Szilard Gyalay from the USA build our latest GBC 52 Flight Fair made from the LEGO 42152 Firefighter Aircraft set. Once setup correctly he made a nice video of it in action and even including an epic slow motion part where you can see the GBC Balls fly. See around minute 00:40. See also his review here below. Thanks for sharing with us!
GBC 52 Flight Fair - 42152 Building Instructions
Szilard Gyalay - December 7, 2023
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.
