Build beyond the limit

October 11, 2022 October 5, 2022

Wow, just wow! Imagine our GBC 36 Crazy Carnival merged into our GBC 41 Power Pit Mania, but even cooler! Bennie te Veluwe (NL) did just that and created something beautiful which you must watch multiple times to see what really is going on. Thanks for sharing with us!

Have you also build one of our models yourself?
