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.

If you’ve changed your mind about keeping your purchase, please return it in its original condition with proof of purchase and we’ll exchange or refund it. Unless faulty, this should be within 35 days of receiving your order. By original condition, we’d expect this to mean that you’ve kept packaging and labels, and that the item is undamaged and unused.

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.

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.
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.
Three teams in my club (mine included) are currently working to perfect our forward intake catapults which we've dubbed our rampapults. So far, none have had much success. The two teams that started working on them a few weeks ago have struggled a bit but I hear they've had some success in making them work over the break. I just got my pneumatics in the mail today so my team hasn't built ours yet but we have it designed and ready to build, so we'll see how it all goes once it's built and running.

The VEX Catapult Toy helps you to introduce children to the world of STEM (Science, Technology, Engineering and Mathematics) through play. It has 100 pieces that are simple to put together and which stay in place for long-lasting models. This product comes with plans for three different sets, a race car, a trike and a catapult. The two balls provide ammunition for shots. Simply place one in the basket, crank the winch and fire. It has wheels that make it easy to roll around. You can use the parts to create models from your own imagination for even more creativity and fun. Use this toy to teach physics principles, as well as a history lesson as you describe how this Greek invention helped to modernize society.
