Just wondering why glider are not made with pre-preg. Seems like it would save weight.

Having done 10 years working in Formula 1 making the cars solely from Prepreg and then another 6 years in aerospace making a payload fairing for a well know rocket launcher, I can say that the preconceived idea that prepreg is expensive is wrong.
You also don't need an autoclave to cure it

If you were willing to invest just a little money your raw material usage, and you reproduce-ability would increase no end.
Also, you could happily do a post cure on the parts and paint them any colour you like, just like in Formula 1.
