Ancient NAR Motor Data C5-3
 
Does anyone have a copy handy of the NAR motor test results?

Estes C5-3 or Centuri C5-3S (same motor)

I'd like to compare it with other actual NAR data, not catalog specs.

I'd love to see an NAR graph too!

I know I have one but have not been able to find it.
May be on a very old laptop...will check that next.

Is this real NAR data?

It's actually still on the NAR site....I just had to change the file name manually. https://www.nar.org/SandT/pdf/Estes/C5.pdf

The same trick didn't work for B14s however.

Now I'm curious about real tested B14's, especially the older ones.

It did for the B8, though. :cool:

I did the same check last week. I was going to contact NAR and see if the old test data for B14s is available for “research” purposes.

I've set up a spreadsheet to compare Total, Peak, and Avg thrust with clusters to compare them with larger single motors. I'd love to compare some clusters to real B14 data. Of course, that's only if they provide an early enough example that shows it's a real B14 instead of a rebadged B8.

I'm almost positive I can successfully fly Saturn V on a triple B6-2 or B4-2 cluster! Peak thrust is greater than a single D12 and total impulse is only a few ticks lower. Probably would only get 75 ft!!!! :chuckle: :D :chuckle: :D
