CTE

Ron's right, Eddie.  40# is enough.  You have to keep in mind that if another plane passes by you at close range and its wings catch your pull pull cables, you want that cable to break, not pull your airplane apart.  Keith is also right about using different cables for each side (wish I'd done that!).  
   This sounds ridiculous, but it's happened to me!!

    I see a reference to 40# Kevlar, which triggers a question.
    What strength Kevlar is needed. The airplane pull-pull system I've seen state 100#. I've read you can use Spiderwire fishing Kevlar but the strongest I've seen in that is 65#.
     
    This may be a dumb question, but I'm attempting to setup elevator pull-pull for the 1st time & don't want to creat a problem with line that's too small.
     



  I use nylon-covered steel fishing leader. I normally use 40# and I've never used stronger than 60#.

    I weighed a carbon pushrod once that was ready to install and weighed around 1.5 ounces and I believe the 40 lbs. coated fishing line stuff weighed only a few grams...Kevlar would probably weigh only a couple of grams.
     
    Have fun,

     Gray what is the CTI for balsa ? I have carbon push rods / balsa fuse and my elev trim moves around considerably. I suppose it is because of humidity variation between the shop and outdoors ?? The pushrods are 50" long.      NatPenton
