In Joe Walker's #2 Fantasista (Contrasista) I could not mount the "frudder" servo as shown because we are using an Adverun drive which doesn't allow room for the servo in the fuselage. I therefore mounted the servo in the "frudder" itself and the output arm is fixed to the fuselage. It worked quite well and the "frudder" is quite solid possibly more so than the shown method which I used for #1Fantasista.
