We fill the cylinder with any-old slow valve while we're holding it down with an electro magnet holding a puck of steel on the catapult. Let go of the magnet and it flys!
Here's the magnet we're using this year...5.6 watts/ http://www.mcmaster.com/#5698k116/=118b3ox |
Wow this is neat but I'm not sure how well we'd be able to mount it given our current setup. I will be sure to look into this though. Thank you! Do you have any pictures of how you've mounted this on your bot?
