The Tampa Tripoli Prefecture launch is this Saturday (June 16).  Weather permitting, I will be attempting my Tripoli Level Two certification with a Binder Design Excel dual-deploy kit.  Here is my dual-deploy rocket checklist for this weekend’s launch.

This checklist covers items that need to be taken care of before you get to the launch site.  Let’s get started…
