Yesterday was a wonderful day for launching rockets around here. So my brother and I set out to launch the only built and non-damaged rocket I have on hand - Estes' Snapshot. We did two launches and the second, which was this rocket's fourth launch, proved to be too much for the adhesive Estes used to secure the fin/motor mount assembly to the body tube. This provided me with a direct view into the bowels of the rocket. I wasn't at all surprised to find it caked with engine residue from the four launches, but this did bring to the forefront of my mind the issue of cleaning the rocket out every once in a while.
Is this a good idea, or is the engine residue buildup a non-issue? How would you go about actually doing it? I'm not really finding much on long-term rocket care.
