If you consider them as the body of an AVION,then:
*an 11-footer is Cd 0.38
*an 18.5-footer is Cd 0.230
*a 27-footer is Cd 0.205
*a 38-footer is Cd 0.200
*and a 45.5-footer is Cd 0.205.
So your 35-footer is near the bottom of the drag bucket for these shapes,making it the lowest drag length.  |
That's just the basic body shape, correct? Real numbers would be higher?
