Re: What about a slingshot?
surgical tubing will last a very long time. It can be streached to 3 times its relaxed length repeatable without loosing strength, and without breaking
I use 100 feet of surgical tubing to launch my RC sailplane (6 foot wingspan). The tubing is at the end of 800 feet of nylon cord, and its pulled back 300 feet.
you would not want a slingshot that flaps loose like, well like a slingshot. you would want something more like a pinball machine shooter, using the surgical tubing as the spring.
the great thing about surgical tubing is you can easily double it up to get twice the force.
