RE: Build your own PBF (Pizza Box Flyer, Flying Pizza Box)
the only reason i was suggesting the styrofoam is because thats what I had. the coro board is harder than you think to come by at least where I live. I finally found a little sign shop next to where I work who sold me 3 sheets 24 x 36. the coro was a little more expensive then I originally thought it was going to be, It cost about 6 dollars a sheet for 24 x 36. BUt never the less I got some and I will make it now according to plans. I will have spare to if I crash it to bad.
