Do I have defective limbs?

[Progen]

I've had these XQ-1s for about 3 odd months now and noticed the following :-

1. Brace height goes down by about 0.2 to 0.5 cm every few weeks.

2. I may be paranoid and haven't checked with a bow scale yet but for the first time in my shooting life, I'm experiencing a little stacking. My drawlength to the button is only 26 inches so that's something I've never encountered with any decent limbs out there.

3. Tiller still feels neutral (that's the way I set it) but the arrow spread in both axises is inconsistent at 18 metres and sometimes even nearer. I do shoot almost daily so I don't think my form's THAT bad.

Do I have defective limbs? According to Win & Win, mine's from 2004. The dealer where I got it from sold them to me cheap because they were old stock but he's also thrown in a warranty. I can either exchange them for brand new FX's or Winact Synergy's at no extra charge. Thought of getting the Samick Masters or Extremes though if these limbs are really faulty.

ps. The string used is Angel ASB Dyneema with Angel Majesty serving. Has gone through at least 1500 shots by now and the drop in brace height is still occurring.

Here are some photos of them.

i doubt it is because of your limbs. in theory, your limbs shouldn't change shape or form if you treat and store them safely and responsibly. firstly, you should eliminate as many factors as you possibly can before you declare your limbs defective.

how's your limb alignment? if they're twisted or slightly warped when your bow is strung, then there's your problem.

your brace height may change because of the material the string is made out of. some materials stretch the more you shoot them. stretch = longer string = decrese in brace height.

as for the arrow spread, it may be numerous factors. it could be you, the way your bow is tuned, or the weight difference between each of your arrows. although the tiller may feel netural, measure it with a bow square. try a positive or negative tiller and see how the arrow spread is like then.

it could also be a clearance problem. do a powder test. i use baby powder mixed with methylated spirits, and brush that on. works well. easy to clean off too.

The more input, the better, isn't it? Especially since there were quite a lot of negative rumours about the XQ-1s. The reason I took the risk was because the agent offered a 6 month warranty on them during which I could swap for other limbs. Anyway, what the retailer suggested was to give it another few more weeks, take brace height measurements every few days to see the total change over a period of a few weeks and then get back to him. The agent will still honour his earlier commitment.

And Bulls On Parade, thanks for the suggestions.

I don't think it's the string because that has gone pretty close to 2000 shots by now.

As for whether the limbs have twisted, I can't really tell from sighting alone. They look fine, visually. Limb to riser alignment is fine too as shown by the Beiter limb gauges.

Arrows are weight matched to about a spread of 0.2 to 0.3 grains. Already got flamed for taking that much trouble although I know some folks match them precisely. :-D

I might try playing around with tiller as a last resort although I don't think tiller will cause little changes in brace height. I do like it neutral.

You beat me to it, George.

Seems pretty unlikely that your brace height would be going down over time because your limbs are buggered. For it to go down, the limbs have to stretch the string more and bend less - if they were delaminating you'd expect them to bend more, if anything.

This was one of the replies from Sagittarius.

My first set XQ-1 bend to the left.

My second set had the same problem you are experiencing.
The tiller changed from starting shooting at 22,5 (medium limbs) to 21,5 in about 100 shots. So I didn't even got the chance to shoot a Fita.

He mentioned tiller instead of brace height (I've started taking note of brace height and tiller settings now) though. Anyway, the retailer's curious and as said earlier, the agent's ready to stand by his promise. I'm also waiting to hear what Win & Win has to say. Looks and qualitywise, it's a nice set of limbs, especially with those carbon reinforced tips.

gt probably has more recurve nouse than this entire web site. Take your initial advice.

I did email Win & Win. Waiting for their reply and thought perhaps more light shed on this subject might be useful.

ps. What's nouse anyway? :confused: :-D

[Leighton]

Angel Dyneema never stops creeping and nous means common sense, knowledge etc. www.dictionary.com is your friend.

[Jay.G]

I'd love a pair of Fx's or a pair of extremes especially extremes. I think if you need to change limbs pay abit extra and get a pair of extremes though you may need to re-alighn your limbs but aww FX's...

definately.


Progen, how many arrows would you be shooting every week?

Oh ok, but the earlier strings made from the same bale settled in after a few hundred shots and didn't exhibit such changes.


Progen, how many arrows would you be shooting every week?

About 3 to 400. I don't shoot a lot but I shoot almost every day. Maybe 50 to 60 in the tennis court downstairs. I usually do a lot of 3 spots at 18 metres because that's my weakest. I'll shoot quite a bit more if I take my bow and butt over to the outdoor range.

[Leighton]

not sure if you have a winter, but strings creep more when its hot.

In the tropics, Leighton. Ok, that settles it then.

Now I'm just waiting for the reply from Win & Win about the stiffness. I shoot almost every day and haven't been ill for the past few months so it's strange that they are starting to feel a little stiffer and louder than before.
