Hey guys, I know this is an old thread, but just wanted to give my input on NuFletch. I have been shooting the product for a few seasons now and I know the science behind it does not make a lot of sense, until you really think about it... First forget everything you have ever heard about arrow flight, it is all theories. First the facts... In common sense terms, your taking a long skinny, flexible shaft and launching it at speeds over 300 fps, the first thing it does is flex (oscillation) each time the arrow flexes it sheds kinetic energy. Through out the entire flight an arrow is trying to recover from oscillation, continuously shedding kinetic energy. If you sit back and think about an object in flight and what you think would make an object fly the best, does putting all the weight in the front of that object make any sense? Think of an arrow as an airplane, if Boeing took all the weight and put it on the very front of their planes we would all be dead. An object in flight needs balance. Think about that. Now the science of adding NuFletch to your arrow. Step 1) Cut 2 3/4" off the back end of your arrow. This gives you a shorter arrow shaft, which makes the arrow more stiff. Step 2) Glue an insert and screw in the NuFletch product. Yes, you add weight to the back of your arrow. But before freaking out think about what you just did. You threw the theory of FOC out the window and you now have a balanced arrow. Step 3) Paper tune your bow to the new arrows. Your bow was paper tuned to compensate for oscillating arrows. Now that your arrows aren't coming off the string doing whatever they want, they are flying how they are supposed to. So now an overview of what has happened by adding NuFletch. Since your arrow shaft is shorter you eliminate oscillation. Since your arrow is recovering from oscillation before the nock passes your riser the weight you added to the back end is now your friend. Instead of losing energy, your arrow now retains it. Since your arrow is balanced it flies flatter. The energy retained is then stored until it hits something, and the weight in the back of the arrow then pushes through whatever object it hits, that is where you get the penetration. Now lets touch on the loss of speed, since that is what kills right? I would rather get hit by a pencil going 100 mph than a baseball going 75… So yes adding weight slows down your arrow. But if you look into all the speed test you will see they test arrow speeds from 1 to 2 yards. Who cares how fast your arrow is shooting right there? Test it at 20-30 yards where it matters. Since everyone doesn't own a chronograph just shoot a NuFletch arrow then shoot the same shaft without. Its obvious when the NuFletch arrow is buried 3 or 4 inches further than your conventional arrow which arrow is shooting better. I do not have any affiliation with NuFletch other than the fact I shoot it. I just get tired of seeing all the forums on how horrible of a product everyone thinks it is and putting something down that they honestly know nothing about. And to all the people talking about ordering multiple packs to furnish a dozen arrows, you're wasting money. You cut your arrows down and when you ruin a shaft you just unscrew the part and put it on the new shaft. All your arrows will fly the same; all the parts are machined rather than each vein being glued on by someone, which makes each arrow different, even if it is minimal. I am sorry to rant, I just get aggravated with people that think they know absolutely everything about everything. NuFletch is a good product, the science behind it helps my arrow flight, penetration, and grouping, not to mention being able to re-fletch an arrow literally anywhere in about 6 seconds. Again, sorry for the rant, I just felt like people needed the truth and have everything broken down for them. Ill be more than happy to give more of my input if you have any questions. No I don’t think I know everything, I just wanted to give some positive feed back on this thread.
^This! When I put my new string set on my bow this happened to me also. I did what Trial has said here and added twists to my cable and got back up to 70lbs
So im new to archery and i picked this bow up for $20 dollars for my son it is a xi Silverhawk xp i know they are no longer made but does the theory "if i change the draw length can i alter draw weight" because i want it down to the 30-45 range where now its in the 35-50 range and limb bolts are pretty farout and wont go below 40# Bear Archery Whitetail Supreme XLR 29" 70# 3D Target Fanatic
