Notes

  • The SM-8 replaced the SM-5 as the quarter-scale KM trainer and test craft.
  • The file is an 18.5 × 9.5 × 5.5 m box. The source's weight figures conflict (16,094 lb is about 7,300 kg, not 8,100 kg), so weight is not used.
  • Marked secondary.
  • True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
  • Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
