Yes it does.
A local guy has a 70 type wing on his and its like its made of soft plastic and bowing in the middle like a swayback mule.
I spoke to one company who said they could make them with the higher quality pivots or something cheaper.
Some are using the original type materials and some are thin fiberglass.
First Place makes a really high quality wing. They cost from $399-499. You can buy them painted or not. I've seen them live and in person and they are very nice. Assuming I put one on "IT", I'll be using one of their wings.
