I extended the rudder with a piece off a wrecked Hobbistar. I split the elevator and used a "y" pushrod. A Sullivan tailwheed assembly was easily attached to the bottom of the fuselage with the spring actuated from the bottom of the rudder. It works real well. I moved the main gear up to around the leading edge of the wing and used a Dubro plastic landing gear. It's ground handling is steady as a rock, and a lot of fun for shooting touch and go's.
