i suggest to add new pictures for better explanation. I am new here so don't know a lot about copyright conditions so am leaving some resources that i found can help. airplane wings ^[1],rockets and missiles ^[2],and for model rockets ^[3]. I also recommend to add sections of model rockets if not here then in wikihow website it will make article more article more attractive rather than look more like a patent paper.Also only those who know about copyright enough should do this act.
