I bought a new Cheetah and am having tuning problems. Every time i shoot I can see my arrow fishtail to the right. I shoot a 29" draw at 70 pounds and use Easton Axis arrows with a 400 spine. I have checked the cam and have moved the rest but it didn't seem to help. Is the spine on my arrows wrong? Please help, i'm getting frustrated.

No spine is right on. Have you paper tuned and/or walk back tuned the bow?

When i paper tuned, i moved the rest. Is there something else I have to move if that doesn't work? How do you walk back tune, i'm not familiar with that. Thanks for the reply

If that doesn't work or you don't understand let me know. I think I have the procedure on an Adobe file some where. I can email it to you.

OK, I tried paper tuning my Cheetah last weekend and sometimes it hits great and sometimes it tears high and to the left. I have been shooting for fifteen years so i know it's not my grip or torqueing the bow. Do i need to tune inches from the paper instead of feet? It's really getting frustrating that i can't get this thing tuned. I checked the tiller and they are both exactly the same so i know it's not that. Please help.

I believe that your spine is in fact wrong. You should be shooting an arrow with a 340 spine.

That's my guess, too. Before going out and buying arrows though, try turning the bow down two turns and shoot through paper again. If the tear improves at least you're on the right track.

Oh, yeah, check for cam lean and correct it too, if need be.

If I turn it down two turns, at about what poundage will I be shooting. If this does fix the problem does that mean if I turn it back up and get 340 spine arrows it will be ok provided I check for cam lean? Thanks so much for your help, this is extremely helpful.

Whether you turn it down or not you should still correct for cam lean if your bow has it. Taking two turns off the limbs will drop the bow about 6#. If your arrow tuning gets better by doing this at least you will have an idea that your arrows are underspined.

At this point you have two choices. Spend another $100 for new arrows in a 340 spine or shoot the bow at about 65# with your present arrows. I've always gone with the second choice because it doesn't cost any more and is easier on the body over the long haul. Ain't no critter gonna know the difference.

Im going to jump in on this one too, I am currently at about 73# at 28" draw, I shoot a 400 spine arrow (gold tip 5575) right now, for hunting purposes I would like to drop probably 6-9 pounds of draw weight, is the 400 spine arrow going to be ok at the lower draw weight?

Absolutely. In fact, maybe your 5575's fly Ok now, but in most cases I'd recommend a 340 spine for your specs.

I turned my bow down one turn and the problem corrected itself. I agree, I'll take the cheaper road and shoot a little lighter poundage with the same arrows. Thanks so much for your help, I learned a ton.

Glad it worked. And FYI there is tons more to learn. Maybe if you're like me the more I learn the more I want to learn. And most of the stuff you learn helps with any bow you get at a later date. Basically they're all the same when it comes to tuning and such.
