[TowerTalk] how much redux

In my opinion, you really need to rethink what you have planned.  Just 
because nobody is going to get killed climbing the tower doesn't mean it 
isn't going to cause property damage or physical harm when it falls 
over.  Imagine the leverage that 40 feet of tower has on 18 inches of 
concrete base (the radius) ... it's huge.  Plus, your elevator is going 
to add even more wind loading than would be the case just with the quad 
and rotor, and you're already exceeding the manufacturer's specs.

Which brings up another point.  If someone does get hurt as the result 
of an installation that you know up front doesn't meet spec (and 
therefore code), it seems to me that at the very least you have an 
indefensible position in a legal proceeding.

Lastly, if you don't include the guys up front, how are you going to 
determine whether or not they are necessary later?  Once the tower 
starts to tilt in a strong wind it isn't going to pause while you add 
the guys.
