TRF,
What is the judging criterion for world record “biggest” model or hobby rocket? Is this category recognized by any official records committee such as The Guinness Committee?
Regardless of flight performance it seems to me the best criterion would be:
Size = (Total volume enclosed x total installed impulse) / 1,000,000
I like that criterion because it combines the two prevailing notions of “biggest”, physical size and power.
By that criterion and using rough numbers:
1/ 10 Saturn V = (3,770 m^3) * (181,000 N-s) / 1,000,000 = 19.3
1:1 V-2 = (12,720 m^3) * (30,794 N-s) / 1,000,000 = 11.1
A theoretical 3-foot diameter by 36-foot rocket flying a 100% Q-motor would score:
(9.6 m^3) * (164,000 N-s) / 1,000,000 = 1.6
