Hi, my friends and I are in a competition regarding trebuchets. The rules can be googled: MESA 2007-2008 Trebuchet Rules (California). We found this site to be very helpful in trebuchet designs; however, we are looking at designing a FAKA, this seems to be the most efficient. In order to build this, we need to know how the arm operates. (How we build it to have a primary and secondary trigger.) If we can get some help, that would be GREAT!
We are also looking at other suggestions at trebuchets. (F2K Series disqualified)
