Almost finished with my carbon fiber downscale Wildman Darkstar. Body is a carbon fiber sleeve from soller composites. I used a .25" stainless steel tube and some parchment paper for a mandrel. Fins are some carbon fiber "plate" I made some years ago. Two layers maybe? Today I went to hobby lobby and got some polystyrene tubes to make a cradle for it. Still need to do a streamer and lug for the rocket.
