Wire drive is what I always use. I make it 1,5mm thick wire for 380 and 540 size motors. Don't solder the wire to the strut , use Locktite 638 , way better and ultra fast. it only needs 15minutes to dry and you're ready to go.

If you descide to put the wire away from the strut just heat up the wire and the Locktite melts again.
