Researched rudder & elevator cables tension

Initial investigation of the required tension of the control cables led me to this coment by Chris Ayer on the Zenith.Aero Builder's Site:  "around 20 lbs on the rudder cables and around 30 lbs on the elevator" whatever that means. But like Ralph pointed out if you give full right, forward elevator the up-elevator cable will tighten and loosen when left turn pressure is applied. I put mine in the neutral position and tighten it only to the extent I could get that full right deflection (thats the top cable). I tighten the turnbuckle on the bottom cable until it was almost straight.(slight sag). My rudder cables are spring loaded so its a mute point (I recommend spring loading the rudder cables). I have flown my 701 for 25 hours thus far with excellent results."
