I built one pretty much stock a few years ago - printed it on 110# cardstock and I never had any trouble with the rear end bowing into the exhaust. I used the Yankee nose cone (which is a pretty close approximation of the original) and 1/4" foam core for the fibre board bulkhead. It flew fine until the cardstock started warping from age and gravity (time is not kind to cardstock models). If you use the plastic nose cone, you'll want to get some self adhesive label stock and stick that around the shoulder, then glue that to the body tube. Mine held up fine to the ejection charges.
