This modern Catapult has a ratcheting winch that can control the distance projectiles are thrown. Crank the winch to its maximum tension and you can hurl balls over 10 feet! This cool construction set teaches kids important lessons about variable shot power and how machines store kinetic energy. Includes more than 100 easy-snap pieces, 2 balls, and instructions for 2 alternative builds. 

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?
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.

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.

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.
