Our team has had problems with our catapult arm snapping, and we were wondering how you guys made your cata arm and how you reinforce it?

Can you send a picture of your cata arm so we can know what’s wrong?

Are using using aluminum or steel?

Do you box your arm at the point of impact?

Have stable is your hard stop?

What do you mean box?

Boxing is when you either put another cchan across the current cchan, or put spacers and screws across that cchan to maintain the right 90deg bends and keep its over all shape

Yes we do do that.
