If you guys know what a slapper is, just put your gear ratio in too. If you can put how much teeth you shaved. Thanks!
13358A , My team we used a 8.33 to 1 Torque Ratio , our slip gear is a 36 tooth that has two sides of it shaved off. However Our catapult is horizontal and not vertical so I would recommend using sharpie and either a sander or a dremel (with safety In mind ) to go through the design process with your gears and team to design the catapult to figure out what would work for you. Try Making a single sided or maybe a double sided .
For a slapper you need to figure out torsion or the amount of force the slapper needs to overcome. To determine the gear ratio and if you need to swap the motor cartridge. But for a slapper all it is a slip gear that rotates a large gear backwards then at a certain point causes the slapper to launch forward. So this would need a single sided slip gear
Review the two physics Ideas of tensions and torsion to figure out gear ratio that would be needed. Then review the idea mechanical advantage as well. The other thing is the concept of turnover which is how much power does it need to start moving, we had a problem with ours where after a certain number of rubber-bands the motor couldn’t turn over the gears

For easy accessible explanations on this stuff go to the BLRS wiki
My team is using a 60 to 36 tooth gear ratio with the 36 tooth gear having 7 teeth sanded off. We have a “slip-gear” catapult but like 3324X said it requires testing and finding what feels best for your team. We like strength over speed. our catapult is slow but powerful, I have seen other teams that have fast but weak catapults.
