Are you on HPA? I've written a bunch of stuff there about my gliders that you might find helpful. Pretty much every one I build is different but I can draw up a plan of WIF5 for you.

  Speaking of which....do you have a plan of that Std CLG you were flying? If you do could you send it to me separately at themaxout_at_aol ? Thx...

    Yeah that's what I meant by "underhand" for the second knot. I rarely change the direction for the second knot. Sometimes on big LPP motors the first knot won't hold unless you reverse the second one.

    I fly a little rubber occasionally!

      I spoke to "master" and he said that one overhand knot RH and then one overhand knot LH using what you describe and he has never had a not come undone. Plus...you are a glider guy...(!)

        I never had much success with this idea - probably has something to do with saliva quality. I lube lightly before tying then use two overhand knots.

        Old story but maybe some haven't heard it yet:

        To make an exact weight motor, cut strip to desired width but a little over the desired weight, lube, put on o-rings, put on scale, cut off strip to exact desired weight. Tie one overhand knot as close as possible to end of motor, then spread the strands to move the knot as close as possible to the end of the motor. Tie a second overhand (or underhand) knot inside of the first one and spread the strands to move the second knot tight against the first one.

        This procedure looks brutal but I've never heard of anyone having problems from it.

          Just wondering, when I show the students know tying, I have them soak
          the knot with saliva before pulling it tight and lubing, rarely get a
          break at the knot and it really pulls up tight. Anyone here do this ?
