Hello ROC I am hosting a group build with six year olds. This started out as a small build with my boy and some of his friends. Now I have about 35 builders. The kit I selected is the Estes M-104 Patriot. I am hoping that some of you experienced group builders can offer me a few tips or lessons learned. Some of my questions are how much space is needed per builder and how many kids per instructor. Thank you, David Baldovin 714-612-9069 -- ROC-Chat mailing list roc-chat@xxxxxxxxxxxxx //www.freelists.org/list/roc-chat
