- From sheet C, release the PM (Propulsion Module) TRUSS, but be careful not to cut off the four tiny black tabs at the apexes of the triangular struts. These tabs are located right at the release points.
- From sheet A, release the two halves of the HELIUM TANK. Join at right angles. Insert its cross-tab into the x-slot in the middle of the solid triangle on the PM TRUSS, so the tank will be on the blank white side. Secure with glue, making sure all the surfaces are at right angles.
- The four triangular segments of the PM TRUSS are joined by hinges. Crease the hinges to form a rectangle with the letters "PEP" on the outside, and HELIUM TANK on the inside. Position the two cross-hatched tabs into the ears, bend them over, and secure with glue.
