My team and I are stumped on this one. 
we are trying to design a second launcher, but we dont know where to get started again because our first one failed desperately. would anyone care to give us a basic working design for a new launcher?
we would also appreciate a few tips on this: how can we get the Frisbee to spin as it launches? our first launcher had one wheel spinning at one speed at one side of a ‘tunnel’ and the other side is one solid piece of metal. we cannot get the Frisbee to spin.
Any help is appreciated! Thanks
