- excluded engines like
- LFB KR-1x2 “Twin-Boar” because over 25% is fuel tank and contents
- RV-1 “Cub” because is radial attached or vernier or non-traditonal like aerospike
- Mass Calculation:
- Part I: (4 x 3) * (( 0.9375 + 1)/2) = 11.625.
- Note: Averaged the ratio of 15:16 with 16:16 (or 1:1) for a nicer feeling number.
- Explanation of math
- 4 = Mass of Vector
- 3 = Number of Vectors
- 0.9375 = Mass of the Mammoth (15) / Mass of Four Vectors (16)
