Szilard Gyalay build our GBC 52 Flight Fair (made from the LEGO 42152 set) and got it working exactly like we intended it too. Great work on this and hopefully this gave you the inspiration to create your own Great Ball Contraptions as well in the near future :) He also made a review on our website (including video) for which we are really grateful. Thank you Szilard!
Here is his review:
GBC 52 is a new twist on moving the balls. The catapult mechanism is a new and simple one. I loved the incorporation of the propellers to “propel the balls” so all can yet again line up for being deployed. All in all a solid build, some fine tooling required. Motor speed needs to be experimented with. Because of the lunching mechanism design, used a stronger engine. Simple . low cost and efficient.
