Project Upscale Thor
I liked my Level 2 rocket so much that I up scaled it to a 5.5" version from scratch. I bought the up scaled decals from Scott Binder, the original owner of BSD Rocketry. Below is a picture of the kit along with the up scaled version with my son. Who has grown considerably since then (Feb 8 2003).

Here are some flight pictures through the years:
