you have given me two great ways! I have the cable ties right on my bench.as for a spring I am going to look for a source..yes I know there are many guys using rubber bands.I trusted sig a long time but it just un-nerved me when I can pull the wing aand it moves outward a bit.when I fly I want to worry about flying only lol..it's such an easy buiuld too.I got this one from a club member after he crashed it and decided not to rebuild it.thankfully he had ordered a wing kit and just gave it to me when I said I should get one.good tips thanks again..
