I purchased Van's new Tow Bar Kit for the RV-12.

It works as a tow bar, and as a rudder control lock. Seems to do both very well and is light weight. Minor assembly is required, and two holes get drilled to custom fit the rudder lock function (Since pedal height could vary slightly from plane to plane.)
I think it was a good solution.
