What I did notice, however, was that the ball had way too much power directed in the wrong direction - so I do believe that with correct geometry, a backward launcher could also be done with just 1 piston like John's. I know it's not clear what I mean by having a forward launcher geometry flinging backwards instead, but it's late, so I'll let Aaron or Ruiqi explain for me if anybody has questions.
It took us one hour to build this set. It is listed as being a beginner skill level build that can take anywhere from one to two hours to complete, depending on your skill level. The instructions were picture-only instructions and were a little confusing as were the picture directions for how to use the catapult. Also, the knob fell off quite often, but reattaching it was easy.
The catapult looks cool and does launch the balls really well, but it's also a little difficult to set up in order to launch, so kids will need to have some patience to get it to work. Once it does work, we think kids will be impressed by its performance as well as their ability to build this fully functional catapult. This STEM-based construction set makes a nice hands-on introduction to engineering, but we do wish it included more information on the science behind how catapults work and its real-world applications.

For our catapult design, we actually took inspiration from Aaron and 7090 in order to create the same degree of rotation as the forward catapults, but backwards. It was also designed to only catapult large balls, as many times it was more useful to keep the buckyball and only fling the large ball. Our season has ended until March, but we ended up not having enough space to have the actual deflection we wanted (60 degrees), and went with something more like 80 degrees, which was not optimal. To add to that, the trajectory was not tuned, so the ball would go much, much higher than we intended. As a result, we just decided to throw pistons at the problem (we had 5 single action pistons, equivalent to 4 double actions), to solve it quickly before our last competition. It worked well, but obviously not as well as we wanted it to.
