So I have been thinking about a double catapult, but I can’t seem to find a video with a robot that uses them. Does anyone have a link to a video? Thx.

In honest opinion, I find it not useful to build a double catapult. The issue with it is the accuracy. Being a catapult, it may fire off centered if loaded incorrectly and not perfectly straight.
