RE: NAP 4000 drop away ??
Troy, I' ve had the 4000s on all my BowTechs since they came out. I' m completely satisfied with them, and have had no problems. On your bow:
Draw it back & have someone mark the cable rod at the back of the slide at full draw.
Adjust the lifting cable so the launchers are just fully raised at this point. Otherwise the cables will bind.
Start center shot 3/4" , measured from the riser to the center of the arrow.
Start nock point 3/16" high.
Adjust the rest to raise the arrow level with the rest mounting holes.
Put something on the shelf to allow the rest to contact it as a stop. Don' t use the rubber guide that comes with the rest. I also put mole skin on the shelf for noise.
If the cable contacets the arrow you can put a twist in it to stop the contact.
Now tune & shoot. Good luck.
