Placing any more than 12-18" above the rotor is nothing short of
crazy.  Wishful thinking would be the polite expression.  Waiting
for disaster is a close second.

Rotor load figures are derated by x2 by the second mast mount
fixture, as it is. 

I have assumed that those using longer masts are base rotating
the MA series towers.
