Fletching damage

So far I've taken about 60 shots with my Tac and the same bottom right fletch on every arrow is trashed and split in the middle. The other three are wrinkled from the whisker qiscuit which is normal but that one bottom right is almost ripped off. This doesn't seem right! Is anyone else having this problem?

Which TAC is it?

Is there anything along the right rail that might be catching the fletching?

Is there anything different about right side of your TAC, say how cables cross?

Are the arrows' knocks set to where Left and Right fletchings are level or positioned at same angles in relation to bow's rails?

Re: Fletching damage

Okiebowie, I have the Tac Elite. The fletching is level when nocked and I always nock the arrows with the same side up every time. The only thing that looks like it could be a problem is the cables. That is the side they cross on. I paper tuned, and with it at full draw there is only about 1/8 of an inch max between the arrow and cables. This seems like a design flaw. I have 6 tac arrows and after about 60 shots total, all 6 need to be refletched.

On my TAC 15, there is about 1/4" of clearance. I am wondering if the paper tuning has your bow setup wrong, thus causing your fletching problems.

An arrow notched at rest should not change its inclination when it is at full draw.
If you place a TAC to where its rails are level front to back, a notched arrow should also be level front to back. You need digital level, such as Clinometer app on iPhone to check level to 0.1 degrees.

Harder method to check rest height, and you will need a dial caliper. The center of Whisker biscuit should be same distance from rail as center of string from rail measured at rest and also at 3/4 of full draw (part way forward so you can measure string center).

If you are really having to position Whisker Biscuit to where it sits low, whereby arrow has a downward incline, then there may be something wrong with your limbs. A mismatched pair of parallel limbs is nearly impossible to tune and will cause an arrow to have an eradicate flight path.

Re: Fletching damage

I have also papertuned and found that I had to move my arrowrest way down. So far that the arrow is obviously angled downward. I believe it has alot to do with the design of the bow. for instance when the string releases from the "slide block" it drops down, which i believe makes my arrow level during the shot. If you attach the slide block to the string and nock an arrow, stand away at the rear of the bow and look at the line of the string. It angles up from the cams to the slide on both side, both cocked and uncocked. When you pull the trigger the string drops while it is moving forward, changing the angle of the arrow during the shot. I tried leveling the arrow and all that like Andy had said in an old thread about setting up your Tac. but during the shot all that is out the window. After I posted about it, he too papertuned an Elite right off the shelf and found everything I'm saying to be true... so much so that he deleted the "set up" thread and said he was getting with the engineers to find out why the bow is designed that way. I have not heard anything more about it. My bow is shooting perfect "bulletholes" at 7yds., 20yds., so the arrow is definitely launching and flying correctly.

How did you determine that string is dropping down upon release?
Something Hi-Tech like High Speed Video Camera or something Low-Tech like string making brushing marks?

Has he seen this on more than one TAC Elite or just the one?

Hard to imagine why a TAC Elite would be designed to where string is held upward to where upon release the string immediately drops downward. Which has me wondering if there was a bad run. Caused by some machining process that got accidentally and temporarily changed or there was a mis-calibration of a machine that went unnoticed. Could even be a case of repetitive human error by one person on a changing shift schedule.
