150' 1/8" Kevlar Cord
200' 1/4" - 5/16"  Steel Cable
1    5 Pound Weight
Bow and Arrow or other line thrower

  Wind Kevlar cord in such a way as to allow it to spool off.
  Attach one end to arrow and other to spool of steel cable.
  Have cable wound as kevlar to allow spooling.
  Attach 5 pound weight to loose end of cable.

  Use Bow and arrow to launch the kevlar/cable arrangement in to teh Chopper
rotor assembly as close to the cyclic (Center of rotor mast where controls are)
as possible.  The cable cutter device on the chopper cannot function on a loose
cable.  The cable must be tense in order for the cable cutter to function as
designed to cut cables (power lines) suspended between towers. After a few
wraps of kevlar around the rotor,  the cable will be drawn into the rotor
assembly also.  At the end of the wrapping the 5 pound weight will tighten the
cable enough to interfere with the cyclic control and bring the chopper to
earth.

   Range can be increased if the Kevlar is increased in length.  Go out and
shoot some kevlar before you try this so you are familiar with its' shooting
characteristics.

***  NOTE  ***

   Steel cable will not be pulled aloft by an arrow.  The kevlar must be in the
rotor to draw the cable up.

   The chopper will not land softly,  so don't try this on a friend's chopper.
The occupants could survive this and be fighting mad when they hit the ground
so make provisions for this.  The chopper will fight no more this day.

  I picked this up from a very good friend that was a E-9 in Qinh Uon for the
717th Air Cav.  He did extensive research in chopper stopping during Nam.  He
assures me this is unstoppable if done right,  and done within range.  Usually
the range is about 150' with the Kevlar of 150'.

Great info!  I will pass it on.  The bow and arrow reminded me that on ships we
used a "Lyle Gun" (sp) to fire lines between ships.  I have one that was
factory made by Springfield Arms....it is a short barreled 45-70 that fires a
blank cartridge with black powder in it. A rod about 10" long is shoved down
the barrel.   The rod has a round hole in the end, making it look a bit like a
long thin sash weight. A cannister clamps on the underside of the barrel and
contains several hundred yards of heavy cord.  The other end of the cord is
fastened to the line that you want to run between the ships.  I have also used
similar guns that looked like a signal cannon.

Also....would nylon seine twine work in place of the kevlar?  On ship shafts it
melts and causes the shaft to lock up.....it is also cheap here as we use it
for repairing fish nets...
