OK, I did a little search and really could not come up with some concrete numbers and current methodology about the goonies of yesteryear and today.

The originals were 13mm but people today seem to use the Baby Bertha kit to make goonies. Does that mean the current batch of goonified models are 18mm models? Also what are the tube lengths? Are people keeping the BB kit intact and just modding the fins/canopies/etc? The old Estes catalogs just state the goonies are about 8" long.

With the surfacing of the original sketches I am getting the bug to make some goonies. While I might make larger versions later on, the 13mm would be great for my small areas to launch. I did see a post (by scigs30?) showing some original kits and it appeared that the tubes were 5" long. I am going to ask on that thread also but am also wondering about some of the other things I asked just above.
