I have a restoration project going on a 1/3 scale bi-plane. It uses flying wires and turnbuckles by Dubro. As you can see in the pic the flying wire/turnbuckle assembly is very nice. I pretty sure the wire attachment was done with a Dubro Kwik Twist. I've ordered one. But have no idea how this thing works and what size wire the wrap, if it's a separate piece or if the music wire is wrapped around itself. Can someone give a short primer. thanks.
