Double Up #1

Double Up #2
Wow, I feel like a celebrity. I can't say enough about the Double Up rocket. I'm working on a more formal review for TRF but this rocket is a winner! The B6-0/B6-4 sent this rocket out of sight. Straight flight with no wiggles or roll. This was my first gap stage rocket. A lot easier to prep than chad staging. John... you did it again!

Awesome John ........... I can think of another gap-stage project !!!! and You know what I'm talkin' about !!! .... lol

Great job on your part of the process too Keith !
Nice work Keith! Looks like you are enjoying the gap staged LPR rockets. I tell ya, they are a breeze to prep. I certainly prefer this type of staged rocket over the traditional cellophane taped direct staging rockets.
