Here is Big Bertha all folded up ready to go. i still need to work on a way to let the flappers down when I WANT to.

Well one way you could guarantee the drop would be to use a cam, but in order to keep them up… what about weak rubber bands that would snap when the cam spun?


the comp was today and i ended up with a 2-2 record. was a lot of fun!

I re did the lifting/dropping way. I moved the motors around and made two winch systems. It worked out a lot easier and allowed me to drop them a lot easier. I’ll upload a picture sometime later.
