For middle school Science Olympiad planes in 2004, we used Size 004 or perhaps 005 O-rings. I was trying to help the kids achieve some degree of reproducibility, perhaps sacrificing some ultimate performance.

  calgoddard,

  You and others have referenced the use of "O-rings" over the last couple
  of day's posts. I'm assuming that you are refering to the "O-rings"
  that can be found in the plumbing supplies section at Lowes/Home Depot,
  correct? I went down there to see what was available and there's a
  veritable plethora of different sizes and cross-section diameters. For
  those of us that are really new to this modeling domain and don't know
  enough to know if we like them or not, what are appropriate sizes for
  use on SO models? My sense is that you want the smallest that doesn't
  break. ;-) But what might that be?

  TIA,
  Jim Howell
