Scott Foster had this setup at the JR Indoor Electric Festival. His was Ikarus Eco 8 tail rotor on an AXi. Fly RC had an article about it. The first motor he did was a Typhoon micro 6. Hobby Lobby is suppose to carry the setups when they begin production. My frieds saw him fly in Columbus, and talked to him. He was willing to others have a try at flying it. Sounded like had a problem with the shaft wearing out.
