Literally all paper. I took 2 sheets o' construction paper, arrr, taped them together than usin' 4 mini engines taped together as a guide, I rolled t' airframe. T' engine mount is just t' airframe itself with a pm engine block I made out o' thinned out cardboard then rolled into a ring. Ahoy! T' fins are from flaps o' a cardboard box, I soaked them in super glue t' reinforce them. Begad! Then I rolled t' nose cone, put a small nail and more glue in t' tip for weight, and just taped it on, tried separation with shock chord recovery but shock chord got stuck inside t' airframe. Ya scallywag! So I'm goin' t' give it an oversized engine hook t' have t' mini engine ejected into it t' give it a tumble recovery. Arrr! Didn't expect such a good flight from it.
