Can aileron extension wires be used as elevator and rudder servo extensions as well? I am installing the servos for the control surfaces in the fuselage rear and need to extend the servo wires.

Thank you.

Yes they can. There is no difference in the servo wires for the aileron and rudder/elevator. The wire doesn't know the difference between two servos

Do be aware that you can have aerial shielding problems if you run your aerial in // with the fuz.

Also some RXs will pickup rf interference through long servo leads. The glider boys who use loooong extensions recomend rapping the extension round ferrite rings.
