Hi Charlie,
This Master Motor Matrix is nice, thanks! If I could make a few comments:
1) Could the column headers please be at the top of every page, not just the first? Pretty sure this is just a checkbox in Excel.
2) The final column (Notes) calls out when
some special hardware is required, but seems to miss other cases. Like aren't there some 38mm motors that require a special forward closure? And I know there are two sizes of aft closures for 38mm, but not which loads require which one. Similarly, it should be marked which loads require the FSD vs. loads that don't. So I think there needs to be a lot more notes making it clear
any time special HW is needed.
3) There's an extra "m" in the J510W-14A's Length column. This column is also inconsistent on when there's a '"' mark vs. not, the header states the units as inches, so having the inch mark in some of the cells seems redundant, but this is mostly my OCD speaking.
4) Any chance this could also be published in Excel form? For example I'd prefer to see the Peak Thrust column in lbs to make the T:W math easier, would be easy to add a new column and hide the existing one if I had the 'source', but a lot harder when I only have a PDF of it.
If something like this was always kept up-to-date that would be fantastic, I could keep a copy (for me the pages starting at 38mm) in my range box and always have the reference on what motors fit (based on the cases I have and the length of each rocket) as well as the basic details I need to decide if it's a motor I want to try (appropriate for the rocket's weight & weather conditions, a propellant I like, etc).
Something that confuses me a bit (never really noticed it until looking at this sheet, assuming it isn't a typo), how are the fastest
and the slowest burning motors both Warp9 propellant? I.e. H669N/I49N, and I59WN/I1299N. Is that really just the difference between a cored grain and an endburner? If so, wow.
