Looking for the part most towertalkians never use - that mast adaptor for mounting a Tailtwister rotor onto a pipe (as oppsed to setting it on a rotor shelf inside your tower) I have a gorgeous 4 holer for use with Ham-# sweries rotors but need one for the Tailtwister (5 - Holer) If you have one available please contact me. Thanks! Jim, K4OJ
