Not being a butthead, just helping you to help yourself.....
If you download Open Rocket, ( http://openrocket.sourceforge.net/ ) then get the rocksim file from Rocket Reviews ( http://www.rocketreviews.com/ ), you can figure it out with what ever materials you think you might want to use.
Also you would have OR for future design ideas...

Depends on what you build it from and how much nose weight you put in. Mine is PR fiberglass tubing and a Scotglas fiberglass NC with a fair amount of ballast in the nose, which in hindsight was overkill. It went 3300' on a K550. I'll throw it on the scales when I get home and let you know what it weight less engine and parachute.

Mine was heavily built using Flexible phenolic from Red Arrow Hobbies. Fiberglass throughout plus fins....Curtis nosecone....without the motor and noseweight, it weighed 11.5 pounds. ON the AMW M-1350 and the Gorilla Motors M1665, it got up to 8400 feet.
