Can you copyright a paper airplane design?

I’m thinking of start a paper airplane section on my crafts website. The issue is I’m not areodynamic engineer and would use models made by someone at some point in time (recently or in the past). Can you legally put designs of paper airplanes on your website without violating any copyright laws?

I would be making the actual graphics and\or video tutorials myself and have my own unique web design with my own instructions in my own words. Any Ideas?
