I haven't tried it yet myself...but I've heard of guys
using stainless steel fishing "leader line" with the
ends silver soldered to the connectors.

You'll need some small plastic tubing through the
fuse to use as guides. You'll have to eyeball and
alighn the tubes perfectly through the fuse to keep
the cables straight and tight.

On a plane that big you might want to use a "tiller"
arm....so that the strain will be on the tiller, not the
servo.
