“The parts provided this time are the inner and outer casings for R2-D2’s right foot, which cover most of the motor and wheel. These will further be enclosed by the casings around the underside and the fuel cells at a later [issue]. You also have the mounting plate for the two powerbus cables that connect the foot to the fuel cells.”

After the huge last issue, this one is going to be easy!



Materials: Everything in this issue is plastic.
