Review for LEGO set 7171 Mos Espa Podrace from Brickipedia
“In order to increase the structural stability of the Podracer models, their design incorporates brick-built, sand-coloured booms that connect the Pods to the transparent parts of the energy couplings. These booms are not part of the actual Podracer vehicles within the Star... More Wars universe; they are a feature of the toy put there to hold the pods together. The sand color was chosen as it would blend with the Boonta Eve Classic's desert course.”
