I am temporarily renaming the calvinball to "Justice".
I throw the ball into the air and smack it with a tennis racket so that it flies over the net and whacks @Scarecrow71 in the back of the head.
Justice... has been served.
Moar struts?
Seriously though, how much weight do the chopsticks have to be capable of holding, assuming the inertia of that returning booster? I'm thinking it's probably the strength of the fins that is the limiting factor
Umm... a thought... why not launch it directly from the "chopsticks", high off the ground, with no launch pad at all? The best part is no part and all that...
