I don't know the thickness but it's in the neighborhood of .050". I found that the behavior of a 1.5 gram motor depends on its length regardless of the number of strands. My record motor was 14 1/2" long before the first wind.

The drawing of Chris Goins' MicroPoker is attached.

  The Nov. '09 issue of "Free Flight" had information about Bill Gowen's record setting F1M including some motor data.
   It was flown with a 3 strand motor, 39 cm long weighing 1.47 grams. My questions are:
  I see the three strands in the photo, but how is the motor is attached to the prop hook & rear hook? I.E. How are the two loose ends of the rubber attached to the hooks?
  Also, I assume the 39 cm length is 1/3 of the total length of the rubber strip. Correct?
  If this is true, I estimate the cut dimension of the rubber to be approx. 0.032". Correct?

  Thanks,
  Gary Hodson
