GBC 45 Stunt Circus is a massive and creative Great Ball Contraption module from PV-Productions. Like for other PV-Productions builds, this GBC module can be entirely reproduced thanks to the parts from the official LEGO set 42100 (“Liebherr R 9800 Excavator”). This enormous marble run machine is an assembly of several individual but creative smaller modules: several lifts, a shooter module (which kicks your favorite LEGO GBC Balls in the air), a ball splitter, a turning table and many more other sophisticated sections interconnected via ramps. The complete build can be piloted from your smartphone via the LEGO Powered Up app (included within the Excavator LEGO set). And this awesome creation can even be extended with some PV-Productions accessories like a funnel or a 360 degrees loop. If you are looking for an alternative build to the LEGO Excavator kit, this massive GBC is made for you!
