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.
Alright guys over the months I have seen countless catapult designs each with their perks and then theres some that are just plain disappointing. Theres the forward catapult, backward catapult, the full arm catapult, forward intake catapult, backwards intake catapult. There are several more I dont remember at the moment. Which catapult do you guys believe is best and why?

The positives to a front catapult is that you only need half of everything because the degrees of motion is basically half of what a backwards catapult is. I've only seen backwards catapults with 4 pistons and only front catapults with 2 pistons. Does that mean if someone gets a backwards catapult with 2 pistons a front catapult would only need one? :eek: Probably impossible if you're following the rules on pressure. The front catapult can also actually act as an assist to get big balls out quicker so you don't have to wait for intake to spit it out or if you can't get the ball out of your intake at all. I've found this to be helpful.


My son received this as a birthday present when he was 4 years old. He was able to build most of this himself, with me reading the instructions for him. He loves playing with this and often takes it apart to build the car and different versions. Since then, I have ordered additional sets to give as gifts to his friends who are turning 5-10. This is a great alternative to Lego. This holds together very well and does not fall apart when he or his friends are playing with it.

The catapult will capture the attention of many kids and when they see how it launches balls, they’ll cling to it. However, on the exact same note, it might be a little hard to set up in order to get the ball to launch. Children will need some patience in order to get it to work, but it is well worth it since as soon as it works, the youngsters are going to be impressed with how it carries out.
My 8 year old built it in less than 20 min without my help. I didn’t even know he opened it. I was doing laundry and next thing I knew we had a catapult at the kitchen table. Didn’t ask for help or anything, no extra pieces. Too simple but worth the price I guess. It was one of the cheapest options I could find. With our local team going to worlds competition again he wanted to see what VEX was all about.
