Anyone have any suggestions on a pull-pull arrangement that won't stretch?
Try using kevlar cable. I use it for pull-pull on the rudder of a 50cc IMAC model, approx 40 flights with lots of knife edge, so far no stretch.
You can get it as a Sullivan product, either a pull-pull kit or just the kevlar cable. I get mine from the Evil Empire ( Tower Hobbies ).
Good work on this thing, it's a fascinating aircraft.
Cheers
