RE: Vortex Metrics
Victor,
Unfortunately ALL the Vortex quickees are built a little different. Since the fuse is not made from a mold, each plane has a different length nose and tail moment (which is pretty minimal). I can give you the rough dimensions.....
Typical nose length (as you requested) is around: 4" minimum and 4 1/8 maximum.
The tail moment is about what you said, 13.75" to 14"....
I will also say that these dimensions are not performance related, as much as I would like to think they are. These measurements came about for balancing reasons, concerning the radio gear.
