With an installed cable you are tensioning a sorta stretchable cable 
against a very springy airframe.  1 turn on the turnbuckle on one 
aircraft may change the tension twice as much as on another.  As a side 
note, Beech uses springs in the LG retract system with pushrod 
tensions.  Bonanza series.  Cessna uses the airframe as the "spring".  
300 - 400 series.

Dear Paul,

So, when you back off the tension 1/2 turn what happens?

A full turn?

The other way?

How many degrees of rotation per 5 pounds of tension change each way?

If you use those turnbuckle safety clips rather than safety wire, how 
much rotation can you get with those installed?  (We are talking about 
the Zenith supplied turnbuckles)

Thanks,

Sabrina
