I've recently gotten into cardstock models. This was my second attempt and I'm am fairly pleased with the results. It is about 3 1/4" in diameter and about 22" tall. I did some modifications to the model to make it flyable. I laminated the fins, put some cardboard centering rings in some places for strength, and converted the paper tower into a wood dowel one for the better looks and for a parachute attachment point.

Here it is sitting in the yard



Here's the liftoff shot.
