that this is only a part of the servo saver assembly and is not threaded to fit directly onto the servo output gear. Model has designed-in supports that will need to be removed before assembly.
UPDATED: the bushing that would normally be installed separately is now part of the design, which should hopefully add some strength as the part was shearing at the interface between the plate and the keyway.
