I tried a few of the free catapult plans on the web with limited results, then finally ordered several  sets from Trebuchetstore . I did not believe the difference. Step by step, from shopping for parts to presentation, it could not have been easier. W.K. New Hampshire

We used the Davinci Trebuchet for Six Sigma DOE (Design Of Experiment) training with excellent results. By varying two factors : counterweight mass and release loop size, we were able to design and perform the experiment in a reasonable amount of time. Thanks. R.O. New Mexico

Thank you so much!  I didn't realize how quick it would be here.  I don't know who is more excited my son or myself! Merci. E.A. Canada
