Very good idea's...I now just use a plain piece of paper and write down all the particulars, but having a form is a good idea.
Back in 1967 when I started my rocket career, I just used a small Hearld Square Record Book ledger (I still have it, although its falling apart).
I just recently entered all of my records into an Excel Spreadsheet. But will soon to convert to a html or similar form once the kids are home from college - meaning that's their summer project.
I enjoy looking back at my entries and read my 12 year old writings....here is one:
"November 20, 1968, Little Joe II, overcast - about 40 Deg, Result: Poor. Engine C6-3, Church Launch Site, Flight #3. Altitude 200 Ft (guessimate). Remarks: On launch rocket rolled left then right in a Left Hand Loop. Ejection Charge went off as rocket impacted. Dad won't like this!, noticed before flight that one fin was loose, I used scotch tape, maybe bad idea. Rocket destroyed may be a couple of months before I can get another one."
In retrospect, I now perhaps now know that CG and CP were the reasons for the bad flight. The flight before I mentioned about wanting a higher flight, I took the nose weight (washer) that Estes had directed to be added with the screw eye.
