If i adjust the drop of the launcher arm and my nocking point I should be able to alleviate the clearance problem correct? once the clearance is resolved the flight should be truer and that will resolve the sight clearance problem and my need to have the sight very low to make up for the screwy flight path?
Something on the fall-away:
One may need to change the way a Lifting cord is attached. And you will need a marked measured off arrow for tuning.
Put a short serving 2-3” (serving size .018) at the point it is to be attached. Tie a short string nock in the middle of this serving. However you attach the Lifting cord, do it in such a way, so it can be moved & set by rotating the string nock up & down. You can then experiment on bringing the rest up from say ¾” to 2” more or less @ 1/64” at a time. Keep a record on what goes on.
When you put new fletch on an arrow look at it in the sunlight before you shoot it, & look at it in the sunlight after each time you shoot it making sure there is no contact. You will see a mark if there is.
And the fletch and the side of the fletch the mark is on will be a clue.
