Step 4: Jetpack
Like the helmet, the jetpack is a bit of work but it does go together pretty quickly and making it from cardboard makes it very light weight. The missile is the hardest part to make. I made mine from styrene sheet but cardboard will work too. The body of the jetpack is made from cardboard glued together with a glue gun. After it's put together, the seams are smoothed with spackling paste and it gets a coating of polycrylic sealer before priming and painting. The jetpack is screwed to the armor backplate with four wood screws- you'll see in the photos that there are a couple of plastic sheets glued into the jetpack body to accept the screws.
The fuel tanks are made from soda cans and the ends are filled with hot glue and spackling paste.
My jetpack is still missing the thrusters!
