Anyone know what the starting centershot setting should be on Helim? I set mine at about 11/16 but that left with with a left tear. I did not have a lot of time but it did not seem right that I should move it closer to the riser (typical correction).
Billmost all heliums we set up are at least 13/16″ if everything is correct. it may be a torque issue.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktechgg, Pretty sure Im not torquing, been at this a while. Im thinking I need to check idler lean and adjust center to more like 3/4 (guess). I have not seen any spec’s on this for a Helim. My Legacy is good at 11/16.
Oh I have a Rip Cord rest.
Billthose are possible problems,but tear is showing the need to shove it closer to the riser.you seem confident it’s not you,so i would look for fletching contact and timing issues of rest.it would also be nice to have your arrow specs,draw length and poundage for diagnosis. the helium is quite a different animal than the old legacy.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktech

Agreed! Mine is dead on 13/16″
Joined: 11/3/2009Mine is just a whisker outside of 13/16″.

If your a right hand shooter and getting a left tear… move your rest to the left[/size:1lhhbspj][/color:1lhhbspj].
Try it…you might like it.
Good luckMakes sense to move it left. I think my initial setup is too close to the riser.
Billif you have a nok left and you move it left,the tear will get bigger.but do whatever you want. the left tear is caused by the arrow running into the inside prong on the rest,which kicks the tail of the arrow left as it passes thru the rest,which means you would need to move it right for it to line up properly.but,as i said earlier, they like 13/16″,something besides centershot is more than likely your problem. we sold and set up over 100 of these this year,just telling you what our experience is.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktechPaper tune: #1 shot high-right tear. #2 shot, lowered nock point, right tear. #3 Shot, moved centershot toward riser, slight improvement. #4 shot moved centershot more toward riser, no improvement. #5 shot, moved center shot out away from riser beyond initial setting, tear improved. #6 shot moved centershot out more, near bullet hole.
The truth is you’ll get a lot of advise, but none of it is 100% correct. Much depends on the idler lean, which also relates to how you grip the bow, the dynamic spine of the arrow, whether the nock orients the stiff side of the spine in the vertical plane or not, whether there is nock pinch or not, and whether there is fletch contact or not.
First step is always to correct idler lean and eliminate nock pinch.
Next step is always to verify fletch clearance, then verify rest timing for a drop away, and to eliminate any lateral string deflection due to string pressure on the face.
A properly spined shaft will always tune easier, but if the shaft is slightly weak, it still is possible to tune for target points if there is no nock pinch and the stiff side, if there is one, is oriented in the vertical plane:
Note that it is possible to get the centershot so far off the centerline of the powerstroke that the paper test shows the second oscillation of the arrow. This is why it is important to paper test at two distances or more, usually 5′ and 10′ are sufficient. When in doubt, shoot the paper at 1′ … you’ll have to draw the bow then move up to do this, but it will show precisely how the arrow is leaving the launcher.
What it all boils down to is:
- Always correct nock height first before adjusting centershot
- Move centershot in very small increments. If things don’t get better, as in the first pic I posted, then move the centershot in the other direction.
… hope this helps.
