“One of these is the new Surface Space Loader LT78, which will help any space mission from research to cargo loading and more. This intergalactic Space Loader LT78 comes in at 435 pieces and will feature a transport that measures 8" long, 7" wide, and 3.5" wide. Space... More travelers will be allowed to steer the loader as well as use the crane to help pick up and move around important cargo. Be sure to also be on the lookout for more LEGO Technic sets, as LEGO has included a special space air-lock that will allow master builders to connect to other space sets.”

“ome things make it awesome, like the windscreen and the new tires. The mechanism to raise it is fun. But overall, I don’t think it’s Technic’s best. I’m left wanting more and feeling like it’s not nearly as cool as its large counterparts. There’s only so much you can pack... More into a small set, compared to the heavy hitters in the wave, yet I’m not so sure I want to resign to that thinking.”
