Building a Lego Tank that Shoots Lego Soccer Balls

Подробнее о видео

My attempt at a radio-controlled Lego tank that launches Lego soccer balls (= Lego GBC balls) using a rubber band powered gun. Nothing special in the hull, tracks and suspension. Many other Lego builders like Sariel, Kelkschiz and Matze Glatze have built better Lego tanks. But the gun is pretty powerful. I've never seen anyone make one that shoots soccer balls or uses a long wind up string to arm the rubber band. Theraband Gold was my choice for rubber band (very popular in real slingshots). The result is a bit dangerous. Not for kids! Use eye protection if you ever try to make it. The video is edited in retro 70s style with funky music. Enjoy!
